Hi all,

I've been hacking my E3 over the last few days, but I can't seem to get my rootfs image to work...

My toolchain seems to work, as I can compile u-boot and the kernel with no problems, and they both boot, but the root just doesn't want to execute - i.e it stops after :

"... RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem). Freeing init memory: 100K"

I've checked my inittab, and the relevant line is there:

"::respawn:/bin/ash"

I've mounted the ext2 image locally, and 'file busybox' says:

"busybox: setuid ELF 32-bit LSB executable, ARM, version 1 (ARM), dynamically linked (uses shared libs), stripped"

So I know that its compiled correctly. (unless I require static linking)

I'm using the standard linux.pbl pbltool script, so maybe I'm getting the memory locations wrong (my rootfs and kernel are slightly different sizes)

When using the stock rootfs, the system works fine with my u-boot and kernel.

Any help would be appreciated,

Hi Tolly,

Did you use the configs in the release? These should work fine. It required a fair amount of trail and error to get a buildroot & busybox configuration that worked and I'm really not sure why :-/. You will also have to stop the rc scripts from running (they don't work), it's best if you just copy the inittab from the release over your version.

As for the memory layout, as long as your kernel is under 2M (compressed) and your rootfs is under 1M (compressed) you should be fine. If your rootfs is bigger then 1M then you will have to move it up a bit, althought you would know about it as you would have over-written the kernels u-boot header and it would refuse to boot.
