Interrupt hardware failure exception

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!
