| 00:13.39 | high-rez | Can you create a pdp context with it ? |
| 00:21.02 | tmzt | high-rez: with android? |
| 00:21.20 | tmzt | do you mean gprs or something else? |
| 00:23.15 | high-rez | Yeah, I mean with android - can the phone GPRS Attach e.g. create a PDP Context. |
| 00:24.29 | high-rez | E.g. use the cell phone's gprs/edge/umts/hs[n]pa modem :) |
| 00:30.57 | tmzt | I think you use Togga for that |
| 00:31.09 | tmzt | if you have the latest kernel from git umts should work |
| 00:31.17 | high-rez | Interesting. |

| 15:42.33 | par | how have you been |
| 15:42.42 | par | how is openezx going |
| 15:44.34 | stefan_schmidt_ | hi par |
| 15:45.03 | stefan_schmidt_ | par: Pretty good actually. Wyrm found a datasheet for the PCAP2 under a different name. |
| 15:45.34 | stefan_schmidt_ | par: The MFD core driver for it is already in linux-next and There is progress on all fronts. |
| 15:46.12 | stefan_schmidt_ | par: It's just that I'm not really into openezx kernel work anymore. Wyrm does a great job here. |
| 15:46.17 | stefan_schmidt_ | par: How are you? |
| 15:46.37 | par | i'm fine, |
| 15:47.07 | par | a lot fo what is occuring here is getting android up and running on various models lately. |
| 15:47.34 | par | personally i like htc-linux or (xanadux) |
| 15:49.14 | stefan_schmidt_ | par: (android) yup, figured it. |
| 15:49.29 | stefan_schmidt_ | is more interested in the kernel side tho |
| 15:50.06 | stefan_schmidt_ | What me really interests atm is how similar the msm6281 modems are to the modem part of the msm7k SoCs |
| 15:51.26 | stefan_schmidt_ | Athena seems to have a combination like this. An older pxa SoC and and older msm modem tho. |
| 15:55.03 | par | did you look at the code in angstrom for the drivers? |
| 15:55.34 | stefan_schmidt_ | What should angstrom have to do with it? |
| 15:55.43 | stefan_schmidt_ | I would search for a kernel tree :) |
| 15:55.48 | stefan_schmidt_ | http://github.com/mistadman/android-athena/tree/master |
| 15:56.09 | par | yeah well sorry i haven't slept all night |
| 15:56.18 | stefan_schmidt_ | That's what I found. But the htcathena_dpram_core.c is not in the repo. Mailed the author |
| 15:56.24 | par | yeah just check out the kernel.. |
| 15:56.54 | stefan_schmidt_ | par: Then better take a rest. Humans need sleep. (From time to time) |
| 15:58.51 | cr2 | stefan_schmidt_: i didn't work on the dpram linux driver, but did some disassembling |
| 15:59.04 | stefan_schmidt_ | cr2: ok |
| 15:59.17 | stefan_schmidt_ | cr2: Any pointer to some information about it? |
| 15:59.32 | cr2 | stefan_schmidt_: the main difference to the msm smd code is that the single channels use gpio interrupts |
| 15:59.41 | stefan_schmidt_ | cr2: mistadman was the only one workignon it? |
| 15:59.49 | cr2 | stefan_schmidt_: but it's similar to the blueangel driver. |
| 16:00.07 | stefan_schmidt_ | cr2: That's good news! |
| 16:00.21 | cr2 | yes, he did some haret tracing |

| 16:01.08 | stefan_schmidt_ | cr2: In which repo is the blueangel driver? |
| 16:01.10 | cr2 | stefan_schmidt_: you will have athena ? |

| 16:01.46 | cr2 | i want to copy xda-dev athena wiki pages to htc-linux.org |

| 16:02.15 | stefan_schmidt_ | oh, there is a htx-linux.org page. |

| 16:03.06 | cr2 | BA dpram driver also has 2 512byte rx/tx fifos |
| 16:03.10 | stefan_schmidt_ | par: thanks. Let's see if I still have cvs installed. ;) |
| 16:03.26 | stefan_schmidt_ | cr2: great, so I will have a look at this one then. |
