we put the camera module connect to PC,it's ok

Was it a USB camera? If that's the case, you can use the USB camera on AM62A as well.

use below code ,and mask i2c operation(camera KKC.A002.32 no need to config)

Why did you use IMX219 driver for your KKC.A002.32? Do you have the driver for this camera?

Regards,

Jianzhong

not usb camera, soc+fpc+camra(isp+sensor),no have driver for this camera,so I use imx219.c

How did you connect your camera to the PC?

I don't think you can use imx219.c for this camera. You'll need to have a driver for this specific camera.

I have already use imx219.c to get the picture,the problem should be camera's timiming

yavta -s 1920x1080 -f UYVY /dev/video2 -c125 -Fframe-#.bin,maybe this command can tell soc the picture format by paramter -f UYVY 

when I use no set format,like below, I see yavta.c default format is YUYV

yavta -s 1920x1080 /dev/video2 -c125 -Fframe-#.bin ,after I get the picture,I use 7yuv ,must setting YUYV,the picture is normal

and can you tell me  can I use yavta to check fps of capture? 

yavta -c -Fcapture -s 1920x1080 -f UYVY /dev/video2

^C[ 1075.424812] ti-udma 4e230000.dma-controller: chan0 teardown timeout!

How did you connect your camera to the PC?

PC+ convert machine + fpc+camra(isp+sensor)

Please use "YUYV8_1X16", "UYVY8_1X16", etc, instead of 2X8, in your sensor driver. TI's CSI RX driver doesn't support 2X8 formats, because 2X8 is not a valid format for CSI.

thx,I got it

two question:

1.So I must use MEDIA_BUS_FMT_UYVY8_1X16 instead of MEDIA_BUS_FMT_UYVY8_2X8,

also other yuv format should use 8_1X16, like YUYV->MEDIA_BUS_FMT_YUYV8_1X16?

2.when soc start to capture,when soc send stream on , probability 1 or 2 picture is green,Is there a way to avoid SOC here?

example capture 120 

yavta -s 1920x1080 -f UYVY /dev/video2 -c125 -Fframe-#.bin

fist or second frame is green

You can use other YUV formats as long as they are 8_1X16. Please refer here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/media/platform/ti/j721e-csi2rx/j721e-csi2rx.c?h=ti-linux-6.1.y#n138.

Does this happen every capture, or just after a power cycle?

Green pictures mean the camera data buffers have all 0's. That most likely means your camera wasn't streaming in time when you started yavta capture. You'll need to check your sensor driver.
