I'm trying to program STM8S003f3 development board using Arduino IDE v1.8.9. I am using ST-Link V2 Programmer. I have selected Board and Programmer correctly.

I opened Blink Example and compile it. It compiled successfully. But every time I try to Upload, the IDE gave error message and never uploads the sketch in STM8S003f3 board.

It give the following error message:

I tried to plug ST-LINK V2 Programmer to different USB ports but error remains same. ST-LINK V2 Drivers are installer correctly as shown in device manager:

Please help me to solve this issue. Thanks!

I found the solution...

First of all I have to remove Flash Protection of the STM8S003f3 board. I used ST Visual Programmer tool to remove the protection. (ST Visual Programmer Quick Tutorial: http://digital-wizard.net/stm8_tutorials/programming_stm8_using_swim)

How to Remove the Flash Protection:

  1. Connect the board with ST-LINK programmer and plug the programmer in USB.
  2. Open "ST Visual Programmer" application.
  3. Select relevant configuration setting according to your board and programmer.
  4. Go to OPTION BYTE tab.
  5. Set ROP to Off and then press CTRL+P

Now you can Open Arduino IDE and upload the code easily without that error.

Just for future reference in case others land here via google: There is an easier solution: Just click on Tools->Burn Bootloader. See #85 and https://tenbaht.github.io/sduino/hardware/stm8blue/#unlocking-a-write-protected-mcu
