      I am getting a "NACK Received" when I am trying to update the firmware on my voxl esc. I get to about 4% and then I get this error
      Here is a video explaining it in closer detail

        @wilkinsaf , you have a M0117 ESC, this can be seen @ 0:32 of your video (and other parts), but you are trying to install firmware for M0138 ESC.

        Also, three of your ESC channels have ESC version 39 (ids 0,1,2) and id 3 has firmware version 36.

        In any case, you can use the following script to auto detect the ESC (and pick correct firmware) and install it :

        cd /usr/share/modalai/voxl-esc-tools/
./voxl-esc-upload-firmware-all.sh

        This should update firmware for all all 4 ESCs.

        Then you will need to install the desired ESC params to your ESC. Please note that IDs 0 and 3 are missing params (that is why they are defaulting to 57600 baud rate), but the voxl-esc-upload-params.py script should take care of it. You can always force the update params script to use specific baud rate (such as 57600).

          Yes, whenever I try to have the auto-update for the firmware I get this

            When I try and update the parameters I get

              Ok, Here is how I solved it.

              1. Installed old firmware: ./voxl-esc-upload-firmware.py --firmware-baud-rate 57600 -f firmware/old/modalai_esc_firmware_m0117_1_v0_36_f75f1fdb.bin --id 0
              2. Installed newer firmware: ./voxl-esc-upload-firmware.py --firmware-baud-rate 250000 -f firmware/modalai_esc_firmware_m0117_1_v0_39_RC10_eb6fb500.bin --id 0

              I was loading a custom SDK on this vehicle so I am theorizing that there is somehting custom/funky going on with voxl-esc

                @wilkinsaf , yes, you got it. By the way, you did not have to restore the old firmware, you could have just done this:

                ./voxl-esc-upload-firmware.py --firmware-baud-rate 57600 -f firmware/modalai_esc_firmware_m0117_1_v0_39_RC10_eb6fb500.bin --id 0

                The following note does not really help, if you also have power connected to VOXL2..

                WARNING: Specified ESC ID not detected; perform manual power cycle now

                However, if the ESC is connected to a PC, you can just power cycle the ESC and the the bootloader will start up and firmware update will being.
