watchpoint difficulties

crez — Sat, 04 Apr 2009 05:41:28 GMT

I am using full chip simulation on version 6.7 build 8127. Whenever I set a watchpoint, I get the message "not all watchpoints can be set". I am new at this, so It's probably a silly mistake on my part. What am I doing wrong? Device : hc908jl3

Hello

For watchpoints to be functional while debugging on hardware you need to have 2 hardware breakpoints available on chip.

As far as I know there is not enough hardware breakpoint on the HC08JL3 MCU. So you cannot use watchpoint on this hardware.

Thanks,

That would make sense if I was running the code in hardware, but I thought that the limitation you mention would not apply when running a full chip simulation.

Hello

Then it seems that the simulator is using simulated hardware Breakpoints registers to handle watchpoints.

I would recommend you to submit a service request to validate that this is really what is going on and to submit a Change Request to get an extension in today's simulator.
