  I am trying to run two FLIR Boson 640 USB cameras simultaneously on VOXL 2 Mini.

  When I plug a camera into J9 USB-C port, I don't see it recognized as a USB camera device under lsusb. I can't seem to start voxl-uvc-server, etc. Normally when plugged into J3, I see the camera show up as ...FLIR Systems...

  Is the USB OTG functionality on VOXL 2 Mini supposed to work automatically? That was my understanding based on my forum research.

  Also, one interesting thing to note is that when I plug in the Boson to J9, I do actually see two more entries listed in lsusb, but they're not what I expect. The two entries are both "Linux Foundation root hub"

  Any advice? Thanks.

  I'm using VOXL2 I have connected the coax board to the voxl . when I screw the board on the drone firmly. the voxl boots up and works fine but I loose connection often. when I unscrew the voxl 2 and try to boot it. it doesn't boot. I have tried installing new SDK and downgrading it. no affect.
  this behaviour is very weard I can't understand what is going on and what could be the reason.WhatsApp Image 2025-03-25 at 01.05.03.jpeg

  @stevedan @bensusana I'm also facing this issue. Have you been able to solve this?

  @qqa , we have document how to achieve folder-level encryption on VOXL2 here : https://docs.modalai.com/enabling-file-encryption/ . Please let us know if you have any other questions.

  @Jetson-Nano It should be no different than with any other flight controller hardware running PX4. The PX4 documentation should be able to explain how to do that.

  Unbricked! Here's some context/advice for anyone trying to do the same. If you purchased a cheapo STLINK V2 from Amazon as I did. Picture below...

  $0 Fix:
  What may very well happen to ya, is the RESET pin doesn't work. In this case you will need a friend. With said friend, you must dilligently connect to the board using Under Reset Mode and Hardware Reset. The second your homie clicks the connect button, you, the bricker of the board must move your jumper cable from the RESET pin which is 3.3V to an open Ground, leave it for exactly 1 second, then move it back to RESET. This should work like a charm, but may require one or two tries to get the right timing. See instructions below.

  $10 Fix:
  Program a Pico/Arduino to do your 1 second ground for you.

  $78 Fix:
  Buy the real STLINK V2.

  Hi @Amir-Avni,

  Does your silkscreen on VOXL2 show M0154 or M0054?

  If M0054, it's 'hard coded' as an output only... behind a uni-directional level shifter.....

  If it's M0154, there's a directional level shifter in front of that GPIO that allows us to (with a kernel tweak) switch between UART and SPI.

  By default we are configured for UART use case, and the level shifter is set to allow an INPUT, by setting GPIO 67 low (as default), which is setup in device tree here, see "67" in modalai,gpio-init-output-low
  https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/v1.8.02/recipes-kernel/linux-msm/files/dts/common/m0xxx-modalai-gpio.dtsi?ref_type=tags#L12

  To enable VOXL2 J10 pin6 (gpio46) as an input, make sure gpio67 is set to low

  ok I found the problem...
  the Cube Serial inteface are driven by TXS0108E Level Shifter powered both side with 3.3 volt making it marginal for the Voxl Primary Serial interface. Switching to secondary interface on the Voxl made it work correctly.

  I sent a request for a change in the WIKI to reflect that configuration
