ChibiOS Free Embedded RTOS

I tried the main() that I posted before, there is one FPU instruction in the fast handler, it worked.

Two or three version ago we found a bug regarding fast interrupts and FPU but it has been fixed, see the changelog. There is still all the discussion in the forum.

I will update the "FPU_STORM" test application with the fast IRQ and run it again, just in case.

The

seems to be working. Both of my boards are blinking LED's for almost an hour. I'll try to test it for a more long time, and I hope, problem will not appear again. Thank you!

It is most likely a stack overflow: keil+no optimizations+FPU = lot of stack used.
