        你好,我现在想尝试编译贵司的设备树文件,相机是raw-mipi-sc132,用的dts源文件是这个目录~\nvidia_jetson_veye_bsp-master\dtbs\Xavier-NX\JetPack_5.0.2_Linux_JETSON_XAVIER_NX_TARGETS\dts dtb\MV-MIPI-CAM,请问使用的对嘛?
        有详细在内核源码添加设备树源文件并编译的文档吗?方便提供下吗。

          @lb 对的。
          详细步骤参考:https://wiki.veye.cc/index.php/VEYE_CS_Camera_source_for_Jetson/zh

            @veye_xumm 有个问题咨询一下,2lane的mipi传输速率最大是1.5Gbps吗?我现在输出8位的10801280raw,每幅图数据10801280=1382400字节,如果是最大帧率120,这个传输能否支撑得了?

              @lb 当然没问题,根本用不了那么大的带宽。
              你试试应该继续算下去,10801280120*8bit.
              现在sensor的模式配置的是1.188Gbps/lan。

                  @veye_xumm 还是关于mcu的,SDA模式下,我猜想两种可能:一是数据先到mcu,mcu再给sensor,mcu只是做了透传。二是mcu和sensor作为i2c从设备直接挂到nx i2c总线上。请问是其中的某个情况吗?还是别的一个大致的概述呢?

                    这几款暂时还没有产品。

                      @veye_xumm 关于编译设备树的,按照https://wiki.veye.cc/index.php/VEYE_CS_Camera_source_for_Jetson/zh
                      做了。以下是我的操作:
                      export LOCALVERSION=-tegra
                      export ARCH=arm64
                      export TEGRA_KERNEL_OUT=/home/lanbao/nvidia/nx_kernel/ok
                      export KERNEL_PATH=/home/lanbao/nvidia/nx_kernel/ok
                      export XAVIER_DTS_PATH=/home/lanbao/nvidia/nx_kernel/hardware/nvidia/platform/t19x
                      export CROSS_COMPILE_AARCH64_PATH=/usr/local/arm
                      export CROSS_COMPILE_AARCH64=/usr/local/arm/bin/aarch64-buildroot-linux-gnu-
                      export CROSS_COMPILE=$CROSS_COMPILE_AARCH64
                      export COMMON_DTS_PATH=$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/nvidia

                      sudo sudo apt install git
                      git clone https://github.com/veyeimaging/nvidia_jetson_veye_bsp.git

                      export RELEASE_PACK_DIR=/home/lanbao/nvidia/nx_kernel/nvidia_jetson_veye_bsp
                      patch -p1 < /home/lanbao/nvidia/nx_kernel/nvidia_jetson_veye_bsp/kernel_patch_4_mv/l4t-r35.1/veye_mv_l4t_35.1.patch
                      366307f8-1ece-4aa0-988c-4ecadfe49636-image.png
                      ./nvbuild.sh -o $TEGRA_KERNEL_OUT
                      087b58b4-4164-42ab-b3bd-c1cea5917035-image.png
                      编译树:
                      cp /home/lanbao/nvidia/nx_kernel/nvidia_jetson_veye_bsp/dtbs/Xavier-NX/JetPack_5.0.2_Linux_JETSON_XAVIER_NX_TARGETS/dts\ dtb/common/t19x/* -r $XAVIER_DTS_PATH/

                      cp /home/lanbao/nvidia/nx_kernel/nvidia_jetson_veye_bsp/dtbs/Xavier-NX/JetPack_5.0.2_Linux_JETSON_XAVIER_NX_TARGETS/dts\ dtb/MV-MIPI-CAM/tegra194-p3509-0000-a00.dtsi $XAVIER_DTS_PATH/jakku/kernel-dts/common/

                      export COMMON_DTS_PATH=$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/nvidia

                      make ARCH=arm64 O=$TEGRA_KERNEL_OUT dtbs
                      得到设备树
                      $COMMON_DTS_PATH/tegra194-p3668-all-p3509-0000.dtb

                      然后将编译的树(只替换树),移植到NX路径/boot/lb,修改extlinux.conf 增加FDT新设备树路径。

                      问题:tegra194-p3668-all-p3509-0000.dtb此设备树无法启动jetson Linux。内核源码是自己对应jetpack版本下载的,都是OK的。能否给出一些指导意见。

                        @lb 如果你使用的Xavier nx是nVidia官方的,建议你直接使用我们提供的编译好的版本。
                        如果你确实需要重新编译,建议你替换dtb的时候,同时安装ko。然后引出启动串口的打印信息找一下原因。
