Questions tagged [serial]
is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. Traditionally "serial" relates to a three (or more with hardware handshaking) wire system (TIA-232-F), now using ∓25V Voltages. Technically speaking the specialized SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) buses are serial communication systems as well - use one of those tags if they would be more appropriate!

U-Boot on alternative pins
My GPIO 14/15 pins (and I believe UART0 and UART1) are broken, so I cannot use the default serial port for U-Boot.
How can I get U-Boot to boot on a different serial port on my Raspberry Pi 4B?
