Hi Dmitry,
Here is a successful run of the second 4000-OEM. This can provide some clue. To get our software to load and run, I had to leave the unit powered on (warm up), then I power cycled and our software runs ok.
Thanks, Kim

Hi Dmitry, Yes, this board works with 4.14 kernel.
Also, we can get the second 4000-OEM to crash when running our software if we power off the unit for a while (an hour) and then power the 4000-OEM back on. Attached is the failure log for this second unit. This board also runs 4.14 kernel successfully.
Thanks, Kim

Hi Dmitry,
This is the parameter file from the board that is having issues. You can copy it to the /home/slroot/sl/bin folder on your 4000. It is a single cam0 configured as a testpattern 1080p image.
Just to verify: does this board work with 4.14?
Can you try the link again? I changed permissions.
Thanks, Kim

Hi Dmitry,
With the latest patch for 5.15, both boards that didn't boot up now boot, but one of the two boards crashes when we run our software. Attached is the dmesg log.
This is interesting. I also noticed the following:
[ 44.186437] qcom-camss a34000.camss: Failed to add VFE#0 to power domain [ 44.186515] qcom-camss a34000.camss: Failed to power up pipeline: -22 [ 44.189179] qcom-camss a34000.camss: Failed to add VFE#0 to power domain [ 44.199654] qcom-camss a34000.camss: Failed to power up pipeline: -22
So, some parts of the board might be underpowered.
I will take a look, what can be causing this issue or how can we cope with that. In the mean time, could you please describe, which camera is enabled on this board?
With the latest patch for 5.15, we observe that the CPU functions (Analyze) is a little slower. We also observe that power usage has increased between 4.14 and 5.15: https://docs.google.com/document/d/1UD6FofrJKZ_9W7rGWTkN-DyoVI9KXQxkt E XY6eYpeUU/edit#bookmark=id.y65dtcn7w11x
I don't have access to this document.
Thanks, Kim

Hi Dmitry,
This was two weeks ago when I ran this, but I do not think so. Although we didn’t do any temp test in our freezer (room temp only), because we didn’t hear back from you on if this was correct. Should we?
I think you should create a single patch for us to test because the last patch you sent us did not compile, so I’m wondering if the correct patch was sent to us. In that patch, this line didn’t compile: dev_info(gpu: "GPU setting to %ld\n", *freq);
Please give a series of tests to the attached patch. I'm interested in:
- speed bins for the boards that crashed when you tested the previous version, check the following line in the dmesg:
[ 4.105174] adreno b00000.gpu: Detected speed bin 0
checking that GPU performance matches the expectations.
checking that the boards are stable in normal conditions and in the fridge test.
Thank you for your testing!
