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.
