flash word write and byte write

Question asked by gman on Sep 1, 2011

I am using the STM32F series. Right now I am writing to the flash one word at time. I have no problem doing this. I now implemented a function that writes one byte at a time. When I try to do this, I get the "programming parallelism error" (PGPERR bit in FLASH_SR register). However, I have correctly changed the PSIZE bits in the control register and this has been verified in the debug window. Does anybody know why I am getting this error?

Clive1 I know you're out there. You helped me solve my last problem.

Any input is much appreciated.
