hello dakejahl,
since you’re testing with v4l2 IOCTL, besides to apply a patch to revert faulty DT settings, you’ll also need to revise mode definition for loading 4-lane configure.
for instance,
$public_sources/kernel/nvidia-oot/drivers/media/i2c/imx477_mode_tbls.h
static const struct camera_common_frmfmt imx477_frmfmt[] = {
{{3840, 2160}, imx477_30_fr, 1, 0, IMX477_MODE_3840x2160_30FPS_4LANE},
{{1920, 1080}, imx477_60_fr, 1, 0, IMX477_MODE_1920x1080_60FPS_4LANE},
please also add some debug prints within sensor driver side to check it’s loading correct mode settings.
hello rapidproto,
that’s strange, we’ve tested dual IMX219 on Orin Nano, it worked normally.
please have another new discussion thread if you need further supports.
