Debugging STM8AF series processor

[Lipson]

I got an ECU from an manufacturer, I was very interested in extracting the firmware from the ECU .They have used STM8AF controller , Open-OCD doesn't have support for the controller. Please reply I you guys have any idea about debugging the controller using opensource software like Open-OCD !!!!!!!

Welcome @Lipson, to the community!

The MCUs of ECUs, including the STM8AF, are typically protected by the respective ECU manufacturer with read-out protection to prevent unauthorised access to the manufacturer's IP. So I give you exactly zero hope that you can read out or change the firmware.

Hope that answers your question?
