Compiling a Linux 2.6.13 kernel I can see that it does not use the -mcpu
option, only the -march=armv4 option and -mtune=strongarm1100 option.
That seems to resolve this issue.

The kernel also specifies the -mno-thumb-interwork option which seems to
resolve this problem.

My kernel boots and mounts a root FS over NFS from my host. On the host
I have just compiled BusyBox (1.0) which I would expect to see run.
Unfortunately after the kernel displays "Freeing init memory: 100K" I
see nothing else displayed.

I can still ping the Jornada though!

So I think the kernel has compiled OK but maybe not busybox.

Has anyone built Busybox with the CodeSourcery compilers for the Jornada?
