JTAG Connect Problems

2004-02-04 by Bill Knight

I've been ignoring this problem for too long.  It's time to
determine if everyone has experienced it or if it is something I'm
doing.
  I'm using gcc, gdb/Insight, and Macraigor's Wiggler & OcdLibRemote
to build and debug programs running from RAM on a Nohau LPC210x TESTER
Board.  A majority of times when I try to connect to the LPC via
OcdLibRemote from gdb/Insight, OcdLibRemote reports "Cable
Disconnected" and gdb/ Insight does not connect.  Additional attempts
to connect to the same OcdLibRemote session fail within gdb/Insight
even though OcdLibRemote reports success.  The whole thing will
eventually connect after multiple attempts of exiting both
OcdLibRemote & gdb/Insight, and various pressings of the RESET button
on the Nohau board.
  Another issue I remember while writing this is that once connected
and debugging with Insight, it is possible to step through and debug C
source code but not possible to view the underlying assembly code.
  Both of these problems exist for multiple versions of gcc and gdb/
Insight.  So for both issues, has anyone else had either problem and
importantly, have they been able to find a resolution?

Thanks for any suggestions and help you may provide.
