CCS/RM48L952: Disabling auto generation of ECC bits

Tool/software: Code Composer Studio

I am trying to gain a better understanding of how ECC bits work, and one test I am wanting to do is flash something with ECC checking enabled but ECC bits not set. It seems both CCS 7.2 and Uniflash 4.2 program ECC bits even when the "Auto ECC Generation" checkbox is not checked. I am validating this by looking at 0xF0400000. Is this a bug?

Hello,
I believe you are experiencing known issue: CCBT-1833 "Disabling "Auto ECC generation" Flash Option does not have any effect"

The bug is fairly old but still remains open. I am trying to get an update on status. I will keep you posted.

Thanks

Hello,
Sorry for the delayed response. The bug is still unresolved. It has been reassigned to the Hercules team and assigned a new ID: HERCULES_SW-6010

I don't have a timetable for resolution as it now owned by the device team. Sorry for the inconvenience.
