MPC5643l External Reset

I'm trying to reset the micro via external reset, i.e. moving to low the RESET_B pin.

In the RM the external reset is classified as non destructive reset (in the same way as SW functional reset) so I expected that the RAM content will be preserved after external reset.

Instead I observed that the SRAM is no more initialized after an external reset and needs a complete initialization to avoid ECC errors.

I'm using a MPC5643l cut 3.1.

What is the expected behavior after external reset regarding data in RAM?


Thank you in advance

Best Regards,
