[ECOS] FADS823

Hi,

is it possible to get eCos running in MPC8xxFADS evaluation board with
MPC823? In supported targets webpage there is MPC8xxFADS with MPC860,
but not with MPC823.

It should be possible. The CPUs are very similar. Note however, that
the FADS is an unsupported board. We don't have one at Cygnus and
haven't tested the port.

See the hal/powerpc/fads/<version>/README for details.

Cheers,
Jesper

I worked with the fads for a while.  I recommend using the
ADI card if at all possible.  I had no end of trouble with
"BDM" debuggers and the FADS.

If you want to ROM your application, you'll have to make up some
startup code and insert it in hal_hardware_init in the file,

  packages/hal/powerpc/fads/v1_2_x/src/fads.S 

You might find the MBX 821 code a good reference,
  packages/hal/powerpc/mbx/v1_2_x/src/mbx.S 

But note that the cache size is different on the 823.
