米尔STM32MP25x开发板Bring Up培训课程

1.概述本文援用地点：本文将以 MYIR 的 MYC-LD25X 中心模块及MYD-LD25X开辟平台为例，讲授怎样应用 STM32CubeMX 来实现Developer package最小体系跟外设资本的设置。2.修正装备树（接上一期）检查天生的Bring up工程空文件的装备树，CA35的装备树文件夹，其余的是M33核的工程材料。咱们能够看到天生的装备树文件如下myir@myir-vm:/mnt/hgfs/ShareWorkspace/stm32mp25x-bringup/Bringup/CA35/DeviceTree/Bringup$ tree -l.├── kernel│   ├── stm32mp257d-bringup-mx.dts│   └── stm32mp257d-bringup-mx-resmem.dtsi├── optee-os│   ├── stm32mp257d-bringup-mx.dts│   ├── stm32mp257d-bringup-mx-rcc.dtsi│   ├── stm32mp257d-bringup-mx-resmem.dtsi│   └── stm32mp257d-bringup-mx-rif.dtsi├── tf-a│   ├── stm32mp257d-bringup-mx.dts│   ├── stm32mp257d-bringup-mx-fw-config.dts│   ├── stm32mp257d-bringup-mx-rcc.dtsi│   └── stm32mp25-mx.dtsi└── u-boot    ├── stm32mp257d-bringup-mx.dts    ├── stm32mp257d-bringup-mx-resmem.dtsi    └── stm32mp257d-bringup-mx-u-boot.dtsi4 directories, 13 files以上的装备树曾经设置了年夜局部内容的工程，然而工程是还无奈全体启动，咱们须要先把装备树同步到响应的BSP代码中。stm32mp25x-BringUp-bsp.tar.gz已拷贝并解压到虚构机：/home/myir。       注：windows跟ubuntu之间目次共享myir@myir-vm:~/stm32mp25x-BringUp-bsp$ tree -L 2.├── Bringup│   ├── Bringup.ioc│   ├── CA35│   ├── CM33│   ├── Common│   └── Drivers├── build├── FIP_artifacts│   ├── arm-trusted-firmware│   ├── fip│   ├── flash-all.sh│   ├── FlashLayout_emmc_stm32mp25x-bringup-mx.tsv│   ├── flash.sh│   ├── optee│   └── u-boot├── myir-st-optee│   ├── fiptool-stm32mp│   ├── Makefile.sdk│   ├── myir-st-external-dt│   ├── myir-st-optee│   └── README├── myir-st-tfa│   ├── fiptool-stm32mp│   ├── Makefile.sdk│   └── tf-a-myir├── myir-st-uboot│   ├── fiptool-stm32mp│   ├── Makefile.sdk│   └── u-boot-myir└── stm32mp-ddr-phy-A2022.11-r0    ├── README.HOW_TO.txt    └── stm32mp-ddr-phy-A2022.1119 directories, 13 files在“虚构机设置”选项中设置实现后， 启动虚构机履行如下下令停止挂载： myir@myir-vm# sudo vmhgfs-fuse .host:/ /mnt/hgfs -o allow_othersudo 暗码为：123456      在虚构机的/mnt/hgfs目次下曾经胜利挂载上共享的目次，如未挂载上，能够从新启动下虚构机。/home/myir/目次为我这边虚构机的目次，现实目次以本人本机为准。tf-a装备树软链接：myir@myir-vm:/mnt/hgfs/ShareWorkspace#  ln -s /mnt/hgfs/ShareWorkspace/Bringup/CA35/DeviceTree/bringup/tf-a/* /home/myir/stm32mp25x-BringUp-bsp/myir-st-tfa/tf-a-myir/fdts/Optee-os装备树stm32mp257d-bringup-mx.dts跟stm32mp257d-bringup-mx-rcc.dtsi软链接：myir@myir-vm:/mnt/hgfs/ShareWorkspace# ln -s /mnt/hgfs/ShareWorkspace/Bringup/CA35/DeviceTree/bringup/optee-os/stm32mp257d-bringup-mx.dts /home/myir/stm32mp25x-BringUp-bsp/myir-st-optee/myir-st-optee/core/arch/arm/dts/
