Hello,
I'm debugging a firmware update problem and notice that uVison2 and 3 do not refresh the dissasembly or code memory views.
In other words, my app writes the new code into flash, but Uvision still thinks the old code is there.
Is there a way to get the latest version of uVision to refresh it's view of flash?
Thanks,
Mark
"Well, if the debugger has access to a real emulator (ICE would be nice, but JTAG might do, to), it could simply read out the ROM every time."
If it read the ROM, all it would have would be the binary executable - no symbol info! So you'd still need some way to tell it to stop using the Debug info for 'A' and switch to the debug info for 'B'...

Sometimes, that's all you need. Usually, it's better than nothing at all.
I ran into pretty much the same problem while writing a firmware upgrade function for the ADuC845 - the emulator doesn't even consider that ROM contents might change, so there's no way to check execution of an flash EEPROM write operation. I don't need symbol info - I only need to know if ROM address 0x1234 has the value 0xAB after I issue the appropriate write command.

I think it would get confusing, though, if the debugger was trying to use the symbols for image 'A' whilst looking at image 'B'...!! :-0

I would like the debugger to leave the decision on what I find confusing up to me. :)
Seriously - when debugging firmware upgrade functionality, I look at addresses, not symbols.
Thats Right!

Does Debugger do mistakes, i mean, be playful enough to off-spin ?
