I develop a custom board based at STM32 F103VCT6. Following project requirements I cannot use CubeMX-generated HAL, so my decision was to use stm32duino. Obviously I've started from a new variant for this board, please see it in attached.
I've double checked pins and overall structure of "/wirish/*" initializers. When I came to uploading, seems nothing is working, meaning, looks like the mcu is stuck initializing, even the led on PA15 won't blinking.
I am a newbie in stm32s', so this is my first project. I appreciate a hint what is going wrong here.
