Hi,

I use the Flasher STM8 in Standalone mode and I can't find a way to only erase certain sectors of a STM8S003F3 chip.
I want to re-program the chip program memory (0x8000 to 0x9FFF) while keeping EEPROM Data (0x4000 to 0x407F).

In Project Settings, under Flash, I set the Start Address to 0x8000 and End Address to 0x9FFF in order to only work on the Flash Program Memory.
In Auto mode, only the option "Erase Chip" is available and, obviously, it erases all sectors.

When unticking "Erase Chip" step in Auto and using command #ERASE instead, it still erases all sectors.
In the Flasher STM8 User Manual UM05006, it is said that using the #ERASE command should erase only selected sectors.

Is there another way or am I doing something wrong?

Best regards,
Halex

Hi,

The solution was simple.

Unticking "Erase Chip" in Auto will make the programmer operate only on selected sectors, no need to use the #ERASE command.
