No firmware for STM32G0B0RET6 ?

[sudo-su-root]

Bought BIGTREETECH SKR Mini E3 V3.0 from BIGTREETECH store on Amazon UK

Connected board and Marlin was showing fine and I could probe the MCU from the pi via USB. Downloaded the correct prebuilt firmware from github and I could tell it flashed to some degree as screen was now all blue no longer showing Marlin. From this point onwards I cannot probe MCU via USB.

The description on amazon states STM32G0B1RET6 but on inspection it's been shipped with a STM32G0B0RET6.

Flashed the Marlin firmware from github even though it's probably for the wrong MCU and the screen comes back to life with Marlin but still cannot probe MCU via USB.

I have watched a good 10 videos covering the creation of firmware, followed the standard settings for STM32G0B1RET6 but changed just the MCU to STM32G0B0RET6 and it still does not fix the issues.

I suspect at this point the usb port is faulty but it would be nice if someone were to compile and upload a tested firmware.bin for this MCU. Maybe there is no real difference and the compiled firmware should be working fine. despite wrong MCU selection.

sudo dmesg -w output.....

edit, update...

Second board arrived from amazon, G0B1 instead of the G0B0 and everything is working as expected so it was either a duff USB port or the firmware that killed it.

Hello, I think the image you shared is klipper. I am looking for marlin source code.
