Jetpck5.1.2 fpga devs 与orin nx 核心板通过mipi csi接口相连无法出图


我修改了nv_imx219.c 与 imx219_mode_tbls.h 与 tegra234-camera-rbpcv2-imx219.dts ,tegra194-camera-jakku-rbpcv2-imx219.dtsi,文件以适配硬件。
但是通过v4l2-ctl命令,调试出现VIDIOC_S_FMT:failed:Inappropriate ioctl for device, 并且和一些其他问题,能否帮忙找下原因,感谢。。。文件如下:

nv_imx219.txt (19.7 KB)

imx219_mode_tbls.txt (1.8 KB)
tegra234-camera-rbpcv2-imx219.dts.txt (7.3 KB)
tegra194-camera-jakku-rbpcv2-imx219.dtsi.txt (1.6 KB)

I would suggest having driver report one format a time and get the trace log to check if more clue.


i have a question, we use public/kernel/nvidia/drivers/media/i2c/nv_imx219.c,
but the kernel_src/driver/media/i2c/imx219.c ,,They have different V4L2 frameworks,
in imx219.c , it have set_fmt interface…

but nv_imx219.c , i dont know how to set fmt , it seems no interface to link V4L2 frameworks…


Capture failed from the sensor.
Get the trace log to check if more information.

i have done what you said, this is log file

how do i do next ??

Enable the log then run the v4l2-ctl to capture then cat the log by below command.

cat /sys/kernel/debug/tracing/trace
