I flashed my file through st-link in cubeide and everything worked fine. Through the uart, it completes the firmware, but the LED does not blink. what could I have missed and what could be the problem?

You shouldn't flash the .elf file, but a raw binary. Use objcopy to create a .bin file from the .elf file.
