I have made Sony sensor driver for the TX2 and I can’t seem to get exposure time longer than about 750 ms. I have noticed on all other cameras, which are supported by default, that the exposure time in Argus can’t be set more than about 1 second.
I need to get at least 5 second exposure times on image capture. Judging by the fact that the exposure settings work on my driver correctly and it just freezes when I set it to more than about 750 ms in Argus camera, for example - it probably has to do something with the Jetson. Is it something to do with ISP? I really need to get this to work.
Ok. Would you be able to share any specifics as to why it couldn’t be supported on the TX1/Nano? We may soon begin working on our own IMX477 driver modifications and using v4l2 directly for raw bayer access (bypassing nvargus-daemon), and would probably need to understand the reason why an infinite timeout doesn’t work on those particular chips. Any help you can provide would be much appreciated. Thanks!
Update - And since the source for nvargus-daemon isn’t available, it’s not currently possible to see how that enableCamInfiniteTimeout debug feature was implemented.
