After you have flashed Qualcomm Linux, use this page to bring the device up: connect the debug serial console, verify the software version, get on the network, and connect over SSH and display.
If you have not flashed the device yet, start with Update software.

​
Set up the debug UART

The debug UART gives you a serial console into the device — your primary way to log in and check the device after flashing.
  1. Connect one end of a micro-USB cable to the micro-USB port on the IQ-9075 EVK.
  2. Connect the other end to your host computer.
Micro-USB port location
  1. Open the serial console for your host OS:
Install screen:
sudo apt update
sudo apt install screen
List the serial devices:
ls /dev/ttyUSB*
Sample output:
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2  /dev/ttyUSB3
The IQ-9075 EVK’s onboard adapter exposes four serial devices; the main console is the second one (/dev/ttyUSB1). Open it at 115200 baud:
sudo screen /dev/ttyUSB1 115200
  1. Press Enter to bring up the login prompt, then sign in:
    • Username: root
    • Password: oelinux123

​
Verify the software version

Confirm the device is running Qualcomm Linux: 
cat /etc/os-release
Expected output: 
ID=qcom-distro-sota
NAME="Qualcomm Linux Reference Distro(OTA-enabled)"
VERSION="2.0"
PRETTY_NAME="Qualcomm Linux Reference Distro (OTA-enabled) 2.0"
Check the kernel version: 
uname -a
Expected output: 
Linux iq-9075-evk 6.18.30-... #1 SMP PREEMPT ... aarch64 GNU/Linux
If the version doesn’t match, or you can’t reach a login prompt at all, the image is missing or outdated. Go back to Update software and flash the latest Qualcomm Linux.

​
Connect to the network

Bring the device online over Wi-Fi or Ethernet so you can use SSH and download artifacts.

​
Wi-Fi

The device runs Wi-Fi in station mode. Connect with nmcli: 
nmcli dev wifi connect <WiFi-SSID> password <WiFi-password>
Example — network QualcommWiFi, password 1234567890: 
nmcli dev wifi connect QualcommWiFi password 1234567890
Sample output: 
Device 'wlp1s0' successfully activated with 'd7b990bd-3b77-4b13-b239-b706553abaf8'.
Verify the connection and get the IP address: 
nmcli -p device
ip addr show wlp1s0
Confirm internet access: 
ping qualcomm.com

​
Ethernet

Connect an Ethernet cable from the RJ45 port on the EVK to your network router, then read the IP address: 
ip addr show end0
The value of inet in the output is the device’s IP address.

​
Connect over SSH

SSH gives you a network terminal into the device from your host computer.
Ensure your host computer is on the same network as the device.
  1. Find the device IP address (from the network step above):
    • Ethernet: ip addr show end0
    • Wi-Fi: ip addr show wlp1s0
  2. Connect from the host: 
    ssh root@<ip-address>
    Example: 
    ssh root@192.168.0.222
  3. Enter the password oelinux123 when prompted.

​
Connect a display

Connect a monitor to DisplayPort0 (JEDP0) or JEDP1 on the EVK using an active Mini DisplayPort-to-DisplayPort cable (included in the box), or an active Mini DisplayPort-to-HDMI adapter (not included).
Display output works only through the DisplayPort connectors. There is no display output through the USB Type-C ports.
Mini-DisplayPort to DisplayPort cable Power on the device and verify the display shows the expected startup output.

​
SBC (Single Board Computer) mode

To use the EVK as a standalone computer with a keyboard, mouse, and monitor: SBC example connection
  • Power: connect the 12 V adapter.
  • Serial console: micro-USB to your host for UART logs (optional once set up).
  • USB hub: connect a powered USB hub to a USB Type-C port for multiple peripherals.
  • Keyboard & mouse: plug into the USB hub.
  • USB camera: connect to the USB hub (must be UVC-compliant).
  • MIPI camera: attach to a MIPI CSI connector on the board.
  • Display: Mini DisplayPort to DisplayPort cable, or an active Mini DisplayPort-to-HDMI adapter.
