Qualcomm Download (QDL) Tool
One-time Prerequisite
To set the udev USB rule with the Qualcomm manufacturing vendor ID 05c6:
$ cd /etc/udev/rules.d
$ sudo vi 51-qcom-usb.rules
# add the following
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9008", MODE="0666", GROUP="plugdev"
$ sudo systemctl restart udev
Use the QDL to flash images (UFS only now)
1. Ensure the QDL mode
$ lsusb Bus 001 Device 028: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)
2. Ensure ModemManager is not running It is identified as a Qualcomm modem for some Linux distributions when the device is connected in USB mode. Check the status of ModemManager:
$ sudo systemctl status ModemManager
If the ModemManager is enabling, please help to stop it by:
$ sudo systemctl stop ModemManager
3. Go to the location of images in the workspace to flash the images:
$ cd build-qcom-robotics-ros2-humble/tmp-glibc/deploy/images/qcm6490/qcom-robotics-full-image $ ./qdl prog_firehose_ddr.elf rawprogram*.xml patch*.xml HELLO version: 0x2 compatible: 0x1 max_len: 1024 mode: 0 READ64 image: 13 offset: 0x0 length: 0x40 READ64 image: 13 offset: 0x40 length: 0x3f0 READ64 image: 13 offset: 0x1000 length: 0x1000 READ64 image: 13 offset: 0x2000 length: 0x260 READ64 image: 13 offset: 0x3000 length: 0x1000 READ64 image: 13 offset: 0x4000 length: 0x1000 . . . Update Primary Header with CRC of Primary Header. LOG: INFO: Calling handler for patch Zero Out Header CRC in Backup Header. LOG: INFO: Calling handler for patch Update Backup Header with CRC of Backup Header. LOG: INFO: Calling handler for patch LOG: INFO: Calling handler for setbootablestoragedrive LOG: INFO: Using scheme of value= 1 partition 1 is now bootable LOG: INFO: Calling handler for power LOG: INFO: Will issue reset/power off 100 useconds, if this hangs check if watchdog is enabled LOG: INFO: bsp_target_reset() 1
If you see the "partition 1 is now bootable" in your terminal window, the flash is successful.
Note: If you get the following issue, please help to download the qdl file (https://www.dropbox.com/scl/fi/nv65h778rwkhtul1gnwrr/qdl?rlkey=gzy83yt1x2qhhnqzra9kukhai&st=p4n42eax&dl=0) or to build the standalone QDL.
$ ./qdl prog_firehose_ddr.elf rawprogram*.xml patch*.xml -bash: ./qdl: No such file or directory
How to build the standalone QDL?
$ sudo apt-get install libxml2-dev libudev-dev $ git clone https://git.codelinaro.org/linaro/qcomlt/qdl.git $ cd qdl $ make
