Hello,I am a Chinese,it is the first time I chatting in this Forum. I have problem with Maple(stm32f103RBt6),I build this by myself weeks ago.when I connect the USB transistor'B PIN I can download and use serial.If I don't connect it but I press the RESET button and the BUT button as the instrument say,the Maple couldn't connected with my PC(I can see the light blink as expect).How can I solve this problem.I have flashed maple_boot.bin in it.
Thanks!
