Arduino for STM32

I can help you with the contents of the file $ ls /etc/udev/rules.d 45-maple.rules 49-stlinkv1.rules 49-stlinkv2-1.rules 49-stlinkv2.rules 60-openrgb.rules 70-snap.core.rules 70-snap.mc-installer.rules $ cat 49-stlinkv2-1.rules # stm32 nucleo boards, with onboard st/linkv2-1 # ie, STM32F0, STM32F4. ...

You are right, I installed stlink-tools to have the st-info command available.
I found this in my command history: "sudo apt install stlink-tools"

There are several tools on my disk named "st-flash" $ locate st-flash /home/hennep/Arduino/hardware/Arduino_STM32/tools/linux/stlink/st-flash /home/hennep/Arduino/hardware/Arduino_STM32/tools/linux64/stlink/st-flash /home/hennep/Arduino/hardware/Arduino_STM32/tools/macosx/stlink/st-flash /home/henne...

I had already installed that programmer but I could not make it work with the Arduino_STM32 software from Roger Clark. So I dug a little deeper in the scripts. When I try to upload from the Arduino IDE, I get a different location every time I compile Sketch uses 14212 bytes (10%) of program storage ...

The st-info program shows that it is a 128k F1 Medium-density device Is there a way to check whether the board has the right microcontroller or not? $ st-info --probe Found 1 stlink programmers serial: 503f6f065265565031111067 openocd: "\x50\x3f\x6f\x06\x52\x65\x56\x50\x31\x11\x10\x67" flash: 131072...

I'm trying to upload the blink sketch to a blue pill board with the ST-link-V2 programmer. I bought 5 new boards on eBay and these show the same error all five. photo_2020-09-30_18-55-09.jpg Sketch uses 14212 bytes (21%) of program storage space. Maximum is 65536 bytes. Global variables use 3128 byt...
