Re: Accessing Wiggler from Linux GDB

[Daris A Nevil <dnevil at snmc dot com>]

I would certainly be interested in using a PowerPC wiggler directly from Linux.
I am currently using the EST "wiggler" and Windows based debugger on a
custom MPC850 board running Linux.  The drawback is, however, that I
can only effectivly debug my boot code.  Once I hit the virtual memory
environment of Linux I loose the ability to control the different regions of
memory.
