1.首先安装ubuntu18.04 安装如下软件包
sudo apt-get install subversion g++ zlib1g-dev build-essential git python python3 libncurses5-dev gawk gettext unzip file libssl-dev wget libelf-dev ecj fastjar java-propose-classpath asciidoc bzip2 libz-dev libtool2. 从如下仓库下载openwrt
git clone https://github.com/nxp-qoriq/openwrt.gi
cd openwrt
git checkout layerscape-20.09 -b layerscape-20.09
./scripts/feeds update -a
./scripts/feeds install -a3 联系FAE获取如下patch,并应用patch
cp 0001-nand-boot-support-solve-kernel-compile-issue-support.patch /home/openwrt
cp 0002-update-kernel-cfg-fix-netfilter-compile-error.patch /home/openwrt
git am signoff < 0001-nand-boot-support-solve-kernel-compile-issue-support.patch
git am signoff < 0002-update-kernel-cfg-fix-netfilter-compile-error.patch4. copy如下patch到指定目录
cp 011-algin_with_imx-5.4.70-2.3_kernel.patch /home/openwrt/linux/imx6ull/patches-5.4/
cp 012-remove-unsued-node-nand-dts.patch /home/openwrt/linux/imx6ull/patches-5.4/
cp 013-fix-MLC-NAND-not-supported.patch /home/openwrt/linux/imx6ull/patches-5.4/5. make menuconfig #配置 imx6ull nand 模式，参考nxp提供的配置文档。
6 make download #下载所有软件包
7 make 或者 make -j1 V=s #执行编译
8 编译过程中会有报错，作如下修改

endef9 参考 https://www.lijiandong.com.cn/?p=312 修改ddr部分代码。
10. 重新单独编译uboot/kernel，命令如下：
make package/boot/uboot-imx6ull/compile
make package/kernel/linux/compile11 采用uuu 烧写，完整系统启动log如下。
