Hi, All
My chip is STM32F405. Firmware for PYBv1.1 boards is downloaded into this chip. The version is V1.16. After power on, the UART6 does not work. There is no any data bit on Tx pin when software execute sending data, Help me , let it work normally. thanks.
UART6 issue
Re: UART6 issue
The REPL doesn't show up on the UART by default. It only shows on USB. If you want the REPL to show on a UART by default then you'll need to build your own custom firmware.
Is the crystal for your board the same frequency (the PYBV11 uses a 12 MHz crystal).
