GPSFan: HI, "fbcon=rotate:3" on the kernel command line for fbcon to start out in the correct orientation. |
| [12:17:02] |
<GPSFan> |
sweetlilmre: g'day, that's nice |
| [12:18:13] |
<GPSFan> |
I've been pokeing at the wireless, and haven't made too much progress except that I've come to the conclusion that aeronix hard coded the ssp setup into the gspi driver. there is nothing in the mainstone.c and according to all that I have seen there should be spi and ssp setup for platform specific things like which gpio is the CS and which gpio in the interrupt pin. |
| [12:18:48] |
<GPSFan> |
I put some printk's into the libertas driver and the init section is called upon insmod, but the probe section is never called. that's where the firmware is loaded. |
| [12:24:53] |
<sweetlilmre> |
well at least that is progress. is it time for IDA on the driver? |
| [12:26:43] |
<GPSFan> |
IDA ?? |
| [12:26:51] |
<sweetlilmre> |
Interactive Dissasembler |
| [12:27:08] |
<GPSFan> |
ah, maybe but it is a BIG driver... |
| [12:27:35] |
<sweetlilmre> |
perhaps the search could be narrowed to the driver init code? dunno, will have to see what IDA makes of it later. |
| [12:28:08] |
<sweetlilmre> |
GPSFan: some advice: I want to flash a kernel so that I can play with userland without have to re-xmodem every reboot. is that safe with an uploaded zimage? |
| [12:28:21] |
<GPSFan> |
I'm pokeing at the working zipit driver from 2.6.21.1 now I found that the gpio interrupt is setup in gspi8xxx.ko |
| [12:28:45] |
<GPSFan> |
sweetlilmre: the kernel may be too big at the present time, I haven't checked lately, there is only so much space in the present mtd partition. |
| [12:29:04] |
<sweetlilmre> |
I got it down to 1.5 MB which looks like it will fit into the partition (no rfs so its smaller) |
| [12:29:08] |
<GPSFan> |
I've made no real attempt to shrink it down to fit |
| [12:29:31] |
<GPSFan> |
if you have it successfully booting from mmc card then a no rfs kernel could work ok. |
| [12:29:47] |
<sweetlilmre> |
yeah the 1 GB card seems to work 100% reliably. the 2GB is totally borked. |
| [12:33:58] |
<GPSFan> |
well if you have serial access (which you must to be playing around with new kernels) and you don't overwrite blob, you should be able to recover from a bad flash. |
| [12:34:23] |
<GPSFan> |
writing the kernel (or anything else for that matter) with blob has not been tested. |
| [12:34:57] |
<sweetlilmre> |
now it has :) and it works |
| [12:34:57] |
<GPSFan> |
T0mW bricked his first Z2 by re-writing a kernel he built that he never tested (no serial at that time) |
| [12:36:23] |
<GPSFan> |
so you wrote a new kernel and it works!!! |
| [12:36:27] |
<sweetlilmre> |
yep, w000t :) only thing is missing boot parms |
| [12:36:36] |
<sweetlilmre> |
so I have to interrupt the boot and specify the mmc boot up etc |
| [12:36:48] |
<sweetlilmre> |
this is kickass :) |
| [12:36:59] |
<GPSFan> |
still that is progress. You are the first Z2 owner with an alternate kernel on board. |
| [12:37:19] |
<GPSFan> |
rats, my z2 battery ran down. |
| [12:38:11] |
<GPSFan> |
sweetlilmre: will you pastebin the console output as you flashed the new kernel? |
| [12:38:30] |
<sweetlilmre> |
now I can start fixing up the userland stuff. which will be cool. Probably get to SDL and some games, pastebin comming up |
| [12:38:49] |
<GPSFan> |
thanks |
| [12:39:02] |
<sweetlilmre> |
everything from kernel download to reboot: http://zipit.pastebin.com/m4765f61a |
| [12:43:53] |
<GPSFan> |
I'll talk to prplague tomorrow about the wireless driver, maybe he can steer me towards the proper platform setup for mainstone.c |
| [12:44:17] |
<sweetlilmre> |
awesome :) I feel a stiring in the force! |
| [12:44:43] |
<GPSFan> |
sweetlilmre: the force is certainly with you young padawan. ;>)) |
| [12:46:28] |
<GPSFan> |
cd /sys |
| [12:46:32] |
<GPSFan> |
loops ! |
| [12:46:35] |
<sweetlilmre> |
GPSFan: :) meant to ask if you have an idea of how to implement LCD and backlight on/off so that when the timeout kicks in the screen actuall switches off |
| [12:46:41] |
<sweetlilmre> |
LOL |
| [12:47:13] |
<GPSFan> |
not yet, the routines in mainstone.c don't do anything, but are called at the proper time. it should be fairly easy, but I'm focused on this wireless thing right now. |

