UART receive data
Note 1: By default, SER0_RX/TX carries the Debug console output of U-Boot and Linux, typically at 115200Bd/8N1. The same serial signals (level-
shifted to 3.3 V) also connect to the on-board Serial Debug connector, see also chapter 5.7. So for access to the serial Console of U-Boot / Linux,
either one connection can be used as appropriate.
4.12 I²C Bus
I2C_GP on the SMARC™ connector is also linked to an on-module EEPROM at address 0x50.
For further I²C bus signals see also Camera, LCD/LVDS and System Management interfaces.
