6.10.1 UART

The UART loopback test is for reference only.

❶ copy com to SD card and then insert it to the card slot.

❷ power on. After the system boot, execute the command to copy com from SD card to the board.

1copy /media/linaro/New/com /system  //com absolute path: /media/linaro/New/
2chmod 777 /system/com               //modify com file properties

❸ connect the transmit (TX) pin to the receive (RX) pin of UART. After executes the command, input character to test UART.

UART
