Good to hear from you.

Thank you to you and Geert for saving me the grief of buying the wrong hardware!

The whole point of buying some mipsel hardware is to better track down a SIGSEGV I'm having with kaffe on my mipsel pda.

People on this list have suggested I use gdbserver. I've played around with it over the last month and have a feeling that it won't work.

I use busybox so its init applet can handle all the linux startup stuff I don't understand. One side effect is it starts a shell on /dev/ttyS0. No problem.

I can start gdbserver on the pda:  gdbserver /dev/ttyS0 ...

On my linux laptop, I can start gdb but, when I do:

target remote /dev/ttyS0

I never get connected to gdbserver on the pda.

I suspect its because there's alread a shell running on /dev/ttyS0. Does this sound reasonable?

Other than debugging with gdb, any suggestions as to tracking down a SIGSEGV on a pda with a shell on /dev/ttyS0?

As Geert pointed out, the big-endian SGI hardware configuration
and the little-endian PDA configuration mean that you'll be cross-compiling
for "mipsel" (MIPS endian-little) on the Indigo anyway.  SGI did
use industry-standard monitors, keyboards, and disks units of the
period (which was 10 years ago - they could be hard to find today),
but used non-standard NIC and memory cards. You're probably better
off using a Linux PC as your development host.
