I needed a Blue Pill for a project. Got a few on ebay, but I couldn't find genuine STM32 ones in Europe. So I got ones with the compatible CKS32F103C8T6 chip.
I have never programmed a Blue Pill of any kind, so I don't really know how it is supposed to work. Programming with ST's UART tool didn't work for me, it didn't like the identity of the board. I instead got success using stm32flash, which can be found here https://sourceforge.net/projects/stm32flash/ .
I used some generic USB-to-UART cable, which identifies as being "Prolific USB-to-Serial". Make sure that the UART dongle works by doing a loop test.
To program the chip on the Blue Pill, follow these steps:
- On Blue Pill set jumper for"boot 0" to 1.
- Connect UART GND (black) to G on Blue Pill
UART 5V (red) to 5V on Blue Pill
UART RX (white) to A9 on Blue Pill
UART TX (green) to A10 on Blue Pill - From command line, run:
stm32flash -g 0x8000000 -b 115200 -w gd32f1_generic_boot20_pc13.bin COM4
where COM4 is whatever com-port the UART has attached to, and the bin-file is whatever bin-file you want to upload.
There seems to be some problem with paths and stm32flash, so I run everything from the same folder. - On Blue Pill set jumper for"boot 0" to 0.
- Push reset button on Blue Pill.
- Done!
