要在刷写之前构建 ti-linux-kernel 代码、请遵循以下步骤：

通过链接 www.ti.com/.../PROCESSOR-SDK-AM65X 下载 PROCESSOR-SDK-LINUX-RT-AM65X --适用于 AM65x 的 Linux -RT Processor SDK for AM65x 各版本、并进行安装
```
chmod +x ./ti-processor-sdk-linux-[platform]-<version>-Linux-x86-Install.bin
./ti-processor-sdk-linux-[platform]-<version>-Linux-x86-Install.bin
```
请访问 https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM65X/08_02_00_01/exports/docs/linux/Overview_Getting_Started_Guide.html

准备 SD 卡

cd <path>/ti-processor-sdk-linux-rt-am65xx-evm-"$SDK_VERSION"/bin
sudo ./mksdboot.sh --sdk <path>/ti-processor-sdk-linux-rt-am65xx-evm-"$SDK_VERSION"/ --device /dev/sd<x>
sync

如果从 ti-linux-kernel 闪存代码、而不是可用的默认映像、请从 ti-linux-kernel 克隆并签出至所需的标签
```
git clone git.ti.com/.../ti-linux-kernel.git
//checkout to required tag
git checkout tags/{specify the tag}
```

如果从 ti-linux-kernel 编辑和构建代码、请转至下载的 Git 存储库路径、否则转至下载的 SDK 的路径

//Go to path of downloaded repository
cd Downloads/ti-linux-kernel

//if building from SDK
cd <path of SDK>/board-support/linux-rt...

构建 SDK 并将映像和 DTB 复制到 SD 卡

 //sdk path is the path of the downloaded sdk
export PATH=<sdk path>/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH
 
//Command to clean kernel
make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- distclean
 
//Build defconfig from kernel git repository 
//for version before 9.0
ti_config_fragments/defconfig_builder.sh -t ti_sdk_arm64_release || ti_config_fragments/defconfig_builder.sh
make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- ti_sdk_arm64_rt_release_defconfig

//for 9.0 or later versions
make ARCH=arm64 CROSS_COMPILE=$V8_CROSS defconfig ti_arm64_prune.config 
 
//Build Image
make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- Image
 
//Build device tree binaries
make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- dtbs
 
//Compiling kernel modules
make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- modules
 
//Copying kernal image and device tree binaries to rootfs partition of sd card
cd <kernel sources dir>
sudo cp arch/arm64/boot/Image /media/rootfs/boot
sudo cp arch/arm64/boot/dts/ti/*.dtb /media/rootfs/boot
sudo cp arch/arm64/boot/dts/ti/*.dtbo /media/rootfs/boot
 
//Installing kernel modules
sudo make ARCH=arm64 INSTALL_MOD_PATH=/media/rootfs modules_install

将 SD 卡插入电路板并启动
重新启动板
