Qualcomm Dragonwing EVK Flashing Image

Setting up the board in EDL Mode

1. Turn on the S2-3 DIP switch by pushing it up



Dragonwing S2-3 DIP switch.

2. Connect the board to a 12 V power supply
3. Connect the board to the host computer through a USB Type-C connector
4. Verify if the board enter EDL mode successfully with the lsusb command. You should see a similar output to the following:

   Bus 002 Device 014: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Update the UDEV rules.

1. Got to the udev configuration directory:

   cd /etc/udev/rules.d

2. Verify the contents in the directory:
   • If the 51-qcom-usb.rules does not exist, create it:

     sudo vi 51-qcom-usb.rules

   • Add thhe following contents:

     SUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9008", MODE="0664", GROUP="plugdev"

   • If it does exist, check the content to see if it matches with the previous line:

     cat 51-qcom-usb.rules

3. Restart the udev service:

   sudo systemctl restart udev

Install QDL Tools

1. Use the QDL tool to flash images into the board:
   1. Download the QDL tool and unzip the contents.

       mv ~/Downloads/QDL_2.7_Linux_x64.zip .
      unzip QDL_2.7_Linux_x64.zip

   2. Give executable permission:

      chmod +x $WORK_DIR/dw-ubuntu-images/QDL_2.5_Linux_x64

      Info

      Use the version name you just downloaded, this may change between versions. Within the unzipped directory, refer to the QDL_USER_GUIDE for more information on its usage.
2. Set the $qdl_tool_path variable:

    export qdl_tool_path=$WORK_DIR/dw-ubuntu-images/QDL_2.5_Linux_x64/

Flash binaries

1. Perform UFS provisioning on the board:
   1. Download the provision folder by running:

      wget https://artifacts.codelinaro.org/artifactory/codelinaro-le/Qualcomm_Linux/QCS9100/provision.zip
      unzip provision.zip

   2. Move the provision_1_2.xml file from the unzipped directory to the $WORK_DIR/dw-ubuntu-images/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/ directory:

      mv provision_1_2.xml ./QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/

   3. Provision UFS by running the following command from the unzipped provision directory:

      cd QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/
      $qdl_tool_path/qdl --storage ufs prog_firehose_ddr.elf provision_1_2.xml

2. Perform CDT Flashing:
   1. Download the CDT binary by running:

      wget https://artifacts.codelinaro.org/artifactory/codelinaro-le/Qualcomm_Linux/QCS9100/cdt/rb8_core_kit.zip
      unzip rb8_core_kit.zip

   2. Flash the CDT by running the following command from the unzipped CDT directory:

      $qdl_tool_path/qdl prog_firehose_ddr.elf rawprogram3.xml patch3.xml

3. Flash the Ubuntu software images:
   1. Go to $WORK_DIR/dw-ubuntu-images/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/sail_nor and flash RTSS:

      $qdl_tool_path/qdl --storage spinor prog_firehose_ddr.elf rawprogram0.xml patch0.xml

   2. Go to $WORK_DIR/dw-ubuntu-images/QLI.1.7-Ver.1.1-ubuntu-QCS9100-nhlos-bins/ and flash Ubuntu:

      $qdl_tool_path/qdl --storage ufs prog_firehose_ddr.elf rawprogram*.xml patch*.xml

Remember to take the device out of EDL mode and restart it.

It is recommended to connect the flashing USB-C cable directly to the host computer. Hubs and adapters might lead to issues when flashing.
