Firmware for STM32F103C8T6 built from SW4STM32 does not work Posted by dlsdking on 2018-05-21 09:34 Hi dh8607, can you confirm whether you are using STM32F103c8t6 or STM32F103cBt6? coz both of them are different and the firmware for one board might not work for other. Thanks and regards, Likith Sai
