I don't know. You can also build coff format executables using the
Gnu toolchain if that helps.
Gdb does support the RDI protocol used to talk to JTAG interface boxes
for the ARM. I've used gdb with the ARM Embedded ICE and the EPI
Jeeni. The latter has an ethernet port, so downloading is way faster.
I've submitted several patches to improve RDI support, so you should
either get GDB 4.18 sources and apply the patches, or you should get
the CVS snapshot of gdb (which I think has my patches merged into it
at this point)..

Don't know -- I use gdb.
