Can stm32 use LED flashing to indicate download progress during program download? [Copy link]

During the process of burning the program, the LED will flash, indicating that the program is being downloaded, and it will be always on when the download is complete. How can this be achieved?

If it does not meet your requirements, you can look at the cmsis-dap code and modify it to implement it on the emulator side or let the downloaded MCU run after downloading. The downloaded MCU code determines the first startup control LED is always on.