| 16:03.50 | cr2 | stefan_schmidt_: i'm looking for the ba dpram driver link |

| 18:21.14 | cr2 | pH5-evoked ASIC3-like currents were recorded at -80 mV from cultured rat DRG neurons. |
| 18:22.20 | cr2 | wild-type homomeric ASIC3 receptor activated by pH5 either expressed alone (A) or in the presence of the ASIC3 |
| 18:23.58 | pH5 | hehe. |
| 18:24.25 | pH5 | "ASIC3, an acid-sensing ion channel subunit expressed essentially in sensory neurons, has been proposed to be involved in pain." |
| 18:24.29 | pH5 | sounds about right to me |

| 18:25.24 | tmzt | that's real? |
| 18:25.51 | cr2 | pH5: ASIC3, the most sensitive of the acid-sensing ion channels, depolarizes certain rat sensory neurons |
| 18:28.05 | cr2 | tmzt: for hw accel we still need to know the msm internals. |
| 18:29.00 | tmzt | think something like mmiotrace would work? |
| 18:29.19 | tmzt | or trapping pmem writes? |
| 18:29.31 | cr2 | pH5: what did you want to know about asic3_spi ? i digged out my athena archive now, can look at ba/sable too |
| 18:29.36 | tmzt | not now anyway, too many things need done first of course |
| 18:30.03 | cr2 | tmzt: yeah. rpc, nand |
| 18:32.51 | tmzt | is there a patch for returning true from the fbset ioctl? |
| 18:39.39 | pH5 | cr2: I wanted to know how to activate/reset the BA keyboard (is the reset gpio active low?) and whether there's another gpio involved apart from reset and cs. |
| 18:39.46 | pH5 | for what does athena use asic3_spi? |
| 18:44.05 | cr2 | pH5: athena does not have asic3. i had all devices in 1 directory, but now i see that the archive is splitted. looking for uni/ba/sable now |

| 19:24.42 | stefan_schmidt_ | cr2: I had a quick look at the blueangel dual port ram driver. It exposes an uart to userspace, but is not used for the modem as that one is on FFUART? |
| 19:25.13 | cr2 | stefan_schmidt_: it's used for pppd (gprs) |
| 19:25.27 | stefan_schmidt_ | cr2: ah, ok. Strange setup. |
| 19:25.38 | cr2 | stefan_schmidt_: it's a soft-uart driver |
| 19:25.57 | cr2 | with one channel |
| 19:26.00 | stefan_schmidt_ | cr2: You start the PDP context on the FFUART and then data over that one? |
| 19:26.12 | stefan_schmidt_ | Or everything over this one? |
| 19:26.27 | cr2 | smd on msm can be used for a multiport setup |
| 19:26.43 | stefan_schmidt_ | yeah, seen it |
| 19:26.56 | stefan_schmidt_ | It's also used for the gpsone technology from msm |
| 19:26.58 | cr2 | i call the umts number on 1 uart, get the connect and start pppd on the second uart. the same on msm* |
| 19:27.12 | stefan_schmidt_ | cr2: ok, thanks |
| 19:27.13 | cr2 | gpsone is a complex setup |
| 19:27.24 | stefan_schmidt_ | oh, really? |
| 19:27.26 | cr2 | you has one more uart channel for nmea |
| 19:27.38 | cr2 | but the control goes over rpc channel |
| 19:27.40 | stefan_schmidt_ | I hoped it would be some gpio fiddling and then NMEA on the smd |
| 19:27.48 | stefan_schmidt_ | urgs |
| 19:27.58 | stefan_schmidt_ | That means I have to read the rpc things also |
| 19:27.59 | cr2 | hehe. sirf3 times are over ;) |
| 19:28.04 | stefan_schmidt_ | hoped to avoid that. :) |
| 19:28.23 | stefan_schmidt_ | cr2: depends |
| 19:28.28 | cr2 | it depends on the msm modem setup |
| 19:28.35 | stefan_schmidt_ | ok |
| 19:28.42 | cr2 | yes, i have sirf3 on athena. |
| 19:28.54 | stefan_schmidt_ | sirf3 on my eten here |
| 19:29.03 | stefan_schmidt_ | and ublox on the gta0* |
| 19:29.08 | cr2 | but msm wants that everybody uses their shitty gps implementation |
| 19:29.18 | cr2 | ok |
