Hi @Jetson-Nano This page compares on-board support for all of our products. https://docs.modalai.com/voxl2-feature-matrix/#specifications You'll see Voxl2 has 128GB of on-board UFS Flash Yes, you can expand Flash size by using our J5 expansion port SDCC (or UFS1) interface. https://docs.modalai.com/voxl2-connectors/#j5---high-speed-board-to-board-connector-hsb2b We have some plug-in boards that expose these for development, but otherwise you need to make a custom plug-in board for your needs. Let us know if you need any extra help here. Thanks!

Hi there, looks like there's some confusion with what mode is being tested. Here's some clarification. PX4 has 2 approaches to handling obstacle distance data: a. Obstacle Avoidance(OA) feature which stops the aircraft if object detection occurs from the voxl-voa service. This requires CP_* parameters set that you can compare with your drone listed here based on your application. b. Collision Prevention(CP) feature, which not only includes OA, but also rerouting capability in all autonomous modes (position, alt, mission, offboard) and leverages the same voxl-voa service. This requires not only the CP_* parameters but also requires COM_OBS_AVOID = enable. If your application requires (a), you can leave com_obs_avoid = disable and OA should work out of the box as is. If your application requires (b), then we have discovered a software bug in the VOA service. And the main reason you get the "collision module not ready", no arm possible. It has been corrected [code here] and binaries will be available in our gitlab daily builds shortly.

@Moderator Got it. I have mailed already to contact@modalai.com . Please expedite my request and let me know.

@tom Sure, Thanks it worked out.

Can anybody find out the problems? Many thanks.

hi @Siddhanth to ssh onto the voxl you will need the IP address of the voxl. This means you will need to setup wifi on the voxl and then acquire the IP address. Once you have the IP address, you can run the command as in the image you posted above and the default password is oelinux123: ssh root@<IP ADDRESS>

@Moderator Thank you for responding in the repo where can i find the config file like in the source or tools can u pls help thank you the doc say's this Reset VIO resets vio to (0,0,0). Please do not reset in flight, only do this when it is safe and necessary

Hi @wilkinsaf Thank you for this post! I had the same issue and was able to solve it using these steps.

@Denver-Hopkins We had other projects come up. But this is starting to creep to the top of our list. If you would like to fast track it, feel free to email me at andrew.wilkins@ascendengineer.com

@wilkinsaf Thanks for the follow up!

@Chad-Sweet More on this from the manufacturer: MIPI Protocol The product we use is 2lane MIPI. The MIPI interface includes 1 pair of source-synchronized differencing clocks and 2 pairs of differencing data lines clock signals, which enter the high-speed mode at the beginning of each frame and exit the high-speed mode at the end of each frame. The interframe is in low power mode (both data and clock line are at 1.2V high level). MINI2-640, for example, uses a clock frequency of 400MHz. The data line sends the start packet of each frame at the beginning and the end packet of each frame at the end. The number of long packets between the start and end packets of each frame is the same as the height value of the array (such as a 640 * 512 module with 512 long packets), and each long packet data contains row valid data.

@Moderator I'm using a straight out of the box Starling.. with updated software..

@James-Strawson Quick update. I was able to lower the value to 300 and it seems to work as well.

Hi @AndriiHlyvko The chip is not infinity flexible. Many things are fixed/set in hardware meaning either the silicon device or the PCB. There is no internal cross-bar in the QRB5165 that allows for 100% remapping like on FPGAs. Please see these pages: https://docs.modalai.com/expansion-design-guide/#qups-the-key-io-groups-for-expansion https://docs.modalai.com/voxl2-qups/ Hope that helps explain things a little.

@tom Thanks a lot for the reply.

@AP123 Cool, check out that unbricking guide, that should fix your issue.

@Chase-Riley Okay, thanks for the update. I'll have to add an option to ignore the protocol byte check in the Spektrum driver then.
