STM32MP1 запуск Ubuntu 22.04GPU и графический сервер Wayland…25.05.2022 16:46

Привет, Хабр!

Совсем недавно, компания Canonical, выпустила Ubuntu 22.04, «потыкав» ее на виртуалке, решил накатить апдейт на домашний ноут, пока накатывались обновления, перебирал девкиты на полке, нашел запыленную STM32MP157c-DK2 отладучную платку от старого проекта, ну и подумал — почему бы и не попробовать запустить 22-ю убунту на этом CPU
Благо Canonical публикует в открытый доступ релизы базового rootfs для ARM процессоров.

В интернете полно статей как собрать Yocto или Buildroot под данный процессор, но ни одной как собрать свой собственный дистрибутив, по крайней мере, я не встречал.

STMicroelectronics может похвастаться огромным выбором 8-bit и 32-bit микроконтроллеров (MCU), но так же в их арсенале есть CPU STM32MP1

Существует три семейства процессоров серии STM32MP1: STM32MP151, STM32MP153 и STM32MP157. Их основные характеристики приведены в таблице.

STM32MP1STM32MP1

STM32MP1 ядра Cortex-A7 работают на частоте 650 МГц и сопровождаются 32-Кбайтным кешем инструкций L1, 32-Кбайтным кешем первого уровня и 256-Кбайтным кешем второго уровня. Также A7 поставляются с расширениями устройства Arm Neon SIMD, предназначенных для ускорения работы мультимедиа и алгоритмов обработки сигналов.

Для поддержания обработки в режиме реального времени с низким энергопотреблением ядро Cortex-M4 работает на частоте 209 МГц с модулем обработки чисел с плавающей точкой (FPU), полным набором DSP команд и с модулем защиты памяти (MPU), предназначенным для повышения безопасности использования устройства.

Линейка STM32MP1 имеет встроенный дополнительный 3D графический процессор GPU совместимый с OpenGL для расширенной разработки HMI, работающей на частоте 533 МГц. GPU поддерживает интерфейсы DDR и LPDDR с тактовой частотой 533 МГц, 256 КБ системной оперативной памяти, а также 384 КБ ОЗУ MCU и 64 КБ оперативной памяти, что облегчает Cortex-M4 обработку в режиме реального времени и работу в режиме пониженного энергопотребления.

Для проведения безопасных операций, STM32MP1 предлагает надежный набор инструментов безопасности, включая технологию Arm TrustZone, которая обеспечивает изоляцию аппаратного обеспечения для повышения надежности функционирования ПО в целом, в масштабе всей системы. Кромее того, STM32MP1 поддерживает аппаратную криптографическую опцию, имеет защищенные ОЗУ и ПЗУ, а также защиту от несанкционированного доступа и защищенные часы реального времени. Линейка предлагает 16- и 32-разрядные элементы управления и таймеры, а для аналоговых входов — два полных 16-разрядных АЦП с поддержкой до 22 каналов обработки.

В дополнение ко всему, STM32MP1 предлагает до 20 коммуникационных интерфейсов, поддерживающих широкую номерклатуру камер, дисплеев, сети Ethernet, порты USB, HDMI и UART. Для большей функциональной гибкости, обслуживание работы большинства периферийных устройств может быть распределена между Cortex-A7 или Cortex-M4.

Собственно начнем.

Билдить будем на ноуте с установленной Ubuntu, можно на виртуалке, уделенной машине, без разницы — нам нужна только консолька.

Собирать будем по такую плату STM32MP157c-DK2

Разабьем сборку на этапы:

  1. Собираем U-boot .

  2. Собираем OP-TEE — да, грузить ядро и Ubuntu 22.04 будем в защищенном режиме, в инете полно статей как собрать бутлоадер на этот проц, но нет как собрать arm-trust.

  3. Собираем ядро Linux .

  4. Кастомизируем базовый rootfs Ubuntu 22.04.

