TMS570LC4357: Enabling ECC in VIM RAM resulting in ESM Errors

TMS570LC4357: DMAPAR - Register not Updated with Error Adresse after 2-Bit fault injection

Hi experts,

While testing our implementation of the DMA 2bit ECC Test, we noticed that in the DMAPAR-Register the Error-Flag did get set, but not the ERRORADDRESS.

(Q1) Is this a bug in the HW or what could be the Problem?

Thank you and best regards,
Max
