The closest eCos supports is the Motorola MBX860 or MBX821 boards. I
understand the MPC821 is similar to the 823, but I'm not sure exactly how
much.

eCos does not support debugging other than by GDB, so you are on your own.
You can talk to the board using serial, or over the network for boards
with  PowerQUICC ethernet. From what I can tell, neither the MPC821 nor 823
have PowerQUICC?
