ls /dev            //View SSD device name
mke2fs -t ext4 /dev/nvme0n1           // If SSD is not ext4 format, format it to ext4
mkdir /mnt/ssd                        // Create a new directory
mount -t ext4 /dev/nvme0n1 /mnt/ssd   // Mount SSD to the new directory
ls /mnt/ssd                           // View the contents of the ssd

6.7 WiFi

Connect the WiFi antenna, then click the network icon in the lower right corner of the UI interface, select the SSID from the list of available networks and enter the password. After connected, can ping the URL/IP at the terminal.

ifconfig

ping www.boardcon.com

6.8 Bluetooth

bt_load_rtk_firmware   //turn on bluetooth

click the Bluetooth icon in the lower right corner of the desktop and select the Devices… option.

click the Search button to start searching and select the available device in the list to pair. After pairing, devices can connect with each other automatically.

6.9 Ethernet

Connect the board and router with an Ethernet cable (default DHCP=Yes). User can ping URL/IP at terminal. or open the browser to test Network.

ifconfig

ping www.boardcon.com

6.10 RTC

Execute the follow command to set the RTC time.

hwclock -w

After the board is turned off, the RTC supports battery power supply, and RTC clock to be saved.

6.11 UART

The UART loopback test is for reference only.

copy com to SD card and then insert it to the card slot. Powered on, after the system boot, execute the command to copy com from SD card to the board.

copy /media/linaro/New/com /system  //com absolute path: /media/linaro/New/
chmod 777 /system/com               //Modify com file properties

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

./system/com /dev/ttyS3 115200 8 0 1  //Test UART3

Press Ctrl+C to exit UART3 testing, execute the command to test UART4.

./system/com /dev/ttyS4 115200 8 0 1   //Test UART4

The method for testing UART5(ttyS5) and UART9(ttyS9) is similar.
