Hi Kim,

There are a couple changes required here that will make this work:

1. Rebuilding Kernel with SPI14 enabled
You're going to have to rebuild and flash the kernel with QUP14 enabled as SPI. There is also a directional level shifter on GPIO67 that needs to be set to high in order for SPI on QUP 14 to work. I created this branch for you that should have the kernel changes that you need:

feature/voxl2-mini-spi-qup14 (link)

In order to actually build and flash the kernel please follow the instructions from our public docs on how to build the kernel

https://docs.modalai.com/voxl2-kernel-build-guide/

When building the kernel, after syncing but before building, make sure to go to the cloned meta-voxl2-bsp directory and checkout the branch that I created (feature/voxl2-mini-spi-qup14).

Also there is a chance you may need to build a kernel variant depending on your device so also make sure to check this document to see if you have a -2 device which would require building the kernel with the -v var02 flag

https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

2. Configuring Trustzone with Correct QUP
I would recommend using the devcfg binary that comes from the `voxl2-mini_SDK_1.0.0.tar.gz. In order to flash devcfg you'll want to run the following command

fastboot flash devcfg <path/to/voxl2-mini_SDK_1.0.0/devcfg>/devcfg.mbn

You should flash the kernel and devcfg (Trustzone) during the same fastboot session to avoid running into any issues with the device booting.

Let me know if you have any additional questions or run into any issues!

Thank you for the quick reply.
I will try doing as you instructed and post the results.

Thank you.
Kim

Thank you for your reply.

@Jskim , sounds good!

Just FYI, i noticed that the config file i provided has some outdated settings for IMX412 camera - I have some better suggestions and will follow up soon. You can still test with the above config - the hardware functionality will not be affected.

Finally, I tried a test.
I tried changing the video player and the Streamer died immediately.
The conclusion is that the Streamer died even when it was in the foreground.

Hi @Jskim
We are happy to report our testing was successful.
I have documented the process where you can modify MCBL-00022-2 and add the series caps for your self to unblock your USB 3 speeds:

https://docs.modalai.com/cable-userguides/#how-to-modify-mcbl-00022-2-for-use-with-voxl-2-mini-usb-3-speeds

Hope this helps!!
Let us know how your testing progresses.

@milanerd The added capacitance helps VOXL 2 Mini's USB port achieve USB 3 speeds. We don't have that adapter to confirm a fix for your issue, but with the cable the link should transfer much faster

@Vinny
Thank you so much.

Kim,

@Jskim voxl-uvc-server doesn't support that format. You would have to modify the code to add that feature.

Hi @Jskim
The use case for Modem support on VOXL 2 Mini is through the USB Host port, J3, as shown here:
https://docs.modalai.com/voxl2-mini-connectors/
We provide up to 900mA of 5V output on VBUS, so be sure your power needs can work within that limit.

I'm sorry I cannot answer the other question, so hopefully someone else from the team will respond and advise.
Thanks!

@Jskim Can you please open these new questions as new topics? That way the appropriate staff member can address them. Thanks!