| 19:29.51 | stefan_schmidt_ | For hw vendors its nice to have it on board without a new chip, rf issues, etc |
| 19:30.03 | stefan_schmidt_ | But I also prefer a separate chip |
| 19:30.11 | stefan_schmidt_ | ublox5 rocks for that |
| 19:30.13 | cr2 | qcom is a hw vendor |
| 19:30.38 | cr2 | can you dump raw code phase data with it ? |
| 19:30.53 | stefan_schmidt_ | cr2: ok, let me correct this to product vendor |
| 19:30.57 | cr2 | i've heard that ublox without an external antenna is not great too. |
| 19:31.20 | stefan_schmidt_ | cr2: phase code? You mean the raw GPS stuff? |
| 19:31.43 | stefan_schmidt_ | cr2: Depends on the internal antenna of course. |
| 19:31.58 | cr2 | yes, raw gps |
| 19:32.08 | stefan_schmidt_ | even with ublox 4 we get could TTFF for the gta02s |
| 19:32.09 | cr2 | pseudorange and code phase |
| 19:32.33 | stefan_schmidt_ | cr2: Not sure if you can get that with ublox5. |
| 19:32.38 | cr2 | sirf2 could d that ;) |
| 19:33.00 | cr2 | but i don't know any free software that can dump it properly |
| 19:33.10 | stefan_schmidt_ | cr2: The global (b)locate does the same |
| 19:33.26 | cr2 | !free software |
| 19:33.40 | stefan_schmidt_ | cr2: There is even a SDR GPS project. So code for GPS calculation should be there |
| 19:33.52 | stefan_schmidt_ | heh, yes, global locate sucks :) |
| 19:33.55 | cr2 | :) |
| 19:34.10 | stefan_schmidt_ | remembers the bad expirience Openmoko had with them. |
| 19:34.18 | cr2 | yeah |
| 19:34.38 | cr2 | btw, does the pxa haret trace work on pxa3xx ? |
| 19:35.02 | stefan_schmidt_ | cr2: http://www.gps-sdr.com/ |
| 19:35.29 | stefan_schmidt_ | cr2: (pxa) Have to wait for the Omnia to arrive before I can test it. |
| 19:35.37 | stefan_schmidt_ | Should be here on monday |
| 19:35.38 | cr2 | wow |
| 19:35.45 | cr2 | ok |
| 19:36.01 | cr2 | check if you can dump the rom too |
| 19:36.18 | stefan_schmidt_ | But xsascha should know as he works on the samsung i780 |
| 19:36.32 | stefan_schmidt_ | will do |
| 19:36.48 | stefan_schmidt_ | Perhaps time for IDA again ;) |
| 19:37.21 | cr2 | ok |
| 19:37.47 | cr2 | well, it helps to have both ida+trace |
| 19:37.59 | stefan_schmidt_ | yup |
| 19:38.20 | stefan_schmidt_ | Going to tons of wimo driver assembly is no fun |
| 19:38.41 | cr2 | depends on the vendor |
| 19:38.55 | cr2 | i got used to the htc asm |
| 19:38.58 | stefan_schmidt_ | I have seen Harald doing it for the eten. |
| 19:39.11 | stefan_schmidt_ | cr2: (htc asm) I can imagine |
| 19:39.12 | cr2 | but others do weird things. |
| 19:39.26 | stefan_schmidt_ | cr2: How long are you doing this HTC thing? |
| 19:39.45 | stefan_schmidt_ | remebers he started with openezx in 2005 |
| 19:39.51 | cr2 | for a long time :) |
| 19:40.10 | cr2 | i think i bought ba in oct 2004 |
| 19:40.12 | stefan_schmidt_ | but we had the linux 2.4 sources there. No assembly needed |
| 19:40.59 | cr2 | a legendary device. pH5 hacks on it now. |
| 19:41.18 | cr2 | btw, does gps work on a780 ? |
| 19:41.36 | cr2 | my a780 can't talk to gps anymore |
| 19:41.49 | stefan_schmidt_ | ah, I thought Philipp works on magician only |
| 19:42.04 | cr2 | works= works with openezx |
| 19:42.16 | stefan_schmidt_ | (a780) We know the AT command to enable it. (connected to the BP) |
| 19:42.50 | stefan_schmidt_ | And we have some c code to parse the packets we get over the muxer channel to bring it into NMEA format |
| 19:42.54 | cr2 | yeah, i was thinking about cutting it from BP and soldering to STUART |
| 19:43.01 | stefan_schmidt_ | Not sure if it really works good |
