µVISION DEBUGGER: SETTING BREAKPOINTS ON IDATA MEMORY


Information in this article applies to:

  • µVision Version 2.05

QUESTION

I'm creating an 8051 program using µVision and C51 V6. I can't seem to set a write breakpoint on I:0xFF in the debugger in µVision. I've tried many combinations of...

bs write i:0xFF

to detect the following assignment:

unsigned char idata *p = (unsigned char idata *) 0xFF;

*p = 34;

but nothing seems to work.

Can you tell me how to do this?

ANSWER

We have confirmed this to be a problem in µVision V2.05 and earlier. It will be corrected in V2.06. You may download the latest updates from the following URL:
