equarles2, I'm facing very similar problem. Also using page 251
- receive data, and store at a temporary buffer
- at loop(), process the buffer: includes reading from flash, and very occasionally, writing to it
- a also have a timer (TIMER 2) to blink a led, and control a relay
The application is crashing at flash erase function. But now is the weird part of it, the application worked for some days, and then this problem appeared.
Did you find out anything since then?
