Problem building Linux kernel; Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

Hi,

I'm trying to rebuild the TI Linux 3.2.0 kernel for a BeagleBone. I have the ti-sdk-am335x-evm-05.05.01.00 SDK installed.

First question; which tree should I be building from:

ti-sdk-am335x-evm-05.05.01.00/board-support/board-port-labs/sitara-board-port-linux

ti-sdk-am335x-evm-05.05.01.00/board-support/linux-3.2.0-psp04.06.00.08.sdk? What is the exact difference between these two directories?

For my test I used the source in ti-sdk-am335x-evm-05.05.01.00/board-support/linux-3.2.0-psp04.06.00.08.sdk.

I used the steps shown in http://pastebin.com/5BCBHDC3 to build the kernel. The only modification I made in the menuconfig was compiling in ext4 support (not as a module), as my rootfs is ext4 debian 6.0. The .config file used is at http://pastebin.com/eWAFEubk

After copying the files over and rebooting the BeagleBone I get these messages on startup, looks to me like it can't mount the root filesystem:

The message "request_module: runaway loop modprobe binfmt-464c" may be a clue.

Can anyone please tell my why this kernel is not booting and how to get it to work?

My cross compiler is the one from the TI-SDK, i.e. arm-arago-linux-gnueabi-gcc (GCC) 4.5.3 20110311 (prerelease)

Thank you,

Sean

These errors means the kernel is not able to find the initial boot device or required filesystem on the boo media.Can you try a initrd or initramfs image or if possible an nfs
