Hi,

How do you program the PFlash block?

You cannot execute any flash command from the same PFlash block you want to erase/program. The function should be place in RAM.

Also, check whether the PFlash area is protected or not. In case of a protection violation, FPVIOL flag is set in FSTAT register.

Please see the attached example code.

Regards,

Daniel
