Getting into the board
 | The Qualcomm Dragonwing Technical Guide documentation from RidgeRun is presently being developed. |
Conecting to board through UART Shell
To set up the debug UART connection and view the diagnostic messages, connect the debug-USB cable from the debug-USB port on the Qualcomm® Dragonwing™ IQ-9075 EVK device to the Linux host.
Install minicom on host:
sudo apt update sudo apt install minicom
Check the USB port:
ls /dev/ttyUSB*
Connect to board
sudo minicom -D /dev/ttyUSB1 -b 115200
Then sign in to the console with the following credentials:
login: root password: oelinux123
Connecting to network
The board has an Ethernet port that can be connected to router to have internet access. Wi-Fi is operational in Station mode. The Wi-Fi host driver and the authentication for network management are initialized during the device boot up. Connect to router:
nmcli dev wifi connect <WiFi-SSID> password <WiFi-password>
If something goes wrong, try deleting the connection with:
nmcli connection delete <WiFi-SSID>
 | lleon: use environment variables to set the SSID and password. In general, avoid placing <braces> (please remove this box when addressed) |
And retry. Check status:
nmcli -p device
Check WLAN connection status and IP address:
ip address show wlp1s0
Check connection by pinging a website:
ping google.com
Connecting through ssh
Establish the network connectivity before connecting to SSH. Locate the IP address of the device according to the type of network connection, using the UART console on the Linux host:
- For Ethernet:
ip address show eth2
- For WiFi:
ip address show wlp1s0
Then use the IP address from the Linux host to establish an SSH connection to the device:
ssh root@ip-address
