Hello, I have some CM4 boards and am interested in I2C, UART and ETH BUS. However, I looked at the CM4 datasheet at the link to complete the I2c connection and noticed that Table 1. GPIO pins alternative function assignment and Table 6: Pinout have different interpretations. So in the end, which information is the correct information? I need a specific, clear, detailed conclusion to be able to connect the hardware correctly.
