Fast FLASH programming - mass erase neccesary?

Tobe · ‎2023-12-13

I read in the doc for the G431:

"The Flash main memory programming sequence in standard mode is as follows:
1. Perform a mass erase. If not, PGSERR is set."

So i can not do a single page erase??

Hello @Tobe ,

Yes, the fast programming mode can be performed just after a mass erase, if not, PGSERR (Programming Sequence Error bit) is set.

PGSERR bit: Programming Sequence Error is set in fast programming mode when the mass erase is not performed before setting FSTPG bit (Fast programming bit).

For more information please refer to Programming errors.

Thank you.
