Hello,

how is it possible to write '1' to the flash memory? Is it only possible after a complete erase of the full sector?

Or is it possible to do it with any trick?

I need to write a flag (for my Bootloader)and reset it in main application, i would prefer Bank1 Flash Sector1 (B1F1).

Thanks, Heribert

Hi,

To write '1' to the flash memory you must erase the needed sector.

Best regards,

Bouha.

Thanks to Bouha,

after erase the sector and rewrite it, all works.

Thanks also RISC for the link to ''STR7 Family Flash Programming Reference Manual'' and all other posted helps.
