V4l2 camera capture on imx6 cannot capture RGB24 correctly

makislivadas — Wed, 21 May 2014 23:28:06 GMT

Using SabreSD imx6q evaluation board and trying to capture data with V4L2_PIX_FMT_RGB24, and it does seem to work when I use the ipu_prp_enc.c. driver, however when I use the ipu_csi_enc.c driver the colours are quite wrong?

I seem to be able to get correct colour if I use the V4L2_PIX_FMT_YUYV pixel format when using both drivers.

Is this a known issue. I using kernel L3.0.35.

I have now build the latest Yocto based BSP with Linux 3.10.17 and the problem is still present.

It does seem to me that the ipu_csi_enc.c driver although it accepts V4L2_PIX_FMT_RGB24 capture format it does not seem able to support it properly. The only format that seems to work is V4L2_PIX_FMT_YUYV.
