Interrupt hardware failure exception

Honored Contributor II

Hi All, 


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!
