VEYE CS Camera source for Jetson/zh

English

英伟达Jetson平台上VEYE和CS系列摄像头驱动源码编译指南

1 概述

1.1 版本对应关系

• Jetpack4.2.2,L4T版本r32.2.1
• Jetpack4.3,L4T版本r32.3.1
• Jetpack4.4,L4T版本r32.4.3
• Jetpack4.4.1,L4T版本r32.4.4

1.2 查看当前L4T版本

首先查看当前L4T版本，尽量使用同一版本进行替换。

cat /etc/nv_tegra_release

如显示:

# R32 (release), REVISION: 4.3......

则表示当前版本为32.4.3。

2 HOST开发环境准备

步骤参考：3.6.1 HOST开发环境准备。

以下操作均为在HOST PC进行。

3 下载我们的bsp包

cd $L4T_DIR

git clone https://github.com/veyeimaging/nvidia_jetson_veye_bsp.git

export RELEASE_PACK_DIR=$L4T_DIR/nvidia_jetson_veye_bsp

4 编译kernel

4.1 patch代码

cp $RELEASE_PACK_DIR/drivers_source/cam_drv_src/* $NVIDIA_PATH/drivers/media/i2c/

cp $RELEASE_PACK_DIR/drivers_source/kernel_veyecam_config_<l4t_version> $L4T_DIR/sources/kernel/kernel-4.9/arch/arm64/configs/tegra_veyecam_defconfig

4.2 编译

cd $L4T_DIR/sources/kernel/kernel-4.9/

make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_veyecam_defconfig

make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4

编译完成的Image文件在：

$TEGRA_KERNEL_OUT/arch/arm64/boot/Image

可以用于整体烧写，也可以用于动态升级。

以下用于整体烧写

sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f

• 对于xavier，进行签名

cd $L4T_DIR

./l4t_sign_image.sh --file kernel/Image --chip 0x19

5 编译DTS

首先需要patch代码。

5.1 Nano

cp $RELEASE_PACK_DIR/Nano/JetPack_<ver>_Linux_JETSON_NANO_DEVKIT/dts\ dtb/common/t210/* -r $NANO_DTS_PATH/

For <camera model>

cp $RELEASE_PACK_DIR/Nano/JetPack_<ver>_Linux_JETSON_NANO_DEVKIT/dts\ dtb/<camera model>/tegra210-porg-plugin-manager.dtsi -r $NANO_DTS_PATH/porg/kernel-dts/porg-plugin-manager

5.2 TX2

cp $RELEASE_PACK_DIR/TX2/JetPack_<ver>_Linux_JETSON_TX2/dts\ dtb/common/t18x/* -r $TX2_DTS_PATH/

For <camera model>

cp $RELEASE_PACK_DIR/TX2/JetPack_<ver>_Linux_JETSON_TX2/dts\ dtb/<camera model>/tegra186-quill-p3310-1000-a00-00-base.dts $TX2_DTS_PATH/quill/kernel-dts/

5.3 AGX Xavier

cp $RELEASE_PACK_DIR/AGX-Xaviar/JetPack_<ver>_Linux_JETSON_AGX_XAVIER/dts\ dtb/common/t19x/* -r $XAVIER_DTS_PATH/

5.4 Xavier NX

cp $RELEASE_PACK_DIR/Xavier-NX/JetPack_<ver>_Linux_JETSON_XAVIER_NX_DEVKIT/dts\ dtb/common/t19x/* -r $XAVIER_DTS_PATH/

For <camera model>

cp $RELEASE_PACK_DIR/Xavier-NX/JetPack_<ver>_Linux_JETSON_XAVIER_NX_DEVKIT/dts\ dtb/<camera model>/tegra194-p3509-0000-a00.dtsi $XAVIER_DTS_PATH/jakku/kernel-dts/common/

5.5 编译

cd $L4T_DIR/sources/kernel/kernel-4.9/

make ARCH=arm64 O=$TEGRA_KERNEL_OUT dtbs

编译完成的dtb文件路径如下所示，可手动升级或整体升级。