| 19:43.07 | cr2 | ok |
| 19:43.16 | stefan_schmidt_ | I would say not working then. :) |
| 19:43.19 | cr2 | but then i need to load the firmware myself. |
| 19:43.34 | cr2 | and i have no idea where to grab this fw |
| 19:43.39 | stefan_schmidt_ | And the GPS is real shit anyway. Power hungry _and_ bad performance. :) |
| 19:43.50 | cr2 | hehe |
| 19:43.55 | stefan_schmidt_ | And the idiots build the same chip into the A1600 again. |
| 19:43.59 | cr2 | power hungry. that's try |
| 19:44.53 | stefan_schmidt_ | the fw should be embedded inside the modem fw |
| 19:45.10 | cr2 | once i've lost the gps signal at night in Finnland ;) |
| 19:45.10 | stefan_schmidt_ | I really think there are nicer things you could play with. :) |
| 19:45.33 | cr2 | yeah. athena with sirf3 on ffuart can't be beat. |
| 19:45.51 | cr2 | but gps on msm is pita too. because of the rpc ;) |
| 19:46.04 | stefan_schmidt_ | sigh |
| 19:46.21 | cr2 | not as bad as GL, but still pita |
| 19:46.33 | stefan_schmidt_ | The problem is more to get a new device with 3G/HSPA without the msm modems |
| 19:46.47 | cr2 | i think they do not exist |
| 19:46.57 | stefan_schmidt_ | Harald and me worked hours over hours with the eten |
| 19:47.07 | cr2 | everything i know uses msm |
| 19:47.13 | stefan_schmidt_ | No idea why the modem did not talk to us |
| 19:47.16 | cr2 | even my nc10 with "samsung" modem |
| 19:47.31 | cr2 | which cpu is eten ? |
| 19:47.31 | *** join/#htc-linux htc-linux (i=5745de6c@gateway/web/ajax/mibbit.com/x-0eed6059a6c5fa6b) |
| 19:47.58 | stefan_schmidt_ | The E-Ten using a Ericsson mobile platforms modem |
| 19:48.22 | stefan_schmidt_ | The current one are using s3c2442, next generation s3c64x0 |
| 19:48.47 | cr2 | hmm. ipaq6915 uses ericsson too. and i think it even worked. |
| 19:48.50 | cr2 | ok |
| 19:48.53 | stefan_schmidt_ | Besides the modem it was really close to what GTA02 used. Even the display is the same. |
| 19:49.05 | stefan_schmidt_ | oh, interesting |
| 19:49.11 | cr2 | is there haret support for s3c64x0 ? |
| 19:49.12 | stefan_schmidt_ | How it is connected? |
| 19:49.19 | stefan_schmidt_ | On eten it is uart + spi |
| 19:49.25 | cr2 | btuart +mux protocol |
| 19:49.39 | stefan_schmidt_ | IIRC Harald did a patch for the basic gpio tracing |
| 19:49.49 | stefan_schmidt_ | not sure if it is in haret mainline yet |
| 19:50.10 | cr2 | http://wiki.xda-developers.com/index.php?pagename=SablePhone |
| 19:50.16 | stefan_schmidt_ | hmm, how fast is the clk for the uart when they do hspa over it? |
| 19:50.36 | cr2 | the tty disc driver is in hh.org CVS |
| 19:50.45 | cr2 | 921600 |
| 19:50.52 | stefan_schmidt_ | hmm, ok |
| 19:50.54 | cr2 | not hspa, gprs |
| 19:51.03 | stefan_schmidt_ | ah, that makes sense |
| 19:51.15 | stefan_schmidt_ | The eten modem is hspa |
| 19:51.21 | cr2 | ok |
| 19:51.25 | stefan_schmidt_ | not really the speed for a uart |
| 19:51.34 | cr2 | hehe |
| 19:51.45 | cr2 | i get 310KB on umts |
| 19:52.41 | stefan_schmidt_ | Another thing. As you know a lot about the msm modems, perhaps the most outside of quallcomm and google. |
| 19:52.53 | cr2 | lol |
| 19:53.05 | stefan_schmidt_ | I heard from somebody I trust on this that they also have a binary protocol. |
| 19:53.25 | stefan_schmidt_ | What I have seen so far, G1, Raphael, etc they speak plain old AT |
| 19:53.45 | stefan_schmidt_ | But there seems also to be a binary protocol the modem speaks. Ever heard of it? |
| 19:53.48 | cr2 | yes, and the cdma models too |