  5. Собираем все это в одну кучу и создаем готовый .img для заливки на SD карту.

Первым делом качаем ARM кросс компилятор GCC и распаковываем, им будем собирать всю нашу систему.

mkdir stm32mp && cd stm32mp
wget -c https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/10.3.0/x86_64-gcc-10.3.0-nolibc-arm-linux-gnueabi.tar.gz
tar xf x86_64-gcc-10.3.0-nolibc-arm-linux-gnueabi.tar.gz
export CC=`pwd`/gcc-10.3.0-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-

Проверяем версию: 

${CC}gcc --version

Выхлоп

Устанавливаем зависимости: 

sudo apt install flex bison ncurses-base build-essential qemu-user-static device-tree-compiler

U-Boot

Качаем U-boot с репозитория ST и собираем trusted u-boot

git clone -b v2020.10-stm32mp https://github.com/STMicroelectronics/u-boot
cd u-boot
make ARCH=arm CROSS_COMPILE=${CC} stm32mp15_trusted_defconfig
make ARCH=arm CROSS_COMPILE=${CC} DEVICE_TREE=stm32mp157c-dk2 u-boot.stm32 all

9a07b875f03a33a9457b5f0ffbd0126c.png


Нам понадобятся два файла u-boot.dtb и u-boot-nodtb.bin для подписи и сборки OP-TEE

Качаем OP-TEE с git ST
Внимательно к переменоой BL33_CFG и BL33 мы указываем каталог где лежит собраный U-boot и файлы u-boot.dtb и u-boot-nodtb.bin 

# Возвращаемся назад в рабочий каталог stm32mp
cd ..
git clone -b v2.4-stm32mp https://github.com/STMicroelectronics/arm-trusted-firmware
cd arm-trusted-firmware

Kernel Linux

Собирать ядро, будем с официального репозитоия ST, читам релизноты и смотрим что там добавили нового и пофиксили. На данный момент крайняя версия 5.10.61 

# Возвращаемся назад в рабочий каталог stm32mp
cd ..
git clone -b v5.10-stm32mp https://github.com/STMicroelectronics/linux
cd linux
make ARCH=arm CROSS_COMPILE=${CC} multi_v7_defconfig fragment-01-multiv7_cleanup.config fragment-02-multiv7_addons.config
make ARCH=arm CROSS_COMPILE=${CC} menuconfig

Конфигурируем ядро по своему вкусу и задач, multi_v7_defconfig уже содержит все необходиое, в конфиг фрагментах, находяться дравера для STM32MP1 CPU и выключена поддержка жругих архитектур, что входят в базовый общий конфиг armv7 процессоров.
К статье прикреплю свой конфиг, с которым собирал ядро.

Собираем ядро и модули к нему

make ARCH=arm CROSS_COMPILE=${CC} zImage modules -j16

Собираем dts

make ARCH=arm CROSS_COMPILE=${CC} dtbs

Создаем временный каталог и копитуем туда артефакты сборки 

mkdir -p ../deploy
cp -v arch/arm/boot/zImage ../deploy
mkdir -p ../deploy/modules
make ARCH=arm CROSS_COMPILE=${CC} modules_install INSTALL_MOD_PATH="../deploy/modules"

e78970eff45b2c81a90c68ec9fbc9e5c.png

Копируем dtsb файлы 

mkdir -p ../deploy/dtsb
make ARCH=arm CROSS_COMPILE=${CC} dtbs_install INSTALL_DTBS_PATH=../deploy/dtsb

Создаем переменную с версией ядра

export kernel_ver=$(cat "include/generated/utsrelease.h" | awk '{print $3}' | sed 's/\"//g' )
echo ${kernel_ver}
cd ..

