Thank you very much! I followed your instructions precisely but unfortunately I cannot connect to the device. I used USB to TTL module with no luck.
Your help is much appreciated. Have a great day!
Thank you for the message, could you please send info in regards to flashing through the programmer directly. It is my only choice since the F1/Power combination does not work. Also the PC does not recognize the device. Thank You!
Hello. When flashing it is important to charge the batteries and use the laptop then there will be less problems. Try updating again by turning on boot mode by holding down the F1 key and pressing the power button. If it does not help, then just flashing through the programmer directly. I didn’t write in more detail because if not skillful actions can damage the device, it is used for programming STM ST-Link Utility
