Yes -- I've got a hardware timer that I use to generate 10ms
interrupts, and I can use that.  I haven't so far: none of my
eCos apps use a busy-wait microsecond delay routine, so I had
never had one until I added RedBoot to the picture.

I thought maybe I could assign one IP address to the console
interface (and my other TCP stuff) and a second one to the GDB
stubs.  If not, I'll concentrate on trying to get serial
debugging working.  If they find serial too slow, then I'll
tell them to buy a JTAG interface.

It's serial or JTAG then.  ;)
