RE: Problems with remote debugging


Mike,

I do this all the time.  I start up insight (compiled for debug my target
processor) and load the program I want to debug into insight using file open
and select the program to debug.
I then copy the program to my NFS root drive my target is using and start
gdbserver with the following parameters.
#gdbserver tcp:2001 <prog_name>

I then connect to my target and unselect the download program add
breakpoints and any other setting I don't want to use.

A which point I set a break point in the program I'm wanting to debug and
click the run button on the insight GUI. 

The code will hit the breakpoint and I start debugging.

I use a similar process then I'm debugging using my BDM.  I have never had a
problem using either gdbserver or my BDM with insight.

Insight was the first debugger I learnt to use and I still prefer to use it
if I can.  

I don't know if this will help any and I'm using a different processor but
this is how I use insight to debug my target.
