The CSI controller doesn't seem to work properly at the default clock rate of 600 MHz. Dropping it down to 300 MHz, the default rate used by the BSP, fixes things. The BSP also tries to use different clock rates (multiples of 108 MHz) according to the captured image size. I've not tried this since the driver no longer exports sub-device controls, and I currently don't know how to handle that to change the resolution. Regards ChenYu

I saw 1080p@30 capture is not working, but rest 320x240@30, 640x480@30, 640x480@60, 1280x720@30 with UYVY8_2X8 and YUYV8_2X8 seems working on 300MHz. I even tried 1080p on 600MHz but kernel seems crashing [video4linux2,v4l2 @ 0x2eaa9380] ioctl(VIDIOC_G_PARM): Inappropriate ioctl for device [video4linux2,v4l2 @ 0x2eaa9380] Time per frame unknown [video4linux2,v4l2 @ 0x2eaa9380] Stream #0: not enough frames to estimate rate; consider increasing probesize Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 44.934807, bitrate: N/A Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 1920x1080, 1000k tbr, 1000k tbn, 1000k tbc Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> mpeg4 (native)) Press [q] to stop, [?] for help Output #0, matroska, to 'output_YUYV8_2X8_1920x1080@1_30-new.mkv': Metadata: encoder : Lavf57.83.100 Stream #0:0: Video: mpeg4 (FMP4 / 0x34504D46), yuv420p, 1920x1080, q=2-31, 200 kb/s, 65535 fps, 1k tbn, 65535 tbc Metadata: encoder : Lavc57.107.100 mpeg4 Side data: cpb: bitrate max/min/avg: 0/0/200000 buffer size: 0 vbv_delay: -1 [ 45.255793] random: ffmpeg: uninitialized urandom read (4 bytes read) frame= 4 fps=0.0 q=10.0 size= 150kB time=00:00:00.10 bitrate=12162.7kbits/s speed=0.17x [ 46.115153] ------------[ cut here ]------------ [ 46.119804] kernel BUG at arch/arm64/kernel/traps.c:426!