| 19:54.07 | stefan_schmidt_ | Do they speak both? switchable? |
| 19:54.30 | cr2 | no, only AT |
| 19:54.48 | cr2 | but the companion chip is on "SBI" bus |
| 19:55.07 | cr2 | some modified spi variant |
| 19:55.22 | cr2 | but you are not supposed to talk on so lowlevel layer |
| 19:55.23 | stefan_schmidt_ | hmm, can you elaborate? Lost me :) |
| 19:56.01 | stefan_schmidt_ | ah, so lower layers are binary and they "translate" to AT on top |
| 19:56.04 | cr2 | because it's hidden from you by the "AMSS" , i.e. l4 microkernel-based OS that controls the modem DSP |
| 19:56.13 | cr2 | yes |
| 19:56.17 | stefan_schmidt_ | ok |
| 19:56.54 | cr2 | since there is no public CPU docs, you can more or less forget about it anyway |
| 19:57.14 | stefan_schmidt_ | As long as we can get AT out of it I'm happy. The rest is mickey|dinner's job. ;) |
| 19:57.36 | cr2 | the SBI bus addresses (something like i2c over spi) can be found out, but then you need the docs for the companion chips |
| 19:57.51 | stefan_schmidt_ | There is a userspace library that uses the proto. But NDA... |
| 19:58.06 | cr2 | yeah. once i've finally got umts working, he has disappeared :) |
| 19:58.09 | stefan_schmidt_ | As long as I get AT I'm fine. |
| 19:58.25 | stefan_schmidt_ | I just feared that we maybe have to re the proto, too. |
| 19:58.33 | cr2 | no |
| 19:58.41 | cr2 | at and umts data are working |
| 19:58.53 | cr2 | now we need to get rpc channel working |
| 19:58.56 | stefan_schmidt_ | cr2: He has a job last and next week. |
| 19:59.07 | cr2 | i've more or less finished the higher-level docs |
| 19:59.11 | cr2 | ok |
| 19:59.15 | stefan_schmidt_ | cr2: Should be back poking you next week. :) |
| 19:59.33 | cr2 | :) |
| 19:59.37 | stefan_schmidt_ | Were can I find them? I'm a bit lost in the xda wiki sometimes. |
| 19:59.42 | cr2 | the rpc looks like that : http://www.htc-linux.org/wiki/index.php?title=MSM_RPC |
| 20:00.01 | cr2 | the raphael data is in htc-linux wiki now. |
| 20:00.11 | cr2 | and i want to move the athena data too |
| 20:00.14 | stefan_schmidt_ | ah, I only have seen the start page on htc-linux, no link to the wiki |
| 20:00.22 | stefan_schmidt_ | ok |
| 20:00.37 | cr2 | http://www.htc-linux.org/wiki/index.php?title=Main_Page |
| 20:01.16 | stefan_schmidt_ | Now I really hope I can get the msm6281 interface working with the msm smd driver from android. |
| 20:02.20 | cr2 | hmm. don't be so sure |
| 20:02.35 | cr2 | smd driver is for the msm host cpu |
| 20:03.06 | cr2 | athena has pxa270 and talks to msm7225 (i think) over dpram |
| 20:03.28 | stefan_schmidt_ | I thought I could maybe add some glue that brings the external dual port ram into the game and use the rest from smd |
| 20:03.39 | cr2 | so it depends on how your dpram is controlled |
| 20:03.41 | stefan_schmidt_ | it's msm6xxx |
| 20:03.54 | stefan_schmidt_ | At least what I have seen at the wiki. |
| 20:04.04 | cr2 | ok |
| 20:04.11 | stefan_schmidt_ | That was the reason I asked around for Athena kernel devs |
| 20:04.15 | cr2 | btw, universal uses msm6250 |
| 20:04.26 | cr2 | but no dpram |
| 20:04.31 | stefan_schmidt_ | Already wrote mistadman a mail |
| 20:04.35 | cr2 | the umts data goes over usb |
| 20:04.54 | stefan_schmidt_ | And signaling over uart? |
| 20:05.02 | cr2 | AT cmd ? yes. |
| 20:05.06 | stefan_schmidt_ | yes |
| 20:05.08 | stefan_schmidt_ | ok |
| 20:05.21 | stefan_schmidt_ | not the same setup as omnia |
| 20:05.29 | stefan_schmidt_ | seems athena is my best bet |
| 20:05.36 | cr2 | yes, spi sounds like a pita |
