MF 07:00 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

Hi Samuel,
Did you follow the instructions here and are still seeing this issue: https://support.criticallink.com/redmine/projects/mitysom_a5/wiki/A5E-DMA-Example#The-application-hangs-or-reports-errors-on-the-second-and-later-runs

SP 06:56 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

We have tried the new DMA driver and FPGA.
We have the following situation on each reboot.
The first test pass.
The second and third test fail.
The fourth hangs.
Is it expected behavior ?
Thank you for your time,
Samuel :)... Samuel Paul

Max,
That is correct! And check out my latest updates to the Wiki page for it as well: https://support.criticallink.com/redmine/projects/mitysom_a5/wiki/A5E-DMA-Example
Let me know if you run into any issues!

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

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.

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

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

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,

Hi Max,
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.

Is there a way to build it inside the docker container at the same time we build the file system.
