UPDATE! I tried several times to change RDP to BB and back to AA, and today after several tries I made it. But even with this, it is the same. I can not upload a sketch over the Arduino IDE, I can not upload HEX over the STM32CubeProgrammer, but I can by using MikroE tools. This is all new to me and...
