  • Motor desync at spin-up→closed-loop handoff — regression from previous firmware
    Alex KushleyevA Alex Kushleyev

    Hello @nostrain

    Please take a look at the ESC firmware changelog:
    https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/firmware/FIRMWARE_CHANGELOG.md

    • support for the M0138 FPV ESC has been added in firmware V39 RC10, which is likely what you received (i assume the ESC is reasonably old, since we are now shipping with latest firmware)
    • please note that only starting version V39.15, the ESC firmware sends back the exact version in format Vxy.ab -- so 39.00 could mean 39.10-39.15
    • also note that the firmware hash that you have (e4f576a0) is not listed in our firmware changelog, but it is essentially the V39 RC10 release (39.10).

    We will look into the changes. To help with this, are you able to share the approximate motor specs? (motor kv and what supply voltage you are using)? We can try to replicate.

    Are you able to test the firmware from this release and tell me how it behaves? https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/366d652e3680bb769d87dfca94f76b226481a6db/voxl-esc-tools/firmware . Initially we had a few releases that were not documented in the changelog (v0_39_RC10_a7f0bccb)

    Thank you

    Alex

  • Electrical Schematics of VOXL ESC Mini and VOXL 2 Mini
    VinnyV Vinny

    Hi @dakota_ltu Under an NDA we could consider the ESC. However, even under NDA, we cannot share the VOXL 2 Schematics unless the recipient is also a Qualcomm licensee with their own NDA with Qualcomm.

  • Evaluation of Starling 2 Max for Custom Onboard CV Project (4K MIPI, Onboard Inference, Zoom & Range Requirements)
    Alex KushleyevA Alex Kushleyev

    @sebastianp , sorry for the delay. There a lots of questions, let me start with what I can answer right away and will go from there.

    1. Hires Video

    Resolution:

    • Starling 2 Max comes with dual IMX412 cameras (front, down-facing). IMX412 maximum resolution is 4056x3040, which is larger than 4K. 8K is not supported on Starling Max. In general, we do have support for one 8K camera (OV64B), which has maximum resolution of 9248x6944 and that resolution is supported only at 10FPS. The only way to get that camera right now is part of a Flir Hadron combo (Boson + Color camera), which is probably not what you are looking for. So the best bet for Starling 2 Max is to use the provided IMX412 camera.
    • you can see some details regarding operating modes of IMX412 camera here : https://docs.modalai.com/camera-video/low-latency-video-streaming/#imx412-operating-modes

    Data Pipeline:

    • our camera server application (voxl-camera-server) can publish processed YUV images via shared ION buffers (zero copy) and the user application can receive those buffers for processing without any cpu overhead for doing inter process communication to send the image data.
    • you can also publish raw Bayer data (the exact data that comes from the camera) if that's what you mean by "raw"

    Optics:

    • no optical zoom is supported on any of our cameras, only digital
    1. Onboard AI Compute and Performance
    • I will need to check with colleagues and follow up.
    1. Flight Range, Autonomy & Control
    • Starling 2 Max used PX4 as flight controller, so all the standard flight modes are supported

    Answers to additional questions

    • Camera and Zoom integration: yes, raw and yuv frames can be shared with customer's C/C++ applications via shared buffers (or regular buffers via named pipes, which will have a lot of overhead for duplicating the data). No optical zoom is supported. Examples are available upon request
    • We provide voxl-cross docker image which can be used to build the projects for VOXL2. Majority of ModalAI packages that run on VOXL2 are built using this cross-complier environment and can serve as examples how to build your own applications (you can find most packages here : https://gitlab.com/voxl-public/voxl-sdk)
    • you can mount more hardware on Starling 2 Max, see the following thread regarding flight time : https://forum.modalai.com/topic/3732/starling-2-max-payload-capacity-and-flight-time-impact

    Frequency selection

    • when you configure your starling 2 max (https://www.modalai.com/products/starling-2-max) , you can select several options and the SKU will change accordingly. The page also has explanation for the different SKU options, so it sounds like you will need:
    • MRB-D0012-4-V4-C28-M11-T9-K2
    • C28 : dual tracking and dual hi-res cameras
    • M11-T9 : Microhard and Microhard pMDDL2450 and Ghost Atto (2.4Ghz)
    • it seems that this would be a custom SKU that you would need to request a quote for : https://www.modalai.com/pages/contact-us

    Ground Controller:

    • If the drone ships with an RC transmitter, it should be already bound to the receiver.
    • the controller and receive depends on the selection, see above regarding SKU and the shop page for more description
    • note that the RC controller has no ability to display video, so there is no out-of-the-box ability to stream video without additional setup, such as external computer, display / goggles, etc.

    I hope that answered a lot of your questions, please let us know additional questions or need clarification regarding anything else.

    Can you try upgrading to the latest VOXL SDK to see if that helps?

    Eric KatzfeyE Eric Katzfey

    I do not have a Windows computer handy so cannot really try Mission Planner. I tried to recreate this with QGroundControl but don't see it. Can you try with QGroundControl just to see what happens? Does it look like the 'systemctl restart voxl-ardupilot' is working reliably?

  • Version upgrade
    Alex KushleyevA Alex Kushleyev

    @royazriel ,

    We do not recommend doing apt upgrade, since we do not test this update method. If you want to update the SDK, you should do that following our SDK install instructions.

    As an advanced user, you may select to update your apt sources to use dev releases (basically latest dev branches) and selectively install packages that you want to test.

    The recommended SDK release for Starling 2 (Max) is 1.6.4

    With that in mind, please let us know if you have any more questions about this.
