Hi, Im back; its never too late to give up...
A atmega 8 code fairly large (2,5k hex-load) has been running smooth, from C code; however I made a major inclusion of new routines
now the machine seem not even to start; i.e. I light a led in main() more or less directly as a test output using a led that works fine
on the same pin when reverting to the version before; which makes me wonder;
what can cause a atmega8 not to start or go out into the woods before even getting into code main; as said there is no fancy in the
newly included code only some routines in C which as most advanced set i/o pins.
I dont include code here since I find it too large, and dont know where in it to start looking. Guess there must be some compile/link issue ?
