Is there a solution to erase one byte in the flash in order to reprogram it with a new value? I try to use it as an eeprom and i don't want to erase all the block to reprogram it

Thanks,

Sebastien

You can't erase a byte in the flash, because a block can be erase in the flash.

There is a idea to erase a byte:

1. you copy the block to RAM

2. erase the block

3. change the byte which you want to erase.

4. write them to the block.

Yes, you can update one byte at a time using the attached EEPROM emulation code.
