I have a question regarding MBIST execution, I can write to all bits in MEMTEST register to start MBIST for all instances, except for CPU0_DMEM1 and CPU1_DMEM1, a bus error is invoked, I figure it is something to do with DMEM1 itself but what could affect these exact instances that I cant write to the corresponding MEMTEST bits and the rest everything is fine.

Are you using the iLLD code, or rolling your own? In the iLLD, it's pretty easy:
If you're rolling your own, you have to be very careful to avoid accessing the memories being tested, because it'll cause a bus error.
IfxMtu_runMbistAll( mbistGangConfig );
If you're rolling your own, you have to be very careful to avoid accessing the memories being tested, because it'll cause a bus error.
