I have successfully installed Chrubuntu 13.04 (kernel version 3.4) on samsung Chromebook Exynos5 with ARM coretex-A15. And I also tried to update the kernel version to 3.9 by downloading new kernel, compiling and installing. However, with successful installation(all required kernel img files in /boot directory were generated), after rebooting it, the kernel is still old version 3.4.

I compiled the kernel in Chromebook without cross-compile and ran default gcc in Chrubuntu 13.04. Is there any thing I missed during compiling new kernel? As I heard, there's no "grub" in arm linux, is that a problem? If somebody can pin point the problem or provide the solution to update the kernel, pls help me.

This question came from our site for professional and enthusiast programmers.

  • Did you try make install? Typically /bin/installkernel is the system location; but I don't know about a ChromeBook. – artless noise Jun 3 '13 at 23:06

You are correct in that Grub is not (yet) supported on the Chromebook.

Alternatively, you can use a chain-loaded U-boot: http://www.chromium.org/chromium-os/u-boot-porting-guide/using-nv-u-boot-on-the-samsung-arm-chromebook
