 ## **编译方法**
 #### 1. 从仓库获取最新代码  
-		<code>git clone https://git.komect.net:SDX/vBRAS.git</code>  
-		或  
-		<code>git pull</code>  
+<code>git clone https://git.komect.net:SDX/vBRAS.git</code>  
+或  
+<code>git pull</code>  
 
 #### 2. 安装必要软件(UBuntu)  
-		<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</code>  
-

+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</code>  
+
 #### 3. 安装 linux 内核源代码  
-	    <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</code>  
+<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</code>  
 
 #### 4. 设置环境变量  
-		在 ~/.bashrc 文件末尾加上以下几行配置  
-		<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</code>
+在 ~/.bashrc 文件末尾加上以下几行配置  
+<code>export HUACHENG_LINUX_KERNEL=/opt/fsl-kernel/x86/linux-4.9.140

+source ~/.bashrc</code>
 
 #### 5. 编译内核  
-		+ x64_86  
-        ```
-		cd /opt/fsl-kernel/x86/linux-4.9.140 && make -j
-		```
-	    + arm64  
-        <code>cd /opt/fsl-kernel/arm64/linux-4.9.140 && unset LDFLAS</code>		
-		修改 Makefile 文件第 257、258 两行	
-	    <code>ARCH ?= $(SUBARCH)
-		  CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)</code>		
-	    为	  
-	    <code>ARCH ?= arm64
-	    CROSS_COMPILE ?= aarch64-fsl-linux-</code>		
-		
-		然后运行 make 命令进行编译
++ x64_86  
+```
+cd /opt/fsl-kernel/x86/linux-4.9.140 && make -j
+```
++ arm64  
+<code>cd /opt/fsl-kernel/arm64/linux-4.9.140 && unset LDFLAS</code>		
+修改 Makefile 文件第 257、258 两行	
+<code>ARCH ?= $(SUBARCH)
+	CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)</code>		
+为	  
+<code>ARCH ?= arm64
+CROSS_COMPILE ?= aarch64-fsl-linux-</code>		
+
+然后运行 make 命令进行编译
