My CPU enters Abort Mode after using printf inside IRQ.
I should mention that there are two interrupt sources in my system: First is the FIQ. It has the high priority. It's triggered by Timer1 up to 200000 times a second. Second is the IRQ. It has the low priority. It's triggered by Timer0 twenty times per second.
Is it normal, to enter Abort Mode? Maybe it has not been a good idea to place a printf inside the IRQ-routine. But i'hve done this only for debuggung purposes. I haven't got a compiler (CARM) warning.
Best regards
My second request is whether some native english speakers would please correct my grammar mistakes, just to teach me better english. In school, teachers allways give me an F. But i promise to do my best furthermore. :-)
The required stack size depends completely on what you do. It is hard to suggest a stack size without knowing how it will be used.
