LPCXpresso Debugger

[SIZE=2][FONT=Tahoma]When debugging (with LPCXpresso 4.3.2) does it always burn to flash (assuming load = true) when internal flash is the target address even if the source code is unchanged?

This obviously wastes erase cycles and takes longer to get going. :(

Or is the debugger smart enough to compare current contents with the potential download image (constructed from the axf/elf file) and skip the pointless step.

What if one wants to flash regardless (I can't think why, but some -- perverse -- individual may want so to do).

Obviously, one can flip 'Load' on and off by hand, but this is a pain (in the ;)) and errors are just waiting to happen if you forget when the image [I]has[/I] changed.

Perhaps the 'load' configuration item should have an 'if changed' setting along with true/false.

Actually the flash "endurance" spec is 10K minumum.   The "typical" is 100K.

I don't think the number of erase cycles is a problem - these devices are validated to something like 100k cycles. Assuming the lower limit, that would allow for 1 reflash every minute for 70 days (assuming you  do this every minute for 24 hours a day. 7 days a week etc)). In practice, I don't think you are likely to reach the limit...

So I'd have to buy a new board after two months and a bit?:eek:
At least I'd get some sleep waiting for it to arrive.:cool:
