Re: [Gumstix-users] 2.6.26 patches

Hi Terry,

I spotted the bug:

arch/arm/mach-pxa/gumstix.c:
pxa_gpio_mode(GPIO111_MMCDAT3_MD);

 -> sets GPIO pin 111 to be MMC DATA bit 3.


drivers/pcmcia/pxa2xx_gumstix.c: pxa_gpio_mode(GPIO_GUMSTIX_nSTSCHG_0_MD);

arch/arm/mach-pxa/include/mach/gumstix.h:
#ifdef CONFIG_MACH_GUMSTIX_VERDEX
:
#define GPIO_GUMSTIX_nSTSCHG_0          GPIO111_nSTSCHG_0

 -> sets GPIO pin 111 to be an input for the nSTSCHG signal.


But GPIO111 is not wired to the PCMCIA interface...


May someone verify this? I am currently working on the switch to the
2.6.31 kernel and I dont have the 2.6.26 sources and patches on the disk
anymore (I only copy-pasted here an older bug ticket in my trac account)...

Best,
Musti

[Gumstix-users] 2.6.26 patches

[Harry J Mason <hjm03r@ec...>]

Here's my attempt at 2.6.26 support in OpenEmbedded, so people can try it
out over the weekend:
http://users.ecs.soton.ac.uk/hjm03r/gumstix-oe-2.6.26.tar.bz2
(Extract under user.collection/packages)

To build 2.6.26 you'll need to add this line to your
conf/machine/gumstix-custom-<board>.conf:
PREFERRED_VERSION_gumstix-kernel = "2.6.26"

Great job. Testing them now.
Builds OK for stock Verdex config.

1st issue is with mmcroot enabled... GUMSTIX_IRQ_GPIO_nSD_DETECT not
defined. Needed to add attached patch. 

During booting there seems to be an issue with mmc. see bootlog.txt.
I have checked - it doesn't appear to be a bad uSD card.
Looks like a driver or gpio conflict somewhere around the pcmcia stuff.
Thoughts / hints?

further testing gives good results but without wireless.
on modprobe pxa2xx-cs to get wireless up - which works - the uSD card
borks on writing.
see attached bootlog1.txt (its quite long)

what has pxa2xx-cs and mmc (in kernel) got in common that is affecting
mmc?
