Part Number: TMS320F2800137

Tool/software:

1. If I config all LS ram to Z1 and unsecured Z1 by executing PMF. Then I config RAMOPENFRC, will LS0_1 will be initialized？Will RAMOPENSTAT turn to 0x1 eventually?

2. If I config all LS ram to Z1 and Z1 is secured. Will LS0_1 will be initialized if I config RAMOPENCLR when RANOPEN feature is not enabled by set RAMOPENFRC?

Hi Liu Liu,

1. I believe the RAM will be wiped to 0 in this case.

2. If RAMOPENCLR is set, this will also cause the RAM to be wiped to 0.

It's possible that "wiping" the RAM actually sets it all to 1s, could you test this to check?

Thank you,

Luke

2. I mean will the ram be wiped to 0 if I set RAMOPENCLR when RAMOPENSTAT is 0?

Hi Liu Liu,

Based on the register description, it doesn't matter whether the RAMOPENSTAT bit is a 0 or a 1. I expect the RAM will be wiped no matter what:

Thank you,
