08:43.13alex[slx]Hi guys. I've got OpenMoko on my O2 Xda II mini (aka magician) and I've run into a problem. When I shut down the device (not locking, shutting down) it seems to hang. Then I do a soft reset (stylus in the hole) and I can't turn it on again without a hard reset.
08:43.29alex[slx]Am I missing something, or is this common behaviour?
08:46.49cr2alex[slx]: it's normal
09:00.14alex[slx]cr2, Ok. I guess I just won't shut it down then.
09:01.47alex[slx]cr2, Also, do you know if that happen on the Neos (the OpenMoko supported hardware)?
09:02.09Marexcr2, hi, long time no blackmailing ;
09:02.11Marex;)
09:23.22alex[slx]Hmmm... seems that `date` kills it too.
09:23.41alex[slx]No, just locks it.

20:21.54cr2hi miknix
20:25.09miknixhey cr2
20:26.07miknixcr2, a guy with kernel hacking experience just pinged linwizard
20:26.24miknixhe is looking for a good device to work on
20:27.01cr2good is subjective
20:27.24miknixhe is considering to buy the HTC S710 which is known to boot the linwizard kernel
20:27.47miknixcr2, "good" as "well supported"
20:28.03miknixbalajirrao, still around=
20:28.05miknix?
20:28.51balajirraomiknix: yep!
20:29.26balajirraoso thumbs up to HTC S710 ?
20:30.02miknixbalajirrao, cr2 is who knows better about HTCs
20:31.03cr2balajirrao: it's more about the optical look, functions and ... the main cpu.
20:31.45balajirraocr2: ok.. which one would you recomment if I need to hack around with linwizard ?
20:32.19miknixbalajirrao, no need of linwizard.. we all want linux on HTCs here
20:32.51balajirraomiknix: ok! :)
20:32.54cr2imho, the best (and probably the most expensive) omap850 phone is artemis
20:33.07balajirraocr2: ok. will look at it
20:33.19cr2but the phone is a bit pita on omap850 devices.
20:33.30*** join/#htc-linux infernixx (n=nix@unaffiliated/infernix)
20:33.49cr2there are a lot of factors you'd take into account actually.
20:33.55miknixcr2, does artemis use the same driver as wizard for the phone?
20:34.03balajirraocr2: ok. omap850 devices as in ?
20:35.15cr2balajirrao: the main difference between the phones is the cpu.
20:35.41balajirraocr2: oh.. ok..
20:39.31balajirraocr2: considering all the factors, would you recommend a S710 ?
20:42.18miknixbalajirrao,  http://wiki.xda-developers.com/index.php?pagename=HTC_Vox
20:45.18cr2balajirrao: i have 6 htc phones, and noone works 100%
20:45.18balajirraomiknix: cool. thank you for the link
20:45.40balajirraocr2: ooh! ok.

21:48.31SmallR2882would an LTE network support an older GSM phone?

