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. Nathan Olson

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.
Than... Noah Zins

Hi Nathan,
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... Noah Zins

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. Nathan Olson

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

I'm making some progress, but still not seeing an attempt to probe my sensor. I am seeing attempts to probe imx577, imx415, and... Nathan Olson

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?) Nathan Olson

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,

NZ 03:55 PM Software Development: RE: Streaming from 5 cameras simultaneously

It should be possible with the hardware, but currently our BSP uses Qualcomm Linux 1.5 that does not support it. Upgrading to version 1.8 is supposed to be the fix, but I noticed the release notes stated issues with multicamera streaming... Noah Zins
