Posted on November 21, 2011 at 22:06Hello,
I have a very big problem. I have change the code and then when I make the board warm to 40�C..60�C, the processor make a reset.
If I revert my change, then I can warm up the procoessor like coocing and no reset is coming.
I have find the line:
Work well:
return((UINT16)((tempCount32+2) / 4));
Work not:
return((UINT16)((tempCount32+2) >> 2));
But: the processor do not jump into this line!!!
Then I want look about the assembler code, but when I add in the makefile:
-Wa,-ahlms=$(addprefix $(OBJDIR), $(<:.c=.lst))
then the processor make a reset after warm up, without change vom code!
I have no idea what I have make wrong.
Compiler: Coudesourdery, -O1
After temperatur reset, in the register RCC->CSR, the upper 8 bit have ''0x14'', look like SW-Reset, no Watchdog!
After this reset, the processor start and work for some ms and make a reset again until the chip is cold.
I have test it with a lot of Boards an three PC's.
Please, help me!
My guess
is
that the
debug
unit
reset
the processor,
because
the Status-Register RCC->CSR look like the same when I download a new program by JTAG.
