PMU MBIST

Hi,

I am trying to figure out how to use the PMU MBIST. I want to verify my DRAMs, I read the documents and understood the following:

  1. The MBIST is part of the PMU ROM code. 
  2. Because the UBoot is loaded to the DRAM I need to initiate the test before the UBoot is loaded by the FSBL
  3. Starting the MBISTs tests is done using the PMU global registers

I added the code to start the MBIST and check the status in the FSBL code at the end of stage 2, but after this the FSBL failed to program the bitstream.

 - So where is the best place to put the code to start the MBIST : FSBL code? PMU FW code?

 

Thank you
