  For my senior Design Project, I am planning to develop a modular payload for my UAV (Modal AI Sentinel). My payload is a an Arducam IMX 519 camera sensor with a Camera serial interface connection to a raspberry pi computer which will then connect to the VOXL 2 thru USB-C. I want to ask whether this payload connection is appropriate and will not "brick" the system? The Arducam and Raspberry Pi will be placed on top of a plate connected with vibration dampeners to the Sentinel's airframe.

  Hi,

  Is it possible to connect to a WiFi network with VOXL-Flight on the 5 GHz band? VOXL seems to default to 2.4 GHz, even when the router offers 5 GHz (e.g., my laptop is connected with 5 GHz). I tried modifying the configurations in /data/misc/wifi/, including hostapd.conf (soft access) and sta-hostapd.conf (station mode), by setting channel=36 instead of 6. However, the drone continues to connect with the 2.4 GHz frequency.

  This is important as I have Spektrum RCs emitting at 2.4 GHz, which causes significant interference.

  Any hints?

  @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.

  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
