    Hello,

    What is the state of the nTRST signal when you power up the board? The TMS570LS3137 rev A silicon has some known issues where you do require to assert power-on reset in order for the code to execute correctly.

    Did you mean that you have the 144QFP package for the 3137? If so, then the core power domain with the RTP could be disabled. Any access to RTP in this case would cause a data abort.

    Regards, Sunil
