Description

I have an STM32F103RCT6 board. While testing it in the above mode, it suddenly stopped functioning. When I attempted to power it on again, it emitted a buzzing sound and immediately shut down. Additionally, the MCU detection by STLink failed. I have consulted the wiki for troubleshooting tips, but none seem to be effective. Any idea what might have gone wrong?

Have you tried keeping the power button pressed while connecting with STLink? Could it be shutting down because it isn't configured correctly and thinks the battery is dead?

I tried the above solution , still no detection of mcu by stlink . Another observation is , there is different sound produce not the buzz, and the mcu gets heats up .

If you do a continuity check between vcc and gnd, it's probably shorted now.
