Hi,

I can't see a way how to simulate/inject first two errors.

To trigger RWW error, you can start a flash operation (like program or erase) on certain block. At the same time, you can read data from the same partition. This will trigger machine check error and RWE in MCR register will be set.

Regards,

Lukas
