Update:
So for anyone who is facing the same problems as me.

1. If you want to train using tf2 you can't really take models form tf1 model zoo because tf2 feature extractors are not for the ones in tf1(even if tensorflow mentioned that you can use every tf1 model for later versions maybe outdated)
2. So for tf1 Model Zoo go with tf1 1.15.1 for tf2 Model Zoo just take the newest tf version
3. For tf2 take a ssd model from tf2 model zoo(ssd is only supported in export for tflite use)
4. (Expected that you set up model zoo dir and installed all pip packages for them):
   4.1 go to models/research/object_detection
   4.2 .use export_tflite_ssd_graph.py
   4.3. use the code mentioned in the docs from modalai to make tflite model
   4.4 put the tflite model on the voxl
   4.5 cd to the dir where your_model.tflite is type:

mv your_model.tflite /usr/bin/dnn/ssdlite_mobilenet_v2_coco.tflite

Why renaming the model?
Somewhere i Modal AI Code for tflite server theres a line that only take model with the name.
If your not renaming it you will get a (Model is not supported Error).
4.6 Replace the classes in the file beyond with your classes

vi /usr/bin/dnn/coco_labels.txt

4.7 Run tflite Server
For me that worked with SSD MobileNet v2 320x320(don't get confused its actually 300x300 don't know why) from:
https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2_detection_zoo.md
with the base model given there. Ill have to see if it really works after training.
I will probably make a github repository in the Future when i have time featuring:
+setting up tf2 and tf1 on your local machine with gpu
+training
+export tflite and put on voxl
because it was such a pain in the ass to setup all this when not being familiar with machine learning, and poor documentation.

@Philemon-Benner Seems like some else had the same issue but there was no further investigation on the problem. https://forum.modalai.com/topic/2125/voxl-mavlink-server-external-fc-bus-error?_=1688565579723

Hey,
i am trying to move to new voxl-mavlink-server. After upgrading, when running voxl-mavlink-server i get the following error:

After that error the device goes offline, and i have to powercycle the Voxl in order to access it again. I configured voxl-mavlink-server with voxl-configure*. I am migrating from voxl-mavlink-server v0.3.0 wich runs perfectly fine, i also tried using a different Voxl but same issue persists.

voxl-mavlink-server: v1.2.0
libapq8096-io: 0.6.0
system image: 3.8.0 / 4.0.0
hw version: VOXL

Hey,
i want to upgrade voxl-cross to 2.5 with voxl-docker, but unfortunately new proprietary ipk and deb packages are missing in Modalai protected downloads.

apq8096-proprietary_0.0.4.ipk
qrb5165-proprietary_0.0.3_arm64.deb

are they store somewhere different from the old location ?
If not would be nice i you could add them.

@Chad-Sweet what is the reason for using Gralloc allocator on apq8096 for buffer allocation instead of ION memory allocator used in the qrb5165 implementation ?

Thanks for the fast reply

Hey,
i want to integrate the https://docs.modalai.com/M0025/ Camera from you in my application. I'm currently using opencv to capture video frames.
Is it required that i use the hal3 module used in https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/tree/master/ ?
If yes wich libraries do i have to link to my application in order to use the hal3 module ?
And can i build these on my own or are these built alongside the system-image ?

Platform: Voxl 1 ap8096

@tom Now it's working again, but might be worth a look, it's important that it always works. Parsing seems fine:

apq8096 detected...
'v2'
len: 2

Initializing v2 modem...

Waiting for ttyUSB2...
ttyUSB2

Hey,
i'm currently trying to do something similiar to modallink_relink.py, but i need the return value of voxl-modem-start.sh and it should be blocking, so i wanted to directly run that instead of using:

systemctl restart voxl-modem

But when i'm running voxl-modem-start.sh from voxl terminal i get the following error:

the modem is configured and with the service file it works. I also tried playing around with the if conditions in voxl-modem-start.sh but without success.

System Image: 3.8.0
voxl-modem Version: 0.16.1

Hey,
i am using modal pipe and modal json in my project as external project , but sadly the cmake install path is always /usr/lib64, so i wanted to ask if i am allowed to fork modal pipe and modal json and create a public gitlab project including these, where i only change the cmake files ?

Also a list of country codes conforming the (ISO/IEC 3166-1) of the hostapd.conf:
Could be put into the print_usage:

echo "List of available Country Codes: https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes"
