    Hardware: (board / drone / SKU, serial # if you have it): voxl2 Software version: (paste the output of voxl-version [image: 1793578256101-6fc1e777-f5f4-45f8-9d3d-00e25c6d3b7a-image.jpeg] Configuration / services: (paste the output of voxl-inspect-services)bolded text What I am trying to do: 1. IMX412 Camera Frame Rate Configuration list itemCould you confirm whether the IMX412 camera’s frame rate can be set to 8.6 fps to match the operating frequency of our IR camera (Lenton)? list itemIf this requires modifications to the kernel or camera driver, could you provide instructions for building and flashing the modified software? list itemIs it possible to change the frame rate through software configuration after boot without modifying the kernel? 2. UART Configuration on the J3 Connector list itemCould you explain how to configure and enable the UART7 and UART13 pins on the VOXL 2 J3 connector for communication with an STM32? 3. Camera FSync Configuration on the J3 Connector list itemCould you confirm the GPIO assignment and control mechanism for outputting an FSync (Frame Sync) signal to a camera through the J3 connector? list itemCould you provide instructions for enabling the FSync signal, configuring its period, and applying the settings? 4. Clarification Regarding the Boot Mode Switches on the M0062 Board Our understanding is as follows: list itemFastboot is a bootloader mode used to install or update system images. list itemEDL is a low-level recovery mode used when a boot failure prevents access to Fastboot. The VOXL 2 includes Fastboot and EDL switches. We believe access to these switches may be necessary during development and operation in case recovery is required. Please refer to the image below for the connections between the VOXL 2 and the M0062 board. However, based on the M0062 board block diagram, the boot mode switches on the M0062 board appear to be unused. Could you confirm whether these switches are actually used and, if so, under what circumstances?

    On the Wi-Fi questions: The -M36 option ships with an Alfa Network AWUS036EACS (802.11ac AC600, dual band 2.4/5 GHz, Realtek chipset, made in Taiwan). It is listed on the Starling 2 Max datasheet. Yes, you can use a different USB adapter, as long as the VOXL 2 kernel has a driver for its chipset. You cannot install arbitrary vendor drivers without rebuilding kernel modules, so pick an adapter based on one of the Realtek chipsets we support: RTL8812AU or RTL8821CU / RTL8811CU. The adapters we have tested are listed on the VOXL 2 WiFi Setup page. If you find a Japan-certified (Giteki) adapter with one of those chipsets, it should work with voxl-wifi in both Station and SoftAP mode. If you cannot find a certified adapter with a supported chipset, another option is a USB-to-Ethernet adapter on VOXL 2 connected to a small Japan-certified Wi-Fi bridge or travel router on the drone. VOXL 2 only sees Ethernet, so there are no driver constraints. In SoftAP mode the default hostapd country code is US. For use in Japan, set country_code=JP in /data/misc/wifi/hostapd.conf after running voxl-wifi so the radio uses Japanese channel and power rules.

    Sorry @senja for the delays, this post did not get flagged for me. Yes, they install on different sides of the VOXL 2 board as shown here: https://docs.modalai.com/voxl2-connectors/#connector-callouts [image: 1792693889198-9a619597-c0ad-460a-b43a-c0689c8a0aab-image.jpeg] https://docs.modalai.com/M0226/#overview [image: 1792693659205-3064b401-56ca-4e7d-973c-0fe9c3ebe5cc-image.jpeg] https://docs.modalai.com/m0062-datasheet/#connector-callouts [image: 1792693766032-bc42a15b-8021-47f4-a9b6-534603ed8399-image.jpeg]

    Thanks Tom and Eric, finally resolved this, it ended up being a power supply issue. The unit we used to typically run it on the bench seemingly browned out somewhere in the flashing procedure.

    Hello. Can a Starling 2 drone autonomously fly while flying over the pipe inside a sewer? The drone must fly autonomously in a dark place to inspect cracks or internal conditions while flying along the water pipe. I'm not sure if this feature can run on Starling, so I'm asking for help!

    Hello everyone, I am looking for some expert advice on a VOXL 2 companion computer setup for a long-range platform. I have two main integration challenges: Challenge A: VIO at Higher Altitudes To solve the motion blur and pixel density issues at higher altitudes, I am planning a 6-camera configuration. I want to use 4 downward-facing sensors (2 daylight + 2 IR) equipped with narrow-angle lenses, alongside 2 standard wide-angle sensors (front and rear). Could you advise on the best supported sensors (e.g., IMX series) for this? Has anyone successfully tuned the voxl-qvio-server for narrow-angle lenses, and what were the altitude limits you achieved? Challenge B: LAN Integration & WireGuard The payload data flow will be: External RTSP Camera -> Ethernet -> VOXL 2 (WireGuard encryption) -> Ethernet -> Digital RX. Because VOXL 2 lacks multiple LAN ports, I will need a miniature industrial Ethernet switch. Does ModalAI have any tested hardware recommendations for this? Furthermore, what is the best practice for routing this VPN traffic through the VOXL 2 Ubuntu environment without bottlenecking the CPU? We are currently evaluating the VOXL 2 for a broader fleet deployment and want to ensure the ecosystem can support this custom optics requirement. Any feedback on off-the-shelf solutions or standard configurations for this use case would be greatly appreciated. Thank you!
