RM57L843: Flash not all FF's after complete erase

Ravi Teja Darbha

Part Number: RM57L843

Tool/software:

Hi,

I am seeing an issue where after complete flash erase, I am seeing values that are not exactly 0xFFFFFFFF as shown in the image below. Can anyone explain to me the reason why it is not all FF's?

Thanks,

Ravi

Hi Ravi,

This is expected behavior only; this is caused by due to ECC single bit corrections and ECC correction and detection in this device will always be in enabled state only.
