Qualcomm Dragonwing EVK Setup Environment

This guide intends to cover how to download and flash software images of Ubuntu 24.04 LTS for the Qualcomm Dragonwing IQ-9075 EVK ^[1].

Prerequisites needed before starting:

1. Host computer with either an Ubuntu or Windows OS (This steps were verified with Ubuntu 24.04)

2. Development kit Dragonwing IQ-9075 EVK

3. A USB Type-C to USB Type-A cable to flash images to the Dragonwing IQ-9075 EVK

4. A micro USB to USB Type-A cable for the UART debug port

Setting up board communication

To setup the UART flashing log, follow these steps:

Warning

Don't log in to the console at this stage. Log-in will be performed up to the Getting into the Board section.

1. Connect the Micro-USB cable between the Micro-USB port on the Dragonwing IQ-9075 EVK and the USB-A port using the converter included in the DEVKIT.

2. Connect the USB-C cable between the ADB USB-C port and a USB-A port in your host computer using the USB-C/USB-A converter included in the DEVKIT.

3. Make sure the screen or the minicom application in your host computer. e.g.:

sudo apt update
sudo apt install minicom

4. Verify the USB port in which the UART communication is setted:

ls /dev/ttyUSB*

You should see something similar to:

/dev/ttyUSB1

5. Open the debug UART session:

sudo minicom -D /dev/ttyUSB1 -b 115200

Use wherever USB port was assigned to the Micro-USB.

Downloading Sources

Follow the next steps to download the firmware, device tree binary and image for Ubuntu 24.04 for the Qualcomm Dragonwing IQ-9075:

1. Create a directory to store the flashable images into your working directory $WORK_DIR:

Info

Adjust the directory path as needed.

export WORK_DIR=~/<path-to-work-dir>
cd $WORK_DIR
mkdir dw-ubuntu-images
cd dw-ubuntu-images

2. Download the boot firmware ^[2] and decompress the compressed file.

mv ~/Downloads/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins.tar.gz .
tar -xzf QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins.tar.gz

3. Download the device tree binary ^[3] and the rawprogram0.xml file ^[3] and move them to the binaries directory.

mv ~/Downloads/dtb.bin ~/Downloads/rawpgrogram0.xml ./QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/

Warning

The rawprogram0.xml may not download automatically. If this happens, create a file with that same name and copy those contents with your favorite text editor.

4. Download the compressed image file ^[3], extract it, and move the raw image to the dw-ubuntu-images/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins directory.

Info

Verify the Date and Version variables match with the latest image available from the canonical repository.

export DATE=20260306
export VERSION=4096b
export IMAGE=iot-qualcomm-dragonwing-classic-server-2404-x09-${DATE}.${VERSION}.img

wget "https://people.canonical.com/~platform/images/qualcomm-iot/ubuntu-24.04/ubuntu-24.04-x09/ubuntu-server-24.04/${IMAGE}.xz"

unxz ${IMAGE}.xz

mv ${IMAGE} ./QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/

5. Verify contents in the $WORK_DIR/dw-ubuntu-images/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/ directory:

ls QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins
