- Let me know if adding the pixel readout info to your XML made a difference.
Thanks,

- The other side is a long-wave infrared camera with a 16-bit parallel output. I have this setup working on an iMX.8MP SOM, so I know exactly what registers need to be written.

- Hi Nathan,
I saw you are using a tc358746 bridge IC. What is on the other side of it?
There is existing support for lt6911gxc and lt7911uxc bridge ICs, but they are for HDMI or DP to MIPI so I'm not sure if that is helpful.

When I did this I used tag r1.0_00095.0 for "Qualcomm_Linux.SPF.1.0|AP|Standard|OEM|NM_QIMPSDK", repo url https://qpm-git.qualcomm.com/home2/git/qualcomm/qualcomm-linux-spf-1-0_ap_standard_oem_nm-qimpsdk.git. It contains r1...

- Here's where I've gotten to. The sensor is probed successfully but there are a bunch of other errors that don't mean anything to me.

- After rolling @chicdk@ and @chicdk-kt@ back to @r1.0_00092.0@, I am able to successfully probe my sensor. Onward!

- Hi Noah, I'm trying to match the version you used for your camx modifications, but I can't find @r1.0_00095.0@. Any clues? (and where does @r1.0_00376@ fit in?)
- NZ 03:48 PM MitySOM-QC6490 Software Development: RE: Camera driver development
- Hi Nathan,
Did you see any different behavior with the power fields reinstated?
I noticed your sensor XML has no pixel/resolution information which I would think is necessary.
Thanks,

I just wanted to follow up and tell you that I have published a new DMA reference design to our repository and updated the Wiki page [[A5E-DMA-Example]]
Let me know if you have any questions regarding the updated design.

I too have noticed the probing of sensors 0-12, I have not looked into it but we see this same behavior. I expect your sensor to be 0.

I'm trying to bring up a new sensor, and no luck so far. To simplify things, I've removed all camera modules except mine, and removed all multicamera configs except mine, which has a single camera at cameraId 0, slot 0, ... - MF 03:31 PM MitySOM-A5 Software Development: RE: cl_msgdma.ko has the wrong version

We plan to integrate this kernel module into our kernel in the near future, so this would be handled automatically for the end user.
However, until then you could explore options such as adding a recipe into the Yocto bu...

Thanks for your response!

Nothing immediately stands out as to why you're having this issue (I have a project where I have success using this QUP for spi14 without issue).
