      Hello everyone,

      I am currently working with the VOXL2 Board. Following the instructions in the documentation (https://docs.modalai.com/voxl-developer-bootcamp/), I successfully started up the hardware and set up ADB. While setting up WiFi, I executed the command adb shell voxl-wifi, entered station mode, and provided the SSID and password for the WiFi connection. As instructed, I rebooted the hardware to complete the setup.

      Since then, I have been unable to detect the hardware on ADB. Although the three LEDs on the board turn green, no device is detected on ADB. Assuming the firmware might be corrupted, I followed the unbricking guide (https://docs.modalai.com/voxl2-unbricking/). Despite following all the steps, the device is still not detected on ADB. Running the lsusb command shows the device being detected as a Generic Modem Driver (QDL mode).

      I have also reattempted the unbricking steps, but they fail when trying to flash CDT.

      I am seeking assistance to resolve this issue and resume working with the board. Please let me know if any additional information is required.

      Looking forward to a quick resolution.

      Regards,
      Ashwin

          @ashwin Can you confirm that you're loading the correct QDL image for your board? M0054-1 vs M0054-2 (https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2)

            @tom I apologize for the delayed response.
            I did refer to this document and am using the correct QDLimage.
            I am using M0054-1 as the chip on the board says QRB5165M

              @ashwin What do you see if you run dmesg -wH and then power and plug in the board via USB

                  @ashwin Okay so it is enumerating into a bricked state as expected. If you switch SW2 to on and repeat the same test what do you see?

                    @tom The output is exactly the same irrespective of whether the SW2 is ON or OFF.

                      @ashwin Interesting, can you post the output of the failure you're seeing when you attempt to flash the board via. QDL?

                          Hello @tom ,

                          Just following up on this.
                          Is there any potential way to revive the board?

                          Regards,
                          Ashwin

                            Hey @ashwin, inside the following path:

                            modal-qdl/qdl/qfil_app/src/data/qfil/cdt

                            Can you run the following command and post the output?:

                            sudo /usr/local/bin/qdl \
  --debug --storage ufs \
  --include . \
  prog_firehose_ddr.elf \
  rawprogram3_RB5.xml \
  patch3.xml

                            This will give a more verbose output as to why your VOXL 2 is failing the CDT flash, thanks!