| 20:06.01 | cr2 | ipaq6915 has GL chip on spi |
| 20:06.17 | cr2 | instead of uart on the moko phone. |
| 20:06.23 | stefan_schmidt_ | spi is on the eten. And the crazy part is that the modem is master and AP slave. |
| 20:06.39 | cr2 | i'm not surprised |
| 20:06.44 | stefan_schmidt_ | heh |
| 20:06.50 | cr2 | i think it's always the case |
| 20:07.17 | cr2 | on the raph too |
| 20:07.30 | stefan_schmidt_ | Well, it is strange as the normal mode is that the AP send commands to the modem |
| 20:07.50 | stefan_schmidt_ | With SPI that mean you have to trigger the modem, modem ask SPI slave (AP) |
| 20:08.03 | cr2 | ah, ok |
| 20:08.51 | stefan_schmidt_ | Sadly mistadman missed the dual port ram driver at his last commit for athena: http://github.com/mistadman/android-athena/commit/c0c0f7095dcec694fcb1c50019e5713006bdf8df |
| 20:09.06 | stefan_schmidt_ | kconfig and makefile magic is the, just the file missing |
| 20:09.15 | stefan_schmidt_ | I bet it was just a missing git add |
| 20:09.26 | cr2 | raph has a dual arm11(AP)/arm9BP) setup, and AP has much less control over the shared hardware. |
| 20:09.51 | cr2 | i will not be surprised that he does not have a working driver |
| 20:10.51 | stefan_schmidt_ | (raph) Yes, the standard msm7k SoC architecture |
| 20:11.14 | stefan_schmidt_ | (driver) You mean he perhaps did not even had a driver? |
| 20:13.05 | stefan_schmidt_ | I see you still list the omap850 devices. |
| 20:13.10 | cr2 | i think he never had a working driver. |
| 20:13.19 | stefan_schmidt_ | That reminds me that pH5 still has a dopod from me. |
| 20:13.29 | stefan_schmidt_ | cr2: oh, to bad |
| 20:13.41 | cr2 | he did some tracing, and i told him about the ba dpram driver. never heard from him anymore :) |
| 20:14.06 | stefan_schmidt_ | heh, usual foss project problem :) |
| 20:14.06 | cr2 | omap850 ? |
| 20:14.18 | cr2 | herald ? |
| 20:14.19 | stefan_schmidt_ | yup, omap850 |
| 20:14.27 | stefan_schmidt_ | DoN#t remember the name |
| 20:14.35 | cr2 | i think i've see it :) in your hands. |
| 20:14.44 | stefan_schmidt_ | It was dopod branded. Taiwan brand |
| 20:14.44 | cr2 | s/see/seen/ |
| 20:14.54 | stefan_schmidt_ | cr2: huh, when? |
| 20:14.59 | stefan_schmidt_ | We did meet? |
| 20:15.08 | cr2 | in Brussels |
| 20:15.20 | stefan_schmidt_ | hmm |
| 20:15.25 | stefan_schmidt_ | which year? |
| 20:15.38 | cr2 | you had a talk about openezx. |
| 20:15.43 | cr2 | 2006 ? |
| 20:15.45 | stefan_schmidt_ | ah, yes, that year |
| 20:15.53 | stefan_schmidt_ | should have been 2007 |
| 20:16.03 | cr2 | we also met mickey|dinner there. |
| 20:16.08 | stefan_schmidt_ | Sorry that I don't remember you. :( |
| 20:16.11 | cr2 | yes, maybe 2007 |
| 20:16.39 | stefan_schmidt_ | To many people around on conferences |
| 20:16.44 | cr2 | :) |
| 20:16.56 | stefan_schmidt_ | Will you come to LinuxTag this year? |
| 20:17.36 | cr2 | mickeyl had an pre-production openmoko phone then. |
| 20:17.53 | stefan_schmidt_ | yup, I met Sean the first time there. |
| 20:17.56 | cr2 | too far away to drive from munich. |
| 20:18.11 | stefan_schmidt_ | ah, munich is indeed a long way |
| 20:18.18 | stefan_schmidt_ | Braunschwieg -> Berlin is ok |

| 20:23.56 | cr2 | each channel has an irq, and an ack gpio |
| 20:24.12 | stefan_schmidt_ | nice clear setup |
| 20:24.51 | cr2 | chan: AT(1), DIAG(2), P1(3), P2(4), P3(5) and P9(6) |
| 20:25.10 | cr2 | i think P1 is umts data |
| 20:25.16 | cr2 | but need to check it. |
| 20:25.28 | cr2 | don't know what P2,P3 and P9 are for |
