新建工程
输入STM32MP257DAK3
勾选第二个选项 - A35 Master with Cotex M33 TrustZone actived
保存工程
配置DDR_CTRL_PHY如下图所示，点击生成代码
配置串口USART2，用作输出串口调试信息
准备external-dt-6.0-r0
参考external-dt-6.0-r0目录下README.HOW_TO.txt.stm32mp2，非常重要！！！
！！！注意：如果是在当前的shell环境下面，则不需要重新声明TF-A的环境变量

cd external-dt-6.0-r0/
vi test.sh
#在test.sh增加以下内容，参考README.HOW_TO.txt.stm32mp2的2.1，打补丁+git管理
tar xf external-dt-6.0-r0.tar.xz
cd external-dt-6.0
test -d .git || git init . && git add . && git commit -m "new dt" && git gc
git checkout -b WORKING
#end of test.sh
/bin/bash test.sh建立软连接
