    • RE: Dual IMX412 connected to VOXL 2

      Adding more context for my last message:

      The voxl-sdk that you should install should be the latest from our 0.9 platform release. You'll have to download our latest platform release (VOXL2 Platform 0.9) from our downloads page. From there you can find the platform release under:
      Protected Downloads -> VOXL 2 Platform Releases -> VOXL2 Platform 0.9

      From there download the pacakge, untar the package, and navigate to the voxl-suite directory within the package (voxl2_platform_0.9/voxl-suite/). From there run the offline-install.sh script and this will install the voxl-sdk ontop of the beta system image that you previously flashed on target.

    • RE: Dual IMX412 connected to VOXL 2

      Hello @vipul-kadam ,
      We've now released a Beta System Image which should support the 2 IMX412 camers on the M0084-1 on camera group 1 (J7). Once you download the system image, you'll have to reinstall the voxl-sdk again as the download will only install the system image.

      Your camera server configuration file (/etc/modalai/voxl-camera-server.conf) for only two imx412 sensors connected would look as such:

      {
              "version":      0.1,
              "cameras":      [{
                              "name": "hires1",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    0,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       640,
                              "snapshot_height":      480
                      }, {
                              "name": "hires2",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    1,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       640,
                              "snapshot_height":      480
                      }]
      }
      

      Note that even though you are using IMX412, the camera type will still be IMX214 in the configuration file. Please let me know if this works for you.

    • RE: some general questions / issues with voxl2

      Hello @mark ,

      Regarding:

      Furthermore we are trying to use 2 hires camera's (imx214, and imx412) on the voxl2, but we are unsure how to do this. We tried copying the configuration file of 1 hires, and changing the cam_id, name, and type (in /etc/modalai/voxl-camera-server.conf). This results in an error saying the imx_412 is not a correct type. Configuring it as a imx214 gives a segmentation error. is it possible to configure 2 hires camera's on the voxl2?
      

      We've just released a Beta System Image which will allow dual hires camera's. Previously, you could only have an IMX214 sensor on camera hardware ID 3, with the beta release, there is now support for either IMX214 or IMX412 on camera hardware ID's 0, 2, 3, and 4. For more information on the camera ID's refer to this VOXL 2 Camera Configs image showing the camera ID's. The only limitation is that you can only have 2 hires cameras (any combination of imx214 or imx412) running at once. You can still run 2 hires cameras + any other sensors.

      Since this hires config is not yet standard, you will be required to create a custom camera configuration file. This will be located under /etc/modalai/voxl-camera-server.conf. For example, if you only have two hires cameras connected, your config file would look something like this:

      {
              "version":      0.1,
              "cameras":      [{
                              "name": "hires1",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    0,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       3840,
                              "snapshot_height":      2160
                      }, {
                              "name": "hires2",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    1,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       3840,
                              "snapshot_height":      2160
                      }]
      }
      

      Note that the camera type will be imx214 regardless of if the camera is imx214 or imx412.

    • RE: Dual IMX412 connected to VOXL 2

      Hello,

      Currently this is not supported on our latest platform release (VOXL2 Platform 0.9), so we're working on getting a build that will support this. Is there a camera configuration that you're targeting or would any setup with dual IMX412 support work?

    • RE: full-flash.sh occur Last flash failed:Volume Full

      Hello,

      I'm assuming the issue here is that your RB5 had a 14.1a chipcode system image already flashed. The system image you are trying to install is 9.1 chipcode based. The difference is that the 14.1a chipcode system image contains a new partition layout which is most likely why you're seeing the Volume Full issue.

      14.1a chipcode system images come with the voxl-sdk. You should install the latest RB5 Platform 1.3.1-0.8. Let me know if you see any issues with this.

      Hello,

      Just an update, I was able to fix the patching issue. You can go ahead and try the build again and see if the issue persists.

    • RE: Error/failure in voxl-build ...

      Hello,

      There was a recent kernel update that includes this patch which is most likely why the build has failed. I'll have to test this on my end and see what the issue is. I'll keep you updated as I see why the error is occuring.

      Also, just to confirm, are you currently up to date on the master branch?

    • RE: Voxl2 Wifi not working

      Hi,

      When running lsmod I would expect to see a list of different kernel modules including the 88XXau kernel module which is the driver for that wifi dongle. Luckily we've also included the kernel module in the Voxl2 file system under the path: /lib/modules/4.19.125/kernel/drivers/net/wireless/88XXau.ko
      I would suggest first trying to load this kernel module using the insert module command:

      insmod /lib/modules/4.19.125/kernel/drivers/net/wireless/88XXau.ko
      

      You should then run ifconfig and see if the wlan0 interface appears, if it does then the module has been successfully loaded and you should now be able to use your wifi dongle.

      However, I do recommend upgrading your system image by installing our newest 1.3.1-0.8 platform release. This will upgrade your system image to 1.3.1 and install the 0.8 SDK. This can be found on our downloads page. I recommend doing this because for some reason all your kernel modules are missing. I'm not sure what might've caused this, but it might lead to other issues.

    • RE: Voxl2 Wifi not working

      Hello!

      The driver for this wifi dongle should already come installed on Voxl2. It might be the case that you have an older system image that might not include this driver. Which system image do you have installed? You can check this by running the following command on the Voxl2:

      voxl-version
      

      Also can you send the output of:

      lsmod
      

      This will print out which kernel modules are loaded on the Voxl2.
