[U-Boot-Users] BDI2000 problems flashing virgin custom 8548 board

[Chris Fester]

I had the same problem with an mpc8641.  After emailing the Abatron
folks they set me straight.

There's probably a line in your bdi config file like this:

WORKSPACE   0x00002000                  ;workspace in SDRAM

Comment that out.  The BDI uses a little chunk of the processor's RAM to
speed up flashing and whatnot if you include that line.  But if you
don't have a valid RAM configuration then you're going to get workspace
errors.  The BDI will still be able to work without the workspace RAM,
it's just slower.

Hope that helps,
Chris Fester
