How to read uninitialized ECC RAM in MPC5606

I would like to read areas in the RAM memory of an MPC5606 after power-up, before it gets initialized for correct ECC functioning.

I have read the speciffication for the ECC SRAM module but still it is not clear to me if what I am trying to do is possible at all.


A quick test with a simple project generated with the CodeWarrior for MCU wizzard shows that the entire RAM is initialized after startup, after the default startup code was executed.

I did not check yet how it looks before this.


If someone has experience with something like this I would appreaciate any hint on if and how can this be achieved.


Thanks in advance!
