      @Kashish-Garg-0 , I understand.

      Can you try this procedure to force into fastboot and then perform SDK install?

        @Alex-Kushleyev Hey Alex, we have gone through this procedure a few times, even had a partner to make sure the button was being pressed appropriately. When running fastboot devices, no device gets identified.

          @Kashish-Garg-0 , I understand, thanks for clarifying.

          My colleague, who has more experience with this, was out of office last week, coming back tomorrow. I will make sure he takes a look at your post, he may have some suggestions. @tom

          Alex

            @Kashish-Garg-0 With your device plugged in to your host pc via usb, what do you see with lsusb on your host PC?

                @Kashish-Garg-0 Okay so the device is booting into EDL mode, which is what is used for QDL flashing. Can you confirm that the EDL switch is turned off?

                  @tom Yes the EDL Switch is turned OFF, pointing away from the Processor

                    @Kashish-Garg-0 And when you went through the QDL process did the QDL flashing complete as expected? Should take around 10 minutes to complete

                      @tom I just re ran it and it took around 7 minutes or so and gave the appropriate output:

                        @Kashish-Garg-0 And then if you remove and replace both power and usb is it still booting to that same mode?

                          @tom You mean is it going to EDL mode after replacing power/usb and moving the EDL Switch to off?

                          Is what is being printed with lsusb now

                            @Kashish-Garg-0 Sounds like we'll have get an RMA going for this one: https://www.modalai.com/pages/rma

                              @Kashish-Garg-0 It's possible your board has a QSM8250 (M0054-2) instead of a QRB5165 (M0054-1), see here for the diffs: https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

                              If that is the case then you will have to QDL using a different build, which you can download from downloads.modalai.com, look for M0054-2 Starling QDL Image 1.7.4 2024-02-09-1.7.4-M0054-2.zip under the "All" category