| 20:25.42 | stefan_schmidt_ | Once my device is here I need to check how similar it is to the Athena |
| 20:25.45 | cr2 | don't know about DIAG too. |
| 20:26.11 | stefan_schmidt_ | perhaps just a diagnose channel |
| 20:26.30 | cr2 | the AT can be traced very well |
| 20:26.44 | cr2 | and it operates exactly like the smd |
| 20:27.06 | cr2 | head/tail pointers for the fifos + fifos |
| 20:27.11 | stefan_schmidt_ | makes sense that quallcomm uses the same techniques |
| 20:27.25 | cr2 | yes |
| 20:27.41 | stefan_schmidt_ | That's exactly what I hoped. :) |
| 20:27.59 | cr2 | let's hope you have it the same way |
| 20:28.50 | stefan_schmidt_ | crosses fingers |
| 20:30.32 | stefan_schmidt_ | From what I can find out rigth now it seems it has 128kB dual port ram |
| 20:30.49 | stefan_schmidt_ | s/ram/sram/ |
| 20:31.29 | stefan_schmidt_ | need to find out what chip it is an if it has different parts for tx rx or just splits the ram |
| 20:32.00 | cr2 | 128k is huge |
| 20:32.25 | cr2 | msm uses 512 or 2k fifos |
| 20:33.01 | dream_kill | hi cr2 |
| 20:33.10 | dream_kill | any more progress on nand stuff? |
| 20:34.30 | cr2 | dream_kill: found the tfat32 partition. need to check if i can mount it though |
| 20:34.40 | dream_kill | cool |
| 20:34.58 | dream_kill | did u manual defined the partitions in kernel ? |
| 20:36.12 | cr2 | no, i provide them as ATAGs from haret, to simulate the g1 behaviour |
| 20:36.27 | cr2 | so i don't need to change the g1 code. |
| 20:36.47 | stefan_schmidt_ | cr2: seems to be a cypress sram module |
| 20:36.56 | stefan_schmidt_ | need to check the type and look for a spec |
| 20:37.43 | cr2 | stefan_schmidt_: usually i document the (wince) memory layout first |
| 20:38.01 | stefan_schmidt_ | cr2: Sure, I just do stuff before I have the device here. :) |
| 20:38.17 | cr2 | you have nk.exe ? |
| 20:38.25 | stefan_schmidt_ | And my girlfriend is watching a movie anyway :) |
| 20:38.31 | cr2 | LOL |
| 20:38.38 | stefan_schmidt_ | no nk.exe |
| 20:38.42 | stefan_schmidt_ | What is it? |
| 20:38.52 | cr2 | wince kernel |
| 20:39.14 | cr2 | can be dumped directly from ram |
| 20:39.42 | stefan_schmidt_ | ok, seems I have a lot to learn once the device is here |
| 20:39.44 | cr2 | usually it's exactly at the beginning of (sd)ram |
| 20:39.51 | stefan_schmidt_ | ok |
| 20:40.11 | cr2 | and it has the static allocation table at its top somewhere. |
| 20:40.37 | stefan_schmidt_ | that's good :) |
| 20:40.53 | cr2 | then you can create a table like that |
| 20:40.57 | cr2 | http://www.htc-linux.org/wiki/index.php?title=RaphaelMemoryMap |
| 20:41.09 | cr2 | the 1M entries anyway. |
| 20:41.15 | stefan_schmidt_ | cool, will do |
| 20:41.44 | cr2 | since pxa is documented, it's much easier than msm ;) |
| 20:41.45 | stefan_schmidt_ | hmm, there are only two chips from cypress that match. 128kb, 16bit width |
| 20:42.08 | cr2 | http://wiki.xda-developers.com/index.php?pagename=AthenaMemoryMap |
| 20:42.26 | cr2 | you can create such table immediately |
| 20:45.04 | stefan_schmidt_ | That is handy |
| 20:45.30 | cr2 | yes, you can already guess where is your dpram |

| 20:46.02 | stefan_schmidt_ | ok |
| 20:46.06 | cr2 | i don't know the pxa3xx memory map very well, but it should be similar |
| 20:46.18 | stefan_schmidt_ | Sounds like the first thing I will do |

| 21:08.37 | tmzt | expensive though |
| 21:09.28 | cr2 | hehe. usrp1 is like raph |
| 21:11.10 | cr2 | i'd like to know the usrp2 power consumption |
| 21:11.30 | tmzt | how is it like raph? |
