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.
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.
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.
