Re: Overlay to remap Pi 3 UART

Those 54 GPIOs are the full complement of those provided by the BCM283x. TXD0 and RXD0 are on GPIOs 32 and 33 because ttyAMA0 is used to drive the Bluetooth modem on a Pi3. I can also tell from that output that you don't have "enable_uart=1" in config.txt, otherwise TXD1 and RXD1 (ttyS0) would be s...

Re: Overlay to remap Pi 3 UART