GPSFan: fair enough, I do not want to distract you :) |
| [12:54:44] |
<GPSFan> |
sweetlilmre: are you going to try to get the boot params correct for your new kernel? |

GPSFan: yeah I just need to recompile. at the moment I am just interrupting blob |
| [13:07:07] |
<sweetlilmre> |
grr just killed inittab accidentally :( |
| [13:07:25] |
<GPSFan> |
sweetlilmre: so it should be just the kernel command line option in .config |
| [13:07:42] |
<sweetlilmre> |
yep, boot root=/dev/mmcblk0p1 rootdelay=5 console=ttyS2,115200 fbcon=rotate:3 |
| [13:07:55] |
<sweetlilmre> |
could probably take the delay down a bit |
| [13:08:21] |
<GPSFan> |
sweetlilmre: I just had an idea, could you try insmodding the original zipit gspi.ko and gspi8xxx.ko ? with the firmware parameters |
| [13:08:27] |
<GPSFan> |
with your new kernel |
| [13:08:37] |
<sweetlilmre> |
can you email them to me? I didn't extract them. |
| [13:09:00] |
<sweetlilmre> |
or are they in fatroot? |
| [13:14:09] |
<sweetlilmre> |
heh just compiled lrzsz so I should now be able to upload files (slowly) :) |
| [13:28:59] |
<sweetlilmre> |
hmm rx -X file.name works, but superfluous chars are appended to the file. still possibly and option |
| [13:33:44] |
<GPSFan> |
it looks like the gpio irq for the wireless is gpio36 |
| [13:34:21] |
<GPSFan> |
set for falling edge trigger |

GPSFan: "gspi: version magic '2.6.21.1 mod_unload ARMv5 ' should be '2.6.27.10 mod_unload ARMv5 '" |
| [13:49:33] |
<sweetlilmre> |
I will have to fudge the magic check in the kernel code to get around that. |
| [13:49:35] |
<GPSFan> |
rats... well it was worth a try |
| [13:49:55] |
<GPSFan> |
there may have been abi changes between 2.6.21 & 2.6.27 that may make it not work even if it loads. |
| [13:54:22] |

GPSFan: the OE zipit stuff is forced to OABI for the machine |
| [13:55:00] |
*** |
g1powermac_PB has joined #zipit |
| [13:57:17] |
<GPSFan> |
sweetlilmre: not EABI vs OABI, but changes in structures in the kernel headers that would make modules incompatible. |
| [13:58:44] |
<sweetlilmre> |
ah ok :) |
| [13:59:39] |
<sweetlilmre> |
hmm zmodem works well enough... now I can copy stuff back and forth. Good enough until wireless is up |
| [14:07:28] |
<sweetlilmre> |
gotta run, work tomorrow :( bleak. GPSFan, good luck with the wireless, sending maximum good karma your way |
| [14:10:01] |
<GPSFan> |
sweetlilmre: thanks, gook luck going back to work... |

rkdavis: sorry I don't have such a thing. hopefully we are not more than a week away from a working libertas_spi driver, then we get to do the whole "does it work with/support <insert your favorite wifi isssue here>" ;>) |
| [20:53:42] |
<rkdavis> |
:) |
| [20:53:46] |
<rkdavis> |
for some reason it's not seeign my ap again |
| [20:53:52] |
<rkdavis> |
did that a couple of weeks ago so trying to debug 2 unknowns at the same time |
| [20:54:01] |
<rkdavis> |
1. is my conf file screwed 2. where the hell has my ap gone :) |
| [20:54:12] |
<rkdavis> |
but you and sweet seem to be going great guns with the new kernel :) |
| [21:11:35] |
<steerpike> |

steer: i think i've got it right but the zipit seems to be not finding my ap again -- it did that a couple of weeks ago even when i'm standing right next to it |
| [21:41:16] |
<steerpike> |
rkdavis: hrm.. might want to build wpa_cli |
| [21:51:07] |
<rkdavis> |
yup -- i need to have a closer look at a lot of stuff on the zipit too -- the minisd slot seems to be getting flaky too -- kinda weird only done about 100 insertion/ejections |
| [21:51:25] |
<rkdavis> |
but that'll have to wait until tomorrow -- wife whineing in my ear about the noisy downstairs neighbours |
| [21:51:33] |
<rkdavis> |
they are playing a game at full volume and the whole place is vibraqting |
