Arduino for STM32

For quite some time I am getting error messages when I compile and upload a STM32 project with the Arduino IDE.


Sketch uses 14148 bytes (43%) of program storage space. Maximum is 32768 bytes.
Global variables use 2064 bytes (20%) of dynamic memory, leaving 8176 bytes for local variables. Maximum ...

Maybe I should have mentioned that the board is also a clone. :-)

I tried programming using the USB port a few times and noticed that it is not reliable. Since I am using a much shorter USB cable (about. 10", 25cm), performance has improved.

Using USB, I have to press the ...

I'm trying connect to a Nucleo STM32F072 board using the SWD interface.

I can program the board with the blink program but I need to disconnect the SWD cable after programming every time and connect a different cable (USB) to power the board to test the new program.
What I would like to know, is ...

You tried:
$ st-flash --reset write ~/Desktop/gpio.bin 0x8000000

Are you sure there is only one such script on your system?

To be sure that you use the right script from stlink-tools try:
$ /usr/bin/st-flash --reset write ~/Desktop/gpio.bin 0x8000000

I'm not an expert in this matter. It was ...

I can help you with the contents of the file
$ ls /etc/udev/rules.d

$ cat 49-stlinkv2-1.rules

# stm32 nucleo boards, with onboard st/linkv2-1
# ie, STM32F0 ...

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

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 ...

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?

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.
