TMS570LC4357: DMA2: Non-Privileged Bus Master Access - How to implement?

Part Number: TMS570LC4357


Hi experts,

We are not entirely sure how the diagnostic "DMA2: Non-Privileged Bus Master Access" mentioned in the Safety Manual should be implemented, since no example is given.
If I understand the description correctly, we should initiate a write on a privileged mode register by configuring the DMA accordingly and then trigger the DMA to write to that register.
When DMA has finnished the transaction we can check the register and the write should have failed.

Is this correct?

Thank you and best regards,
Max
