I am unable to write to flash of STM8S105C6T8 although I can read the flash. I am using stlinkV2 via SWIM and stm8flash programming tool under ubuntu. I tried to reset option bytes to factory default and use the -u (unlock) option of stm8flash but bo...

That's interesting to know; I had assumed that the RESET line needed to be asserted before the entry sequence is initiated but then it this were true, one would not be able to use SWIM as a debugger!!

If the MCU is not responding via UART, have you tried using SWIM? I do most of my programming using a STlinkv2 usb adapter and stm8flash under linux. There was an instance when I attempted to enable the bootloader by writing 55AA to OPTBL but contrar...

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 bootl...

You would need to configure the SPI in "simplex" mode. See 20.3.4 on page 268 in RM0016.

According to the datasheets this chip has a bootloader; is there any reason you want to write your own? In any event, I am sure you can write your own, and in fact someone wrote a very compact one (I have not used it yet as the STM8S105 I am using ha...
