Building the edited source code

[IC]

@Alex-Gardner Thanks for the clarification!

I'm following the instructions here to install the pre-built voxl-cross image but don't have the required directory.

Can I change the path to '~/bin/${RUN_SCRIPT}' in the script?

The docker images are not meant to be run on voxl, they're made to emulate the voxl's environment on a desktop computer. You should install the script and image on your desktop, build there, and then use the deploy script to send the built package over to a voxl via adb or ssh

[IC]

@Alex-Gardner Right. Thank you!

I'm trying to build the VVPX4 using the voxl-cross image on my desktop but I'm getting the following errors.

Any pointers to what I might be missing?

Did you run the install_build_deps script?

[IC]

@Alex-Gardner Yes, I did.

You should only be installing/building for one platform (both in general but especially within a single docker instance). APQ8096 is the processor on VOXL and QRB5165 is the processor on RB5 Flight/VOXL2.

For this specific issue though, it looks like you need to be pulling from the staging repo, not the stable one since you're building effectively the staging version of vvpx4 (stable would be on the sdk-0.7 tag). The function you're missing was added in libmodal-pipe 2.1.8 but stable has 2.1.7

@Alex-Gardner Right. Thanks a lot!

When deploying to VOXL, I'm getting the following message:

From what I understand the VVPX4 is not overridden by the new VVPX4 package pushed to the VOXL. Do I need to change the VVPX4 version in any of the scripts?

Ah that's the last issue, our latest stuff requires a tweak to the opkg environment to allow packages marked arm64 (we're so very close to releasing a new system image with this in it), if you add the line arch arm64 7 to /etc/opkg/arch.conf you'll be able to install the package you just built.

[IC]

@Alex-Gardner Apparently not the last for me!

So now the package is configured but not installed:

And VOXL does not connect to QGC now. I tried reinstalling the unedited package and get the same message and no connection to QGC.

@Alex-Gardner And factory resetting it

voxl-configure-mpa --factory-reset

shows the following:

I've uploaded the most recent platform release (3.8.0-0.7) for VOXL with a number of important changes to support our most recent stuff. If you flash this new platform and then deploy your custom VVPX4, there shouldn't be any more issues.

[IC]

@Alex-Gardner Great, thanks!

Hi,

I've been trying to deploy VVPX4 and still see some dependencies. I am using the VOXL Platform 3.8.0-0.7 and VOXL-Cross-2.1 docker image.

voxl-vision-px4-master $./deploy_to_voxl.sh 
searching for ADB device
checking VOXL for dpkg/opkg
opkg detected
voxl-vision-px4_1.2.0.ipk: 1 file pushed. 3.4 MB/s (105362 bytes in 0.029s)
Reinstalling voxl-vision-px4 (1.2.0) on root.
Configuring voxl-vision-px4.
Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for voxl-vision-px4:
 * 	libmodal-pipe (>= 2.4.0) * 	libmodal-cv (>= 0.1.0) * 
DONE

Maybe I have to build the following in a specific directory but I am not sure which one:

$ mkdir cross-workspace
$ cd cross-workspace
$ voxl-docker -i voxl-cross:V1.9
voxl-cross:~$ git clone https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-json.git
voxl-cross:~$ cd libmodal-json/
voxl-cross:~$ ./build.sh qrb5165

Can I install or source these two dependencies separately?
