Monaco EVK board does not include a camera sensor in its default hardware
configuration. Introducing a device tree overlay to support optional
integration of the IMX577 sensor via CSIPHY1.
Camera reset is handled through an I2C expander, and power is enabled
via TLMM GPIO74.
An example media-ctl pipeline for the imx577 is:
media-ctl --reset
media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy1":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video1

On the current master tip, I am seeing an unrelated issue where RB4 fails to boot due to a rootfs mount error. From next time, I’ll include the exact SHA on which the patches were validated. Rootfs mount error log snippet: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) [Firmware Bug]: Unable to handle paging request in EFI runtime service [ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) ] -- Regards, Nihal Kumar Gupta
