| 15:06.56 | x_bruno | hello |
| 15:07.18 | x_bruno | does anybody know the status of porting the kernel to the msm7xxx devices? |
| 15:10.08 | Zoolooc | x_bruno: you should differentiate msm7xxx, you may know that the "android" kernel is already msm7200A-"ready", which unfortunately does not yet help with msm7200 |
| 15:11.16 | x_bruno | what are the missing features? |
| 15:13.10 | Zoolooc | I'm not a kernel programming expert, but there have been discussions in this channel about this already. short version: it's not yet possible to even boot that kernel on, let's take a HTC Kaiser |
| 15:13.37 | x_bruno | Zoolooc: which is my phone |
| 15:14.15 | Zoolooc | mine too.... longer version: different initialization for several registers, vector interrupt controller, different framebuffer... |
| 15:14.17 | x_bruno | also, I downloaded haRET and I control it with pocket putty on the Kaiser |
| 15:14.31 | x_bruno | the gpio functions are missing |
| 15:14.38 | Zoolooc | you can even control it from the PC |
| 15:14.55 | Zoolooc | either via WLAN, or USB |
| 15:15.12 | x_bruno | I know, but I have a long comute |
| 15:15.48 | x_bruno | 40 minutes each way |
| 15:16.18 | x_bruno | is there any ported bootloader? like apex? |
| 15:17.37 | Zoolooc | don't know |
| 15:17.45 | x_bruno | or do we depend on the built in one? |
| 15:18.36 | Zoolooc | guess that only kicks in when some day linux is flashed to ROM. until then, I'd be happy to boot it with haret from the microSD |
| 15:19.00 | Zoolooc | which has to overcome lots of hurdles, still |
| 15:19.20 | x_bruno | you guys are using haRET for booting linux right? |
| 15:19.49 | Zoolooc | even after booting a kernel, it must support several hardware, one of them must be accessing the SD card, which will not work yet, AFAIK |
| 15:20.40 | Zoolooc | x_bruno: if I got these guys here right, that's the first approach |
| 15:23.08 | x_bruno | ok, but one of the things is: the built in bootloader supports booting from the card |
| 15:26.46 | Zoolooc | don't know, maybe |
| 15:27.11 | x_bruno | according to the xda.developers |
| 15:30.09 | x_bruno | Zoolooc: http://www.handhelds.org/moin/moin.cgi/UniversalHowtoInstallLinux |
| 15:30.26 | x_bruno | it is for the universal, but t may give some starting point |

| 16:51.17 | dcordes | hi x_bruno, Zoolooc, others |
| 16:51.24 | dcordes | I just read your conversation about kaiser |
| 16:51.35 | dcordes | x_bruno, didn't you say you are familiar with driver development? |
| 16:52.18 | dcordes | x_bruno, just to make things clear: As Zoolooc said we need no bootloader at all. Everything you can try right now can be done from haret. |
| 16:52.59 | dcordes | to say it with Kevin2's words: that would be rocket engines while we can't even walk. What we need right now is a driver for the display |
| 16:53.23 | dcordes | we can boot the msm kernel, but we can't see anything, n'either can't we get a connection because of lacking hardware |
| 16:53.58 | dcordes | that is because kaiser has a different framebuffer then the other htcs so it can't be controlled by the current msm tree (correct me if I'm wrong) |
| 16:54.36 | dcordes | have to go again, sorry |

| 18:49.33 | x_bruno | any hints on what is required for the driver? |

| 19:01.13 | kay2 | how are we gonna drive the ARM7 that takes care of the GSM protocol ? |
| 19:02.21 | x_bruno | kay2: is there any pdf with specs? |
| 19:02.46 | kay2 | not as i know |
| 19:03.14 | x_bruno | driver development is easy, as long has you have the specs and registers to pass info to |
| 19:03.45 | kay2 | yeah |
| 19:03.50 | kay2 | but its in the OMAP |
| 19:03.51 | x_bruno | i used to do gameboy advanced dev, and I did some programming in assembler for that processor |
| 19:03.57 | kay2 | both cores ARM7 and ARM9 are in the OMAP |
| 19:04.07 | kay2 | and the ARM7 has its own DSP to do the GMSK + Viterbi |
| 19:04.26 | kay2 | so as long as you dont have the datasheet of the OMAP850 u can't do anything |
| 19:04.36 | kay2 | unless you take the driver of winCE and reverse ing it |
| 19:05.16 | x_bruno | cool, its a texas instruments device |
| 19:05.21 | x_bruno | http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12000&contentId=4679 |
| 19:05.38 | cr2_ | kay2: there are no docs, and don't expect any docs. why don't you look at the typhoon gsm module ? |
| 19:05.40 | kay2 | x_bruno: but u only get the datasheet if you sign an NDA |
| 19:05.42 | kay2 | which is not easy |
| 19:05.57 | kay2 | cr2_: typhoon gsm module ? |
| 19:06.05 | cr2_ | x_bruno: all you can find on the ti site is mostly useless junk |
| 19:06.34 | kay2 | cr2_: why the typhoon gsm module ? |
| 19:06.44 | kay2 | cr2_: the source code are available ? |
| 19:07.03 | cr2_ | yes. |
| 19:07.06 | cr2_ | http://vivien.chappelier.free.fr/typhoon/gsm.html |
| 19:07.49 | kay2 | cr2_: even its GSM stack is available ? |
| 19:08.10 | cr2_ | yes, and it even half-works |
| 19:08.19 | kay2 | cr2_ ?? seriously ? |
| 19:08.37 | cr2_ | i don't have omap850 myself, so can't tell you more than you can get from this page. |
| 19:09.03 | kay2 | cr2_: what am looking for is the sourcecode of the GSM stack |
| 19:09.06 | cr2_ | kay2: from what i can deduce from the module source, it looks not bad. |
| 19:09.19 | cr2_ | GSM stack is in the firmware. |
| 19:09.20 | kay2 | cr2_: not just an AT modem |
| 19:09.36 | kay2 | cr2_: yeah but the source code of the firmware are available or its just a .bin |
| 19:09.49 | cr2_ | if you are capable to disassemble the DSP firmware... |
| 19:09.57 | cr2_ | kay2: are you joking ? |
| 19:09.58 | kay2 | cr2_: nop that would take for ever |
| 19:10.18 | kay2 | cr2_: why would I be joking ;) lol |
| 19:10.21 | cr2_ | kay2: ti does not provide even the omap datasheet. |
| 19:10.36 | cr2_ | stay away from ti if you can ;) |
| 19:11.03 | cr2_ | we will see how it will work out with qualcomm |
| 19:11.42 | kay2 | cr2_: I have the gsm stack of one of the TI gsm chip |
| 19:11.48 | x_bruno | kay2: what phone are you refering to? |
| 19:12.08 | kay2 | TMS30 |
| 19:12.22 | kay2 | tsm30 |
| 19:12.25 | cr2_ | if you have followed the openmoko development, ti prohibits the firmware update there. |
| 19:12.34 | x_bruno | ok |
