  Hey @Alex-Kushleyev how can I get on that mailing list for the ModalAI sanctioned mast? I designed and 3DP two mounts and used a carbon fibre rod, along with a copper laminate board and seen great improvement in GPS count (see image and screenshot).
  Did a couple test flights with this set up and everything ran smoothly. I'll have a better peace of mind with an official mast though.

  Looking forward to your response!

  Hi everyone,

  I am trying to flash the latest flat build onto my Modal AI QRB5165 M hardware, but the process consistently fails.

  The initial connection via the Sahara protocol seems to work correctly, and the firehose programmer is loaded onto the device. However, the process fails as soon as it attempts to program the UFS storage. I have already searched the forums and found this highly relevant topic: https://forum.modalai.com/topic/4348/unbricking-of-voxl2-is-failing-build-failure

  Based on the suggestions in that thread, I have already tried the following:

  Running the qdl command manually with the --debug flag. Ensuring the libxml2 library is installed on my system. Using multiple different high-quality USB-C cables and different USB ports. Verifying that the flat build files were extracted correctly and are not in a nested sub-folder.

  Unfortunately, even after performing all these steps, the result is the same error every time.

  Given that the programmer loads but cannot access the storage, I am starting to suspect a hardware issue. Are there any other software-based troubleshooting steps I can try, or is this likely a case for an RMA?

  Any help or guidance would be greatly appreciated.

  Here is the key error output from the following command:

  sudo qdl --debug --storage ufs --include . prog_firehose_ddr.elf rawprogram_unsparse0.xml rawprogram1.xml rawprogram2.xml rawprogram3.xml rawprogram4.xml rawprogram5.xml patch0.xml patch1.xml patch2.xml patch3.xml patch4.xml patch5.xml

  Error output:

  @tonygurney , I am assuming that you are using the ESC hardware version M0134 (you can confirm using voxl-esc scan tool.

  Here is the datasheet for M0134.
  https://docs.modalai.com/modal-esc-datasheet/

  This ESC has an option (via installing a 0 ohm resistor) to provide 3.3V to pin 1 of J3. This is the same voltage that is used for the MCUs that run on the ESC and should be used with caution (if this voltage rail is brought down by overloading, the ESC will shut down). Please see image below that shows where 0 ohm resistor should be (carefully) installed to enable 3.3V on pin1 of J3 (marked in red)

  m0134-diagram.jpg

  If you actually wanted 5V (VAUX), that is available on the other side of the board via two test points at the edge of the board. This voltage rail is provided by a separate switching regulator. See the following section : https://docs.modalai.com/modal-esc-datasheet/#neopixel-led-support

  If you REALLY need 5V to be present on pin1 of J3, then you can add a small wire jumper from the VAUX test point directly to the pin1 of J3 (which is marked with a white dot). This pin 1 of J3 is normally disconnected. Please only do this if you are comfortable performing this type of soldering and we cannot guarantee the results :).

  @mrawding good afternoon, i see that your topic is quite old, but I am struggling with px4 firmware build and was wondering if you ever managed to successfully build your px4 firmware ? If you have done it recently, I would appreciate a helping hand in this topic: https://forum.modalai.com/topic/4539/voxl2-hitl-sim-with-gazebo-in-docker-vtol-frame-support/13?_=1751379111988

  @Cody , please double check the actual and desired roll / pitch / yaw values in the flight review. When the vehicle is level, then roll and pitch should be close to zero and desired roll/pitch will be zero as well if you don't touch RC sticks.

  If the attitude estimate is incorrect (for whatever reason) this can cause the vehicle to not be level during flight / take-off.
