Thanks for the input Georg-Johann and Johannes.
Georg-Johann: I double checked the fuses and the watchdog is not active.
Johannes: I'm not sure how I would go about doing that. But I just
read a document called "Getting started with GCC for AVR32" and found
the following:
"The linking process needs information about code and data memory
location. Using a linker script provides this. If specifying which
device you are compiling code for by using the ?-mpart=<part>? option
in avr32-gcc, a default linker script for that device will be used."
That got me thinking, maybe that's the problem, that I don't provide
the mmcu when linking. So I changed this line in the makefile:
elf:
avr-gcc example.o -o example.elf
To this:
elf:
avr-gcc -mmcu=atmega328 example.o -o example.elf
And after I compiled, linked, hexed and upload the problem was no
longer present.
With my no-existing experience I conclude that's the source of the
problem, and thus the problem is solved.
Does that make sense or is that just a coincidence that it is now
working?
