Request for QURT Compatibility for OSD Program

JP Drone

I am currently working on configuring the OSD program (msp_dp_osd) on VOXL 2 Mini. I have successfully confirmed that the OSD works using Pins 4/5 on J10 (/dev/ttyHS0).

However, Pins 4/5 on J10 (/dev/ttyHS0) are required for other critical purposes, and as a result, I would like to utilize J19 Pins 2/3 (SSC_QUP6) for OSD UART communication.

As these pins are connected to the DSP (SLPI processor), the current OSD implementation cannot access SSC_QUP6 directly because it requires QURT compatibility.

I kindly request that the OSD program be extended for QURT compatibility so it can function over SSC_QUP6 (J19 Pins 2/3). This modification would free up /dev/ttyHS0 for other critical tasks and allow more efficient use of the VOXL 2 Mini's available UART resources.

Thank you for considering this request. I look forward to your response and any guidance on potential workarounds or a timeline for implementing QURT compatibility for the OSD program.

@JP-Drone Okay, I will try to get it running on the DSP side to use J19. I'm guessing that you don't use GPS so it's okay to use that UART port for OSD? I should be able to complete this by the end of the year.

@Eric-Katzfey Thank you for your response.

Yes, that's correct. I don't use GPS for indoor flight, so it's fine to use that UART port on J19 for OSD.

I appreciate your support and look forward to the update.

@JP-Drone Can you try this voxl-px4 package and see if msp_dp_osd works for you on the GPS UART? You will need to add the driver start command in /usr/bin/voxl-px4-start. For example: qshell msp_dp_osd start -d 6. Download the package with wget http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.87-202412180935_arm64.deb or use the link http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.87-202412180935_arm64.deb

@Eric-Katzfey Thank you for providing the updated package.
I will test it within the next three days.
I’ll get back to you with the results shortly.
