Hi All

 

First of all thanks to Thomas and Joe. With your help I was able to go one step forward. However still I could not succeed in booting. I am pasting below what was the response this time.

 

After this the console was hung. Again I need your kind advice.

See below for comments.

Hopefully someone with a MVME230x can provide more help
but I think I can guide you in the direction of where things
are going astray.

Thanks and Regards

Zia

Unknown motorola board Please update libbsp/powerpc/shared/motorola/motorola.c

These last three lines indicate the first level of the problem
and the file to fix.  Apparently this file does not recognize the
cpu_type and base_mode versions. 

Looking in the file, I see this entry in the table of known boards
which based on the code which matches I think should produce
a match

  {0x1E0, 0xF9, PPC_604,     "MVME 2300", mvme23xx_intmap, prep_pci_swizzle},

You may want to sprinkle getMotorolaBoard() with some diagnostics
and see why it isn't matching.  If it matched, then it should be OK.

Since it doesn't manage to match the known list of boards,
it doesn't know what to do.

At this point, it locks up.