21:54.07cr2SmallR2002: what is LTE network ?
21:56.03cr2ok, found it.
21:56.43cr2Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, should coverage be unavailable, continue the operation without any action on their part using GSM/GPRS or W-CDMA-based UMTS or even 3GPP2 networks such as CDMA or EV-DO)
22:06.50gingeAnyone here know about hacking Android kernel on the Kaiser?
22:09.08gingeBasically I need to get to a console prompt from Android so I can read the touchscreen calibration info off
22:10.36SmallR2882cr2, so that would be a yes?
22:10.39SmallR2882see
22:10.50SmallR2882i'm used to a europian phone service
22:11.18SmallR2882the whole cdma/gsm thing never came up before
22:11.25SmallR2882now i'm in the states it's a big issue
22:12.39gingeis an on screen keyboard on the Kaiser anything of value to anyone?
22:12.52ginge(on Android)
22:12.53martin__Um, we have a real one?
22:13.28martin__ginge: I'm working on the kernel for kaiser.
22:13.36gingetrue, but I have some buttons on it mapped to debugging tools at the moment. Could be handy
22:13.58gingehey, maybe its you keyboard I just patched it :)
22:14.07gingeyou do the vogue too?
22:14.13martin__No, different Martin :)
22:14.21gingeheh
22:14.22martin__Martin Johnson is dzo on here.
22:15.21gingeah, pretty new to this scene. I just spent a few hours getting the build tools together, and working out why the shift functions don't work in the (real) keyboard driver. Do you have any handles on that?
22:15.49martin__I've not looked at the keyboard stuff
22:15.55martin__It was working before I got involved.
22:16.10martin__I'm trying to get write access to the shared memory devices working.
22:16.22gingemaybe I'm missing something obvious. Oh? for the data access?
22:17.19martin__The modem, primarily.
22:18.06gingeyeah, so is there a way of dropping to the console from Android?
22:18.06martin__We can read from the modem, and the GPS, but can't currently write properly.
22:18.57martin__ginge: I dunno about the android image, I'm just using a minimal console initrd.
22:19.04martin__http://linuxtogo.org/~lgorris/kaiser/angstrom-consle-image.cpio.gz
22:19.15SmallR2882martin__, could you update the information on linux-gps.org about it's gps?
22:19.46gingeCheers, I was going to roll my own but you saved me the trouble
22:20.50gingeDoes serial console access or ssh over tcp work?
22:21.36SmallR2882i've been trying to get linux-gps.org to be a database of gps devices and their support
22:21.42SmallR2882unfortunately i don't have much time
22:21.49SmallR2882or many gps devices :p
22:22.23martin__SmallR2882: It's not really "working" on kaiser yet. If it's turned on in wince then we can read the stream in linux after boot, but that's some experimental code that's not even in a git repo yet.
22:22.53martin__ginge: No. We've got no comms at all.
22:23.21SmallR2882i don't think there's any info on there at all yet mate
22:23.30SmallR2882i could use any support at all with that project
22:24.03martin__SmallR2882: http://void.printf.net/~martin/kaiser-smd.c
22:24.06martin__that's all there is
22:24.10cr2SmallR2882: builtin sirf3 usually works ok.
22:24.58martin__and it's of zero use to anyone until a lot more of the kaiser works
22:27.47martin__ginge: if you want a project, I can get you started on debugging the bluetooth
22:28.15martin__that may be the easiest way of getting some remote access to the device
22:28.28gingemartin__: sounds good. Now I have the screen calibrated I need something to get my teeth into
22:29.05martin__ginge: okay, are you all set up with a toolchain and the git repository?
22:29.31gingemartin__: yes, both vanilla android and htc-msm
22:29.53martin__okay, you want the htc-msm branch for this.
22:30.14martin__You're looking at drivers/serial/msm_serial.c
22:30.18SmallR2882cr2, ok, if you have a chance it'd be good if you could add a list of 'should work' ones
22:31.18gingeokay, I see it
22:31.29cr2SmallR2882: n560 works, and artemis works. athena should work too. after i'll add the power gpios ;)
22:31.43martin__ginge: msm_serial is a driver for the on-chip UARTs of the MSM7500A, and it works on the Halibut dev boards that the android developers use.
22:32.02martin__The Kaiser is an MSM7200 so there will be some differences.
22:32.20martin__The bluetooth on the Kaiser is connected to UART1.
22:33.06martin__If we can get the UART working, I think I can get the bluetooth chip going.
22:33.18martin__Currently, the serial code hangs at init.
22:33.56gingemartin__: Ok. I iwll look it over.
22:35.08martin__ginge: At the moment, this driver is built in with the kaiser defconfig.
22:35.46martin__But in arch/arm/mach-msm/board-htckaiser.c, the device is commented out from the list of platform devices.
22:36.20martin__(line 284)
22:36.42martin__Uncomment that, and your kernel will hang on boot.
22:37.01martin__If you boot with the initcall_debug option, you'll see that the hang comes at the msm_serial_init call.
22:37.11martin__Now, here's the wacky thing:
22:37.44martin__If you put a printk at the start of msm_serial_init, you will see the first one or two characters of it on the screen before the hang.
22:38.37martin__This doesn't mean the printk is hanging half way through. It means the code's getting further than that, but locking up the whole system before the framebuffer has got round to drawing the text that's already been printk'd.
22:39.20martin__So what you really need is a function that prints something and then runs a delay loop for a while to give it time to get to the screen.
22:39.56martin__Then, armed with this function, sprinkle the code with debug until you find out exactly what line causes the hang.
22:40.27martin__Once we know that, we'll have a better clue what we need to change.
22:40.49martin__ginge: good luck! /msg me if you need to know anything else.
22:40.57gingemartin__: Ok. Thanks!
22:42.51martin__ginge: the other person on here working on the kaiser is dcordes
22:43.23martin__I threw this one at him too, he might have got somewhere, so have a chat with him if you see him around.
22:44.28gingeok sounds good. Reminds me of the old days porting Linux to my jornada 928. I seem to remember saying never ever ever again ;)
