TMS320F280039: Hwbist's hwbist section address overlaps Pbist state address

mingcai jiang

Hi Team

Due to address conflict, the value read out is not 0x00, causing FuSaInfo.bit.b8MPOSTFlt = True; However, it should be FuSaInfo.bit.b8MPOSTFlt = false;

Helli,

Please take a look at this post: TMS320F280033: Hwbist's hwbist section address overlaps Pbist state address

While these overlap, MPOST will only execute on XRSn/Power up based resets. MPOST will not execute on HWBIST initiated resets.

Customer code can use the reset cause (RESC register in system control space) to determine if MPOST info or HWBIST info is stored in this memory region.

I hope to execute the MemorySafety_PowerOnSelfTest function, set FuSaInfo.bit.b8MPOSTFlt to false, and also be able to execute the STA_HWBIST_RunTest function. How can this be achieved? Could you draw a diagram or provide an example?
