2. #### 安装必要软件(UBuntu)
``` bash
sudo ./fsl-qoriq-glibc-x86_64-fsl-toolchain-aarch64-toolchain-2.4.1.sh
<code>sudo ./fsl-qoriq-glibc-x86_64-fsl-toolchain-aarch64-toolchain-2.4.1.sh
sudo apt-get -y install git u-boot-tools device-tree-compiler autoconf curl flex
sudo apt-get -y install automake dh-autoreconf libssl-dev openssl libpcap-dev bc
sudo apt-get -y install python-pip qemu-utils libncurses5-dev python-crypto bison
```
sudo apt-get -y install python-pip qemu-utils libncurses5-dev python-crypto bison</code>
3. #### 安装 linux 内核源代码
``` bash
sudo mkdir -p /opt/fsl-kernel /opt/fsl-kernel/arm64 /opt/fsl-kernel/x86
<code>sudo mkdir -p /opt/fsl-kernel /opt/fsl-kernel/arm64 /opt/fsl-kernel/x86
sudo chmod 777 /opt/fsl-kernel -R
cp ./vBRAS/Platform/kernel/linux-4.9.140.tar.gz /opt/fsl-kernel
cd /opt/fsl-kernel
tar -xvaf ./linux-4.9.140.tar.gz ./
cp ./linux-4.9.140 ./x86
cp ./linux-4.9.140 ./arm64
```
cp ./linux-4.9.140 ./arm64</code>
4. #### 设置环境变量
在 ~/.bashrc 文件末尾加上以下几行配置
``` bash
export HUACHENG_LINUX_KERNEL=/opt/fsl-kernel/x86/linux-4.9.140
<code>export HUACHENG_LINUX_KERNEL=/opt/fsl-kernel/x86/linux-4.9.140
export HUACHENG_ARM64_KERNEL=/opt/fsl-kernel/arm64/linux-4.9.140
export SDKTARGETSYSROOT=/opt/fsl-qoriq/2.4.1/sysroots/aarch64-fsl-linux
export PATH=/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/sbin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/sbin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/../x86_64-fslsdk-linux/bin:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux:/opt/fsl-qoriq/2.4.1/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux-musl:$PATH
source ~/.bashrc
```
source ~/.bashrc</code>
5. #### 编译内核
- x64_86
``` bash
cd /opt/fsl-kernel/x86/linux-4.9.140 && make -j
```
<code>cd /opt/fsl-kernel/x86/linux-4.9.140 && make -j</code>
- arm64
``` bash
cd /opt/fsl-kernel/arm64/linux-4.9.140 && unset LDFLAS
```
<code>cd /opt/fsl-kernel/arm64/linux-4.9.140 && unset LDFLAS</code>
修改 Makefile 文件第 257、258 两行
``` bash
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
```
<code>ARCH ?= $(SUBARCH)
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)</code>
为
``` bash
ARCH ?= arm64
CROSS_COMPILE ?= aarch64-fsl-linux-
```
<code>ARCH ?= arm64
CROSS_COMPILE ?= aarch64-fsl-linux-</code>
然后运行 make 命令进行编译
