Hi Dafna! This is sort of enhancement request to support MEDIA_BUS_FMT_Y8_1X8 and MEDIA_BUS_FMT_Y10_1X10 formats on RKISP1 media platform. I’ve got Radxa’s Rock Pi 4B, greyscale sensor raw camera supporting only above formats and a desire to extend format support. Actually I already tried to port these changes - https://github.com/JeffyCN/mirrors/commit/72e4ba0ccf477a6d90f40a2fb5e3bc9e5025093b to mainline kernel v6.1+, I was able to set up the pipeline and “start” streaming without getting Broken pipe error, but eventually it failed here - https://github.com/torvalds/linux/blob/v6.1/drivers/media/platform/rockchip/rkisp1/rkisp1-capture.c#L962 So if this kind of enhancement activity is of any interest to you or parties involved, let’s kick it! UPDATE: Sent plain text Cheers, Anton
