[FEsfa.1]

Using STLINK-V3SET. Please Note in circuit STM8S105K6T6C  embedded board has these pins GND, RX, TX , VCC. Many thanks

I'd guess you'd just use the VCP COM port with Flasher STM8..

Thank you. I am new to this field would you please elaborate more?

There also are alternatives to the Windows-only FLASHER-STM8, e.g.:

I have been programming the STM8S105C6 chip using a STLinkV2 programming cable and the SWIM interface (you need to connect to SWIM, RESET, GND) and stm8flash. In recent days I have been experimenting with programming using UART and the built-in bootloader with limited success.
