QHY268C does not work

I'm trying the QHY268C.
QHY268C(PhotoGraphic Version) can be captured on Windows 10, but Ekos (INDI) has not succeeded in capturing.
When I capture with Ekos, I can capture the first one, but after that, the exposure is interrupted or the capture freezes.
Device I/O errors are logged in dmesg.
I want to use this camera, but it's too new and there is very little information.

I attach the Ekos log and the result of qhy_ccd_test.

INDI server is as follows
RaspberryPi4 with Ubuntu 20.04.1 aarch64
INDI & Kstars are all Nightly Builds versions

Please help me.

I also have QHY268C(PhotoGraphic Version) and installed with Stellarmate on RPI4B.
I have trouble with QHYCCD SDK ver.20.07.26 before. It is fixed with Stellarmate Beta nighly build with QHYCCD SDK ver. 20.08.26
Please check with QHYCCD SDK version in INDI QHYCCD panel.

@noriQ, in your log file you have a lot of DEBUG but I see ERROR here
[2020-09-15T23:04:18.875 JST INFO ][           org.kde.kstars.indi] - QHY CCD QHY268C-57ab4e4 :  "[ERROR] GetQHYCCDSingleFrame error (-1) "

I see the same thing with my QHY5III178C running with QHY SDK 20.08.26 with Kstars 3.5.0 Beta built on my Rpi4 (Astroberry) 2020-09-24.

This consistently happens (and gets worse with longer exposures) starting around 60 sec. exposures. Spec claims max of 3600 sec.

Sigh, more QHY SDK silliness. Maybe knro can query Dr. Q. for a fix.

Thank you for helpful advice.

I gave up using the QHY268C on my Raspberry Pi 4.
There may be a problem with the arm64 kernel (USB module?) Or the QHYSDK.
I decided to use an Intel stick PC instead.
QHY268C works fine with Ubuntu 20.04.1 amd64 kernel and QHYSDK 20.8.26.

Try entering the resolution 6252 x 4176.

That's what worked for me.
