Working Custom Kernel - What Am I Doing Wrong?

[Scott Miller]

I am trying build my own kernel for the Pandaboard ES. I have tried multiple configurations and kernel versions with the same result. Every kernel that I build stops booting immediately after "Uncompressing Linux... done, booting the kernel." The following are a few of the examples that I have followed TO THE LETTER:

• http://omappedia.org/wiki/OMAP_Ubuntu_Core#Kernel_and_Bootloaders.2C_do_it_yourself_instead_of_using_prebuilt_binaries - I have tried this with exactly what is there and with newer versions of U-Boot and the Kernel.
  
• http://elinux.org/Panda_How_to_kernel_3_3_rel with the U-Boot and MLO created via http://elinux.org/PandaBoard_ES_uboot_howto

I have also pulled the latest Ubuntu 12.04 kernel sources and built using the configuration that is in the boot directory of the latest Pandaboard 12.04 image.

I get the same result with EVERY single kernel that I build.  I have even used the prebuilt Ubuntu kernel and the Pandaboard validation kernel with my U-Boot and MLO and they both worked correctly.

What am I doing wrong when I build my kernel? Is there some extra step I need? I just "configure" (or use and existing configuration) and "make" (with the correct ARCH and CROSS_COMPILE) and then copy to the SD card's boot partition right? Same as a Beagleboard, right? Would using a different cross compiler work? I'm currently using one created with OpenEmbedded.

hi,

try this tutorial

http://morschi.com/2011/11/13/up-to-date-kernel-for-pandaboard/

you have to make sure that the needed modules are either built-in or use initrd, i have a pandaboard (not ES), but this works for me.
