we’ve recently flashed a brand new Nano Dev Kit (B01) with JetPack 4.6 and configured its CSI ports to support IMX477 via the
jetson-io.py. The Raspberry Pi HQ Camera (with the resistor R8 removed) can be found by
v4l2-ctl and can also stream using
BUT it failed streaming using
v4l2-ctl. For streaming we used
v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw --verbose
v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw --verbose.
Only in few cases, it worked. In most cases, it just hanged. While hanging, there were constantly
video4linux video0: frame start syncpt timeout!0
errors logged in the Kernel log, which means that the frame start signal on the MIPI lane was not received by the driver (if I am not mistaken).
We’ve verified that both the camera and the MIPI cable are fine. Could you please suggest us what could be the cause to this problem and how to fix it? Any help will be appreciated. Thanks!
