Hello Loic,
I'm having some issues with RAW8 mode on the OV5640 camera and I'd like
to kindly ask for your advice, as I saw that you added support for RAW
mode in the mainline kernel driver.
I'm trying to capture some raw images on a i.MX6Q based board. I
configured the pipeline as follows:
media-ctl -l "'ov5640 1-003c':0 -> 'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
media-ctl -l "'ipu1_csi1':2 -> 'ipu1_csi1 capture':0[1]"
media-ctl -V "'ov5640 1-003c':0 [fmt:SBGGR8_1X8/2592x1944 field:none]"
media-ctl -V "'imx6-mipi-csi2':2 [fmt:SBGGR8_1X8/2592x1944 field:none]"
I'm capturing the frame using v4l-utils:
v4l2-ctl -d /dev/video5 --verbose --set-fmt
video=width=2592,height=1944,pixelformat=BA81 --stream-mmap
--stream-count=1 --stream-to=bggr_2592x1944.raw
The images I'm obtaining are completely garbled. I tried both 5.2
mainline and 5.1.18 kernels.
I'm able to correctly capture YUV frames in all resolutions with the
same driver (with the pipeline configured to go through the
ipu1_ic_prpenc node first).
Do you have any insight on what might be causing these issues? Is the
PLL configuration supposed to be changed when RAW8 format is selected?
Thanks for your help,
Best regards,
Laura
