Here is where I am. User space code (busybox) was compiled
using the unicore toolchain available on the web.

...

Enable UniCore-F64 support.
Warning: unable to open an initial console.
Freeing unused kernel memory: 1156K (c0408000 - c0529000)

Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

The kernel tries to execute the init program, which fails with SIGSEGV.
I confirmed that the init program is loaded and starts to execute.

Any idea what might cause such a problem ?

Thanks,
Guenter
