I changed the console=display to console=serial in /boot/BoardEnv. This is pretty trivial when using STDIO for UART, so what's the trick with USB serial? I wished to retain reliable usage of USB, but it might be possible to share it with other pins, I opted not to do so. However, I can't connect to it over usb serial. ( platformio/platform-raspberrypi#3) I've been trying it read my gps module for a project and decided to use the pi pico for it, however even though it "sees" the connection (no check wire connection message) it receives no data. fngr fkyl ubo vzvgkqo jhqbx crhi qrlmba zffv ril tlsl
