I know people using the EPI Jeeni, and I know some people have used BDM
devices.

It doesn't _need_ a console, no. (RedBoot does, but you don't need that
much in the development cycle if you have JTAG). It does have diagnostic
output (which is used as a default I/O channel in general) but that's just
output. You would probably have to add a special "NULL" diagnostic device
though, to stop the output coming out, but that's just part of a port.

There's a configuration option in the ARM HAL to enable thumb mode.
