Copy firmware from one STM32F103C8T6 to another

[Resuna]

I soft-bricked a keyboard using a STM32F103C8T6 by, I think, trying to write too large an image, and I guess I overwrote the USB bootloader. I have an identical keyboard and I just ordered an ST-Link v2 but I haven’t been able to pull up instructions for cloning the firmware from the working board using the ST-Link. Is this possible?

Hello ​@Resuna and welcome to the ST community,

It’s possible unless the RDP (flash read protection) was not enabled in the device you need to read the flash content.

How would I actually do it? I think I would need to be using this utility, since I’m on a Mac:

• https://github.com/stlink-org/stlink

I do have access to a Windows laptop but it’s not the most convenient option.

Also, looking for the Windows software on st.com is a bit frustrating.

Install STM32CubeProgrammer tool downloadable from here: https://www.st.com/en/development-tools/stm32cubeprog.html

Please watch this video on Youtube: [Getting started] STM32CubeProgrammer

PS: avoid using cloned STLINK as you may face connection issues. Read this: How to recognize a genuine ST-LINK/V2 versus a cloned one

They really need to have a better search function, but thanks.

 

I had already ordered this from Adafruit industries based on the recommendation on a hobbyist board.

For your attention, that’s not a ST product.

The Adafruit part worked perfectly perfectly with that application.
