TMS320F28388D: CM hard fault (faultISR()) during executing CiA402_Init() in ESS code.

Part Number: TMS320F28388D

Hi Champs,

My customer is evaluating F2838x CM core for EtherCAT CiA402 Driver Profile. Slave stack code generated from SSC Tool was merged to f2838x_cm_echoback_solution example.

There was no compiler error. But, fault interrupt (faultISR) occurred during executing CiA402_Init() function. I also duplicated this fault in my side.

Could you review what can trig this fault interrupt?

Thanks,

Steve
