Hi all,

Why many Pflash ECC errors are reported on high temperature test while room temperature/low temperature tests are ok?

Best regards,
Lucas

Hi Lucas,

Check flash waitstate if it is enough to cover the access delay by PMU_FCON.WSPFLASH. The default setting is calculated with lower fFSI. with higher fFSI, you need to configure more waitstates.

Hello Support,
What is the corresponding register for Aurix 2G devices?
Looks like PMU_FCON.WSPFLASH is for Aurix 1G devices.
Best Regards

For TC3xx, check DMU_HF_PWAIT and DMU_HF_DWAIT.
