Adding onto this, is there a way to get the server to log out which operations/how many operations were delegated to the CPU? I believe its something that the tflite interpreter can spit out and would be super useful when trying to figure out why a model isnt loading correctly.

Hi,
Trying to run the IMX412 with the VOXL2 and have followed many of the threads regarding getting it to work. Ive gotten close but am running into a main problem. The camera is being noticed when running voxl-camera-server -l but it isnt being counted as a valid one. What am I missing here?

voxl2:/usr/lib/camera$ voxl-camera-server -l

The server-config:

voxl2:/usr/lib/camera$ cat /etc/modalai/voxl-camera-server.conf
/**
 * voxl-camera-server Configuration File
 *
 * Each camera has configurations for up to 4 HAL3 streams:
 *    - `preview` stream for raw unprocessed images from CV cameras
 *    - `small_video` 720p (ish) h264/h265 compressed for fpv video streaming
 *    - `large_video` 4k (ish) h264/h265 for onboard video recording to disk
 *    - `snapshot` ISP-processed JPG snapshots that get saved to disk
 *
 * on QRB5165 platforms (VOXL2 and VOXL2 mini) you can only have 3 of the 4 enabled
 *
 * This file is generated from default values by voxl-configure-cameras.
 * Do not expect arbitrary resolutions to work, the ISP and video compression
 * pipelines only support very specific resolutions.
 *
 * The default video compression mode is cqp or Constant Quantization Parameter
 *

Hi,
Are there any updates for getting Ubuntu 20.04 or above on the Voxl2. 2 years ago it was stated that it would be getting released soon, is that still the case?

Update on operating system upgrades to 20.04, 22.04 and 24.04

@Peter-Milani Nothing available for the public just yet but I can tell you we're working extremely hard on this and hope to start publishing builds soon

I'm also facing this after updating. Worked on an older version but it is now defaulting to the link local. One thing I noticed is that it doesn't go through the connection process (finding the network, trying password, etc) when using voxl-wifi, just skips all of it:

Configuring station mode...
Detected WiFi interface: wlan0
NetworkManager not installed, using legacy wpa_supplicant/hostapd
stopping softap mode
Enabling station mode on wlan0 (legacy)...
creating wpa_supplicant configuration for station mode
Station mode enabled on wlan0
Station mode configured!

This is using the MCBL-00022 kit on the voxl2.

Downgrading to 1.6.2 and the wifi works but seems a bit bugged because it cant find it at first even though it connects successfully :

Detected WiFi interface: wlan0
Disabling all WiFi modes...
Detected WiFi interface: wlan0
Scanning for network 'xxx'...
Scan succeeded, looking for network 'xxx'
Could not find network 'xxx' in scan results - proceeding anyway
Enabling station mode on wlan0...
creating wpa_supplicant configuration for station mode
Station mode enabled on wlan0
Station mode configured!

@tom Do you have any tips/tricks for getting the SNPE working on the current build?

Anyone have any ideas in regards to this?

• Software: Suite 1.5.0, System image 1.8.04
• Hardware: Voxl2: TF-M0054-4-V1-C11
• Factory setup of default software

Hi all,
I need to get access to SNPE (Qulacomm's Neural Processing SDK) and was wondering if there is a guide or anyone has any advice getting the library setup on the Voxl2. Current releases of SNPE only support python3.10 and ubuntu 20.04 which these boards are not running. I managed to find a previous release (2.24) that is python3.6 based but still the later version of Ubuntu. Is this something that can be done or am I digging myself into a hole?

Best,
Filip
