Okay, I managed to cross-compile kernel-1.1.
(Unfortunately the original kernel-1.1. built process does not support 
cross-platform builts, distinguishing between host and target):
1. Build the kernel & dictionary on my host system (cygwin)
2. Build the target kernel (Leon-Sparc) including the dictionary.h built 
in step 1.

After starting openbios() I'm getting the error:
    panic: dictionary not valid.
load_dictionary() returns -1;

Could this have to do with endianess ? Some other ideas ?

The system itself seems to be quite small:
Uncompressed: 26 kB code + 24 kB data
Compressed: 11 kB code + 10 kB data


Thanks & regards,
Rolf.
