      预览画面确实是黑色的。按照您的建议操作,删除lut_rw
      写入lutenable及lut的数据,重启后,读取的数据也是修改后的,但是预览画面确实是黑色的。
      难道树莓派平台github目录的sources无法直接与jetson平台中的sources直接替换?
      1)黑屏若是因为lut写操作一直没有成功过,那为何重启后我读取的lut文件中的数值与我写入的数值是一样的呢?

      另外我发现存在以下问题

      • 在没有开启预览画面的情况下,去修改lut文件,在打开预览模式,虽然显示是更新成功的,但是画面显示是黑色的,再次执行修改lut的命令,画面显示才不是黑色的

        忘掉以前的种种吧。
        请按照如下步骤,在jetson xavier nx上,一步一步操作:
        一、视频预览

        export WIDTH=1440
        
        export HEIGHT=1088
        
        export FPS=60
        
        v4l2-ctl -d /dev/video0 --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=UYVY
        
        v4l2-ctl -d /dev/video0 --set-ctrl frame_rate=$FPS
        
        gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)$WIDTH, height=(int)$HEIGHT, framerate=(fraction)$FPS/1" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nv3dsink sync=false
        

        二、调试lut

        1. 从这个github上下载最新的mv_tools_jetson
         git clone https://github.com/veyeimaging/nvidia_jetson_veye_bsp.git 
        

        如果由于某种原因下载不了,换个下载方式。
        2. 修改lut。

        cd mv_tools_jetson/i2c_tools/
        
        $ ./mv_mipi_i2c.sh -w -f lut -p1 ./lut_samples/lut_gamma1.2_10bitdepth.txt -b 9
        w lut from file : ./lut_samples/lut_gamma1.2_10bitdepth.txt successs
        
        1. 在lut使能和不使能状态切换。
         ./mv_mipi_i2c.sh -w -f lutenable -p1 1 -b 9 
        
         ./mv_mipi_i2c.sh -w -f lutenable -p1 0 -b 9 
        

        此时可以看到图像明显的变化。
        4. lut使能时,更换lut

         ./mv_mipi_i2c.sh -w -f lutenable -p1 1 -b 9 
        
        $ ./mv_mipi_i2c.sh -w -f lut -p1 ./lut_samples/lut_gamma1.2_10bitdepth.txt -b 9
        w lut from file : ./lut_samples/lut_gamma1.2_10bitdepth.txt successs
        
        $ ./mv_mipi_i2c.sh -w -f lut -p1 ./lut_samples/lut_gamma0.8_10bitdepth.txt -b 9
        w lut from file : ./lut_samples/lut_gamma0.8_10bitdepth.txt successs
        
        1. 读出lut曲线
        ./mv_mipi_i2c.sh -r -f lut -p1 ./readout_lut.txt -b 9 
        

        可以对比读出的./readout_lut.txt和上次写入的lut_gamma0.8_10bitdepth.txt文件一致。
        6. 参数保存功能

        ./mv_mipi_i2c.sh -w -f paramsave -b 9
        

        然后拔下电源重新上电。
        上电后读取lutenable和lut曲线:

        $ ./mv_mipi_i2c.sh -r -f lut -p1 new_lut.txt -b 9
        r lut and save to file : new_lut.txt 
        xumm@ubuntu:/dbg/mv_tools_jetson/i2c_tools$ ./mv_mipi_i2c.sh -r -f lutenable -b 9                
        r lut enable is 1 
        

        可以看到enable参数保存了,而且对比new_lut.txt 和./readout_lut.txt 完全一致。

          现在仍有问题
          下载最新的mv_tools_jetson,并执行上述指令,关机重启后,数据虽然保存,但是预览模式画面仍是黑色的,需要再次执行 ./mv_mipi_i2c.sh -w -f lut -p1 ./lut_samples/lut_gamma0.8_10bitdepth.txt -b 9 命令,画面才会显示出来。麻烦您这边复现一下问题,不知道您这边是否查看了预览画面的效果显示,可否给出一个最优的解决方案。十分感谢。

            断电不能生效是个bug,我们已经做了升级包来解决此问题,MV-MIPI-IMX296M_C1.28_L1.33_upgrade_20230328.bin。
            请参考这个文章下载升级包,升级。

              请问jeston平台的升级工具是不是mv_tools_jeston中的veye_upgrade?

                  Step 2
                  Using v4l2 driver mode, the power up and probe process will be performed during the linux boot process.

                  请问针对上述语句,我需要在jeston平台如何操作?

                    板子上电即可。
