RL-ARM: CORTEX M3 HANGS WITH A HARD FAULT

QUESTION

I have a program running on a Cortex M3 device. After running for a random amount of time, it stops responding. If I debug the program, I see that the processor has jumped to the "Hard Fault" handler.

My program uses the RTX kernel.

ANSWER

This is corrected in RL-ARM V3.20.
