Note

When using the ST-Link V2 to program the STM32F103C8T6, follow these steps to ensure proper setup:

1.Set BOOT1 to 0 and BOOT0 to 1 to enter programming mode.

2.Press the reset button to initiate the programming state.

3.Set BOOT0 back to 0 to enter running mode.

4.Press the reset button again to start executing your program.

For seamless integration with PlatformIO, make necessary adjustments to the stm32f1x.cfg file and platformio.ini to accommodate the chip's ID.

Download the program and debug it using Platform IO, the chip's ID has a little different and requires some adjustments in PlatformIO (Change a line in the stm32f1x.cfg file to set _CPUTAPID 0x2ba01477 and added upload_flags - =c setting CPITAPID 0x2ba01477 to plaformio.ini), programming a simple blink test in release mode worked using the ST Link clone, as did a debug build with a breakpoint.
