TMS320F280025: enter illegal interrupt

Part Number: TMS320F280025

Hi Expert,

My customer meet an issue which will go into the illegal interrupt after erasing flash.

In detail, call  the Fapi function: Fapi_setActiveFlashBank(), the DSP will trigger an abnormal handle --Interrupt_illegalOperationHandler

 

And they can solve the issue by decreasing the opt speed level.

The CCS compiler version is: 10.0.0.00010, and the optimization level is 3.(This level has issue)

 

I have customer try disabling ECC-check before calling API functions as this post talked about. But no improvement.

Could you kindly help to give other suggestions?
