Sorry for ressurect this old Post!
I didn't use my Hannspad since an year now. Some weeks ago I decided to change this situation by installing an other system on it.
I decided to use a mer based plasma active system and maybe later sailfish os beacuse it is also mer based. With using the v5 kernel from imayoda, I managed to boot my system from sdcard.
But in fact 3D driver is missing and I have to use fbdev in X, the system is unusable.
So I tried now for several days to compile my own kernel for this. Since kernel 3.10 there is Tegra2 support in mainline kernel. Actually I use kernel 3.13.
But I don't get my system to boot. I tried to unpack bootv5.img and repack it with my own kernel zImage, but it only works with original zImage. I'am using "mkbootimg" and "unmkbootimg" for this task.
I have already tried it with an old Tegra4Linux kernel, but the same problem. I also tried to use same config for this with old kernel.
I used gentoo since years know and also on different other arm devices (raspberry-pi, odroid-u3). Because of this configuring and compiling a kernel ist not that hard task for me.
I tried to crosscompile it on my gentoo 64bit machine and I also tried it natively on my odroid but it doesn't boot.
I think I miss something essential and I hope somebody can help me...i'm not very familiar with the tegra stuff.
@imayoda (or anybody else):
can you provide me a guide how you manged to compile your kernel an packed it to a boot.img?
I realized that your ramdisk ist empty?!?
I would appreciate for any help!
