2.2.配置與編譯Optee-OS
本文引用地址：http://www.butianyuan.cn/article/202502/467457.htm現(xiàn)在進(jìn)行OP-TEE的配置編譯，首先需要在設(shè)備樹(shù)中添加串口 UART 以及 PWR 相關(guān)的配置：
串口部分配置：
在之前 STM32CubeMX 配置串口的過(guò)程中，UART 的配置是沒(méi)辦法在 OP-TEE 中使能的，也就是說(shuō) OP-TEE 的設(shè)備樹(shù)中沒(méi)有任何關(guān)于串口的配置，包括 UART 節(jié)點(diǎn)以及引腳，這些都需 要我們手動(dòng)添加上去：

在上一章節(jié)中提到stm32mp257d-bringup-mx-resmem.dtsi 和 stm32mp257d-bringup-mx-rif.dtsi 直接使用 SourceCode 壓縮包 Optee-os 目錄中的文件，如果還未拷貝，需要將其通過(guò)軟鏈接或者拷貝的方式放到stm32mp25x-BringUp-bsp/myir-st-optee/myir-st-optee/core/arch/arm/dts/目錄下。
編譯 Optee
myir@myir-vm: cd /home/myir/stm32mp25x-BringUp-bsp/myir-st-optee/myir-st-optee

注：已將上述Optee單獨(dú)編譯的命令存放在/home/myir/stm32mp25x-BringUp-bsp/myir-st-optee/myir-st-optee/build.sh
可以看到已經(jīng)生成了bin文件
2.3.配置和編譯Uboot
已同樣的方式進(jìn)行手動(dòng)添加uboot的設(shè)備樹(shù)的一些配置，使用編輯工具打開(kāi)uboot下的(BringupCA35DeviceTreeBringupu-bootstm32mp257d-bringup-mx.dts)
/* USER CODE BEGIN root */

/* USER CODE END root */

pinctrl-1 = <&sdmmc2_opendrain_pins_mx>;

使用編輯工具打開(kāi)uboot下的(BringupCA35DeviceTreeBringupu-bootstm32mp257d-bringup-mx-u-boot.dtsi)
