I have been using LPCXpresso on Ubuntu 14.04 for a couple of years but have hit debug problems with 8.1.2 and 8.1.4 (I did not try 8.1.0). I am using an OM13000 LPCXpresso LPC1769 board as a debug probe to my target (it is an LPC1768). The probe identifies as LPC-Link Probe v1.3 (LinkServer) on 8.1.4.

The problem is that setting breakpoints usually (not always) fails with a 'cannot access memory at...' type error. Also, reading the values of variables is very unreliable - usually you just get nothing. After a few (sometimes just one) single steps with the debugger, I end up with the debugger stopping with : No source available for "0xffffffff" in the code window and "Program received signal SIGSTOP, Stopped (signal). 0xffffffff in ?? ()" in the console.

Going back to LPCXpresso 8.0.0 I have no issues what so ever. The debug probe identifies as LPC-Link v1.1 LPC-Link Driver linux32 v1.1 and debugging works fine.

For now I can just use 8.0.0 (as I have both versions installed) but it would be nice to be able to use the latest version.

Any ideas ? Thanks.
