porting existing HP-UX to Linux

[Steve deRosier]

Jan,

I recently had a project where we were moving code done with the MRI tools
to the GNU tools.  We have custom boards all using the 68k and Coldfire
series chips.  Our pilot project was only done on boards with the 68332
chips, but this may have some value to you. The emulators we use are also HP
Emulator series 64700.  I never tried to get GDB working with it, but we use
the HP graphical debugger/emulator interface with it, running on a HP
workstation.  Anyway, a reprint of an earlier answer by me:

This may help you get up and running at least with the HP software for your
emulator.  Don't know if this helps, but...

Good luck,