| 21:11.43 | cr2 | in price |
| 21:11.43 | *** join/#htc-linux fnord_ (n=fnord@24-151-90-116.static.nwtn.ct.charter.com) |
| 21:11.52 | tmzt | ah, ok |
| 21:12.02 | tmzt | there are some less expensive dsp radio projects now |
| 21:12.39 | cr2 | ok |
| 21:14.04 | cr2 | awk '{printf("%d\n",(0x2820000+0x31f000+0x480000+0x8f60000)/2048/64)}' |
| 21:14.05 | cr2 | 1528 |
| 21:17.43 | cr2 | 321, 345, 381, 1528 |
| 21:19.16 | cr2 | the 0x31f000 is not 128K aligned |
| 21:20.12 | cr2 | hehe. it's even not 2k aligned. |
| 21:21.48 | tmzt | the partition? |
| 21:26.31 | cr2 | uh. it's too late ;) |
| 21:26.38 | cr2 | of course it's aligned. |
| 21:26.56 | cr2 | i always think in 4K pages ;) |
| 21:27.09 | cr2 | or in 8K on other hardware. |
| 21:28.53 | cr2 | but the 128K is a problem for g1 code |
| 21:29.02 | cr2 | because g1 partitions are in 128K chunks |
| 21:29.23 | tmzt | oh, in msmp? |
| 21:30.08 | cr2 | yes |
| 21:30.30 | cr2 | it's not a problem for msm partitions |
| 21:30.54 | tmzt | so we need to do something else? |
| 21:31.09 | cr2 | but you can't just declare the tfat partition in this way. |
| 21:31.26 | cr2 | well, we need to patch it for 2k blocks instead of 128k |
| 21:31.34 | tmzt | is it big enough? |
| 21:31.44 | tmzt | the field I mean |
| 21:31.51 | cr2 | int |
| 21:31.57 | tmzt | in MSMp, or whatever we end up using |
| 21:33.56 | cr2 | struct msm_ptbl_entry |
| 21:33.58 | cr2 | 41 { |
| 21:34.00 | cr2 | 42 char name[16]; |
| 21:34.01 | cr2 | 43 __u32 offset; |
| 21:34.02 | cr2 | 44 __u32 size; |
| 21:34.04 | cr2 | 45 __u32 flags; |
| 21:34.05 | cr2 | 46 |
| 21:34.13 | cr2 | 73 ptn->offset = entry->offset * 64 * 2048; |
| 21:34.15 | cr2 | 74 ptn->size = entry->size * 64 * 2048; |
| 21:34.31 | cr2 | 64 should go away |
| 21:35.08 | tmzt | but it won't be compatible with g1 then |
| 21:35.10 | cr2 | hm, and the .flags should be added |
| 21:35.16 | cr2 | yes |
| 21:35.31 | tmzt | that's what I was wondering, maybe flags could be used |
| 21:35.38 | tmzt | but the same thing, it would be different |
| 21:35.45 | tmzt | so we probably need a different TAG |
| 21:36.34 | cr2 | HTCp |
| 21:36.41 | tmzt | yeah |
| 21:36.49 | tmzt | it there a registry? |
| 21:36.56 | cr2 | no |
| 21:37.06 | cr2 | MSMp is a hack too |
| 21:37.21 | cr2 | so it's not a problem to change it,. |
| 21:37.37 | cr2 | 38 #define ATAG_MSM_PARTITION 0x4d534D70 /* MSMp */ |
| 21:38.32 | tmzt | is that literal? |
| 21:38.43 | cr2 | 128k partition block is a bad idea, imho |
| 21:38.45 | tmzt | yeah, looks like it |
| 21:38.50 | cr2 | yes, ASCII |
| 21:39.24 | cr2 | what is 43 45 ? |
| 21:39.55 | cr2 | lol |

| 21:40.12 | tmzt | where? |
| 21:40.28 | tmzt | I only saw that 4d and 4d for M and M |
| 21:40.37 | cr2 | athena smd channel uses that |
| 21:41.04 | tmzt | oh, ok |
| 21:41.11 | cr2 | awk '{printf("%c%c%c%c\n",0x4d,0x53,0x4D,0x70)}' |
| 21:41.12 | cr2 | MSMp |
| 21:41.16 | tmzt | omap csmi is also similar to those I think |
| 21:41.19 | tmzt | good |
| 21:43.18 | cr2 | tmzt: if tfat32 fat mountable ? |
| 21:47.34 | tmzt | with vfat in linux? |
| 21:47.36 | tmzt | no |
| 21:47.40 | tmzt | but it's very similar |
| 21:48.05 | tmzt | I'm going to look for some documentation on msdn about it, I did read something there |
| 21:48.42 | tmzt | it seems it has two fats that are not kept in sync but updated one at a time, each time a change is made it's made to a different fat |
| 21:50.46 | cr2 | raid1 ? |
| 21:51.57 | tmzt | not quite sure, look up "transactional fat" |
