Hi,
I was uploading programs to Standard STM32F051R8 development board. While trying to upload the code, suddenly I have started getting an error message
"ST link No MCU Device found". After I click on OK I got another message "failed to load flash loader: C:\ProgramFiles\IAR-------Flashloader\ST\flashSTM32F05xx8.h". Then click on OK will generate another error "A fatal error has occurred, The debugger will terminate" . I have removed and reinstalled the driver for STlink. I have used a pin near to BOOT0. Accidentally, if a high or low to BOOT0 will make any issues??????
Also I am able to upload the program with one condition. Hold the reset key, then upload the program and then release the reset button. This will upload program. can anybody share any solution?????
