[Gumstix-users] kernel panic - no init found

[Joshua Warren Priestley]

I searched the archives for this problem, but I couldn't seem to find any solutions. I recently reflashed the linux system on my gumstix, and when I boot the kernel, I hit a "Kernel panic - not syncing: No init found. Try passing init= option to kernel" error. Currently my bootargs environment variable is "console=ttyS0,115200n8 root=1f01 rootfstype=jffs2" however I've tried appending " init=/sbin/init" and " init=/bin/sh", which were two init parameters I was able to find on the u-boot page. Both of these result in a "Failed to execute <filename>. Attempting defaults..." error, followed by the same kernel panic message. The new linux image is version 2.6.15.

Does anyone know why I'm getting this error?

Sounds like something is wonky with the file system. Do you have an XM
card? Did you erase all of memory before downloading (and not just the
firt 4 Mb)?

In your buildroot, what do you see in the build_arm_nofpu/root
directory? (check in bin to make sure that there is an sh and that
busybox also exists. sh should be soft-linked to busybox.

I believe I did erase all the memory before flashing. Here is the list of commands I used to do the reflashing:

mmcinit
protect off all
protect on 1:0-1
fatload mmc 1 a2000000 rootfs_arm_nofpu.jffs2
erase all
cp.b a2000000 40000 ${filesize}



I checked in the build_arm_nofpu/root/bin directory, and there are only two executables: busybox and lsmod. Do you have any idea why this is? Could I simply use subversion to redownload the latest buildroot and try again?

Come to think of it, when making the kernel image (typing make from gumstix buildroot after cross-compiling from linux-2.6.15gum) the last message is "hostname: Host name lookup failure" when defining the BUILD_HOSTNAME variable. Do you suppose that this jffs2 image has not been created successfully?

That's the problem then. Somewhere in the buildroot it creates all of
the symlinks to busybox and it looks like your build failed.

You could re-download. I know I'm using 1008 and it seems to work fine.

You could also just remove build_arm_no_fpu and toolchain_arm_nofpu
and try the make defconfig & make again.

Something is obivously wrong since your root/bin directory should have
about 50 files in it.
