Re: Can program but not debug
Well, just like my previous PK4 issues, it started working again all on its own.
Initially I was programming (successfully) and then immediately trying to debug.
The final step, as reported in my OP was to program the target, disconnected the PK4, checked the app was running correctly (e.g. CAN bit rate as mentioned). I didn't initially try debugging again after this.
Now it will debug.
@Jim Nickersen Thanks, but I haven't changed any config bits between working, not working.
