Hi ST community, I would like to use CH340G USB UART converter for programming STM32F446RE Microcontroller. How can I do this? Any advice or idea about this? Thx a lot. :)

Normally I use ST-link for programming. But I can not see data in serial port on computer. I use TMS,TCK,RST pins for programming. I would like to solve this issue for my new design. Could help me please? What I need to learn exactly ?
