Adding a target?

["Edward L. Hepler" <hepler at vlsi-concepts dot com>]

Thanks for a very nice tool.

I have developed a synthesizable embedded controller based on the MIPS 
r2000 instruction set.   It includes a JTAG port that interfaces to 
logic in the core that permits debugging (via observability and 
controllability of registers, memory, etc.).

I have modified GDB by adding a new target (as part of remote-mips.c) to
accomodate the JTAG port (and also allow GDB to act as a front-end to
drive the VHDL RTL model embedded in a design simulating in Modelsim).

I'd like to use insight to drive gdb and have included the appropriate
gdb modifications.   The "gdb-side" appears to operate properly, but
I'm still having some problems with the GUI portion.  I'd appreciate
any pointers you may be able to send that would help in adding a target
to the GUI...    An error pops up stating that "can't read 
"PREFS_state(gdb/load/default-portname value)" no such element in array"

I do have experience in writing Tcl/Tk applications, so some general
pointers may be enough...

Many thanks,

Ed Hepler

P.S.  I'm using insight-6.6  (I downloaded insight-6.7.1, but "configure"
failed due to syntax errors (lines 11 and 19)...  Haven't had time to 
look into this...).  I'm also running all of this under Cygwin
on a PC running Windows XP pro...
