STM32CubeIDE also allows for debugging to track down any potential software issues that could be causing the bootloader failure.Conclusion:
Bootloader failures in the STM32L051C8T6 can stem from various factors like incorrect pin configuration, corrupted bootloader code, flash memory problems, voltage issues, or software conflicts. By following the above troubleshooting steps, you should be able to identify and resolve the issue, getting your microcontroller up and running again. Always ensure to check each aspect systematically to avoid overlooking any potential problem.
