GRUB(2) on ARM

[knawnd]

Hi!

According to that web-page it should be possible to run GRUB on ARM SoC (work on GRUB2 is in progress).
I wonder if anyone has tried that? Do I understand right that having GRUB(2) on ARM SoC would let to avoid the necessity of flashing linux kernel (into recovery or kernel partition) and allow to boot in new kernel from sdcard by just modifying GRUB(2) command lines as it can be done on x86(_64) machines?

Depends as it is SOC dependent so for running GRUB from uboot in Rockchip terms would mean running GRUB from RK3188Loader(L)_V?.bin which is Rockchip's uboot binary. But as the Rockchip uboot source is proprietary and closed you're stuck with booting as defined by Rockchip for the time being. Rockchip's new 3.10 kernel will at least give FDT support (see http://www.freaktab.com/showthread.p...188-and-RK3288).

Recently I built a kernel with rootfs >http://speedy.sh/gArnd/boot.img.xz
which contains kexec + petitboot, kexec works petitboot without gui also works but does not boot new kernel
the error message kexec - "unrecoverable error: could not scan" / proc / device-tree / ': No such file or directory "

the problem is with the kernel source is missing dts.
