Hi,
here are some tests results of 13.1 images. Results are pretty bad ATM. :(

The USB problem seems to be known: http://www.spinics.net/lists/linux-omap/msg90670.html Is boot problem related? I do not know.
D6 and D7 lights (related to MMC) are turned OFF when kernel start whereas it was ON with u-boot. So, MMC seems to be not working at all. It seems that kernel modules (at least omap mmc modules) from initrd are not loaded. Very strange. If you boot with kiwidebug=1 you should be able to get a shell and check whether the modules are loaded or not. Indeed, mmc modules are not loaded. But loading them manually does not help to get mmc device to appear. I think we are missing other drivers (maybe GPIO). Could you quickly compare the defconfig for omap4 and the one we have to see what we're missing? I think it is missing from initrd only, not rootfs, since initrd has only some of kernel modules. I will try to add some kernel modules to our initrd and see if it helps. I added '<file name="drivers/gpio/*"/>' to driver list in kiwi since MMC0 uses TWL4030 GPIOs and now MMC is tried to be detected but fails:

The main problem seems to be: "twl4030_gpio: can't dispatch IRQs from modules"
and as said here: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/085111.h... "twl4030_gpio: can't dispatch IRQs from modules ... apparently because there is no way to unregister a irq once the module is unloaded.
That makes sdmmc pretty much unusable if twl gpio is built as a module."
I will try to add more kernel drivers but I think we should have TWL4030 GPIO built-in and not as a module.
Adding TWL4030 gpio as built-in instead of module does help to boot on MMC. What would be the best way to add this patch? I would say: * Adding kernel-default (and kernel-source?) to 13.1:Ports to fix current version * Adding it to 13.1/master GIT repo for futur versions Guillaume -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
