Aura H2O Compile and run own kernel

[sahbi]

I am trying to compile and run my own kernel for the h2o, compilation is successfull except some warnings, but I fail when trying to boot with the new kernel, the power button led gets on and that´s it, until I turn it off. I am using the toolchain kernel and config from kobolabs. Am I missing something? is there any extra steps I overlooked? please help.

You'll need to build an uImage for uboot, not a bzImage.

The led its on and not blinking? This means your kernel isn't loaded yet.

You could look here: https://github.com/pazos/linux-2.6.35.3-kobo and see my commits for a working example for the Kobo Aura HD. The only thing missing from stock sources is the wifi driver.

ie: building the kernel you'll need `make uImage modules`

Thanks pazos for the help, yes indeed I´m using the make uImage make target, or the other way, I´m using mkimage and the zImage, the kernel seems fine, and then use dd to write it to address 100000, but as said it´s not booting.

The led its on and not blinking? This means your kernel isn't loaded yet

or maybe it`s crashing or simply hanging in the middle of the boot phase, due to a bad config, has anybody succeeded on the aura h2o to get a running custom kernel already?

Ok, good to know.

Please check your kernel config. The stock config isn't good at all. You need to look for CONFIG_CMDLINE option. Please remove this option because anything there will override the cmdline passed to the kernel from uboot. (ie: in my aura HD the rootfs=/dev/mtdblock2, which does not exists)
