The embedded SW, which run from Eclipse, receives the interrupt hardware failure exception error. This happens only in the "free running" mode of SW - I just give it run as is. This exception doesn't happen when running it in the step-by-step debug mode. The SW is running in the on-board ARM M4. It tries to write/read to/from Altera Aria-V. It seems the problem in the access rate of ARM to FPGA, but I'm not sure... Any ideas? Thank you!
