2-1. STM32mp157 Developer Package - uBoot

<Spec>

• target Board : STM32mp157f-ev1, STM32mp157d-dk1
• Ubuntu : ubuntu-18.04.5-desktop-amd64
• stm32mpu Major ecosystem releases version : v3.0.0
• U-Boot : v2020.10
• TF-A : v2.4
• OP-TEE : v3.12.0

 

STM32MP1에서 제공되는 Developer Package를 이용해 개발 환경을 구축할 것이다.

uboot name을 customizing 하여 빌드 및 부팅되는지 확인한다.

└── u-boot-stm32mp157f-whatmam-ev1-trusted.dtb

 

아래와 같은 make 실행하여 .config 생성된 상태라면 make mrproper 꼭 해줘야 한다.

 

 - Makefile 사용

$ make stm32mp15_trusted_defconfig
$ make DEVICE_TREE=stm32mp157f-ev1 all

 > Makefile.sdk 사용 시 하지 않아도 된다.

 

5. optee build

└── tee-pager_v2-stm32mp157f-whatmam-ev1.bin

 

6. fip build

fip는 tf-a, uboot, optee 어디든 빌드가 가능하다.

빌드된 파일들이 모여있는 FIP_artifacts의 폴더를 지정하고 tf-a에 있는 Makefile.sdk을 사용하도록 하겠다.

$ cd ~/STM/Developer-Package/stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31/sources/arm-ostl-linux-gnueabi/tf-a-stm32mp-2.4.r1-r0/tf-a-stm32mp-2.4.r1
$ source ~/STM/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
$ export DEPLOYDIR=$PWD/../../FIP_artifacts/arm-trusted-firmware
$ export FIP_DEPLOYDIR_ROOT=$PWD/../../FIP_artifacts
$ make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157f-whatmam-ev1 ELF_DEBUG_ENABLE='1' fip

 

 - output files

$ tree -L 1 $FIP_DEPLOYDIR_ROOT/fip
├── fip-stm32mp157f-whatmam-ev1-optee.bin
└── fip-stm32mp157f-whatmam-ev1-trusted.bin

└── tf-a-stm32mp157f-whatmam-ev1-usb.stm32

 

7. FIP_artifacts 확인

$ cd $FIP_DEPLOYDIR_ROOT
$ find . -name "debug" -type d | xargs rm -rf
$ tree -L 3

└── u-boot
    ├── u-boot-nodtb-stm32mp15.bin
    └── u-boot-stm32mp157f-whatmam-ev1-trusted.dtb

 - 빌드 순서 요약 : tf-a, uboot, optee는 독립적으로 빌드 후 최종 fip빌드는 3중 아무곳에서 해도 됩니다.

 

8. Create SD Card

$ cd $FIP_DEPLOYDIR_ROOT/arm-trusted-firmware
$ sudo dd if=tf-a-stm32mp157f-whatmam-ev1-sdcard.stm32 of=/dev/sdb1 conv=fdatasync
$ sudo dd if=tf-a-stm32mp157f-whatmam-ev1-sdcard.stm32 of=/dev/sdb2 conv=fdatasync

$ cd $FIP_DEPLOYDIR_ROOT/fip
$ sudo dd if=/dev/zero of=/dev/sdb3 conv=fdatasync
$ sudo dd if=fip-stm32mp157f-whatmam-ev1-trusted.bin of=/dev/sdb3 conv=fdatasync
$ umount /media/whatmam/*

 sd Card의 Partitions 1,2에 tf-a-stm32mp157f-whatmam-ev1-sdcard.stm32

               Partitions 3에 fip-stm32mp157f-whatmam-ev1-trusted.bin