2c7a025a108c6a2a8a043525d51ad13d.png

Подготовка образа SD карты, создаем образ и разбиваем на разделы и делаем его загружаемым 

export IMAGE_FILENAME="sdcard-stm32mp157.img"
dd if=/dev/zero of=${DIR}/deploy/${IMAGE_FILENAME} bs=4096M count=2

sgdisk --resize-table=128 -a 1 \
            -n 1:34:545    -c 1:fsbl1   \
            -n 2:546:1057  -c 2:fsbl2   \
            -n 3:1058:5153 -c 3:fip    \
            -n 4:5154:     -c 4:rootfs  \
            -p ./deploy/${IMAGE_FILENAME}
            
sgdisk -A 4:set:2 ./deploy/${IMAGE_FILENAME}

Для манипуляции с файловой системой в .img, можем воспользоваться утилитой loop

 LOOP_DEVICE=$(sudo losetup --partscan --show --find ./deploy/${IMAGE_FILENAME})
 ls -l ${LOOP_DEVICE}*

d3975f5311d8d141a2b7ef09af7cd057.png

Копируем наш подписаный u-boot и файл с конфигурацией RAM

sudo dd if=./arm-trusted-firmware/build/stm32mp1/release/tf-a-stm32mp157c-dk2.stm32 of=${LOOP_DEVICE}p1
sudo dd if=./arm-trusted-firmware/build/stm32mp1/release/tf-a-stm32mp157c-dk2.stm32 of=${LOOP_DEVICE}p2
sudo dd if=./arm-trusted-firmware/build/stm32mp1/release/fip.bin of=${LOOP_DEVICE}p3

Форматируем раздел с нашим будущим rootfs. Создаем каталог для монтирования нашей файловой системы и монтируем 

sudo mkfs.ext4 -L rootfs ${LOOP_DEVICE}p4
sudo mkdir -p deploy/rootfs
MOUNT_PATH=deploy/rootfs
sudo mount ${LOOP_DEVICE}p4 ${MOUNT_PATH}

скачиваем Ubuntu 22.04 базовый образ и распаковываем примонтированый каталог 

wget https://cdimage.ubuntu.com/ubuntu-base/releases/22.04/release/ubuntu-base-22.04-base-armhf.tar.gz
sudo tar xvfp ubuntu-base-22.04-base-armhf.tar.gz -C ${MOUNT_PATH}

214643aae0891b11dd8786613174b7a5.png

Создаем файл extlinux.conf

sudo mkdir -p ${MOUNT_PATH}/boot/extlinux/
sudo sh -c "echo 'label Linux ${kernel_ver}' > ${MOUNT_PATH}/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    kernel /boot/vmlinuz-${kernel_ver}' >> ${MOUNT_PATH}/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    append console=ttySTM0,115200 console=tty1,115200 root=/dev/mmcblk0p4 ro rootwait ' >> ${MOUNT_PATH}/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    fdtdir /boot/dtbs/${kernel_ver}/' >> ${MOUNT_PATH}/boot/extlinux/extlinux.conf"

Копируем наше ядро, dtsb, модули ядра

sudo cp -v ./deploy/${kernel_ver}.zImage ${MOUNT_PATH}/boot/vmlinuz-${kernel_ver}

sudo mkdir -p ${MOUNT_PATH}/boot/dtbs/${kernel_ver}/
sudo cp -r ./deploy/dtsb/* ${MOUNT_PATH}/boot/dtbs/${kernel_ver}/

    sudo umount -l ${2}proc
    sudo umount -l ${2}sys
    sudo umount -l ${2}dev/pts
    sudo umount -l ${2}dev

}

if [ "$1" == "-m" ] && [ -n "$2" ] ;
then
    mnt $1 $2
elif [ "$1" == "-u" ] && [ -n "$2" ];
then
    umnt $1 $2
else
    echo ""
    echo "Either 1'st, 2'nd or both parameters were missing"
    echo ""
    echo "1'st parameter can be one of these: -m(mount) OR -u(umount)"
    echo "2'nd parameter is the full path of rootfs directory(with trailing '/')"
    echo ""
    echo "For example: ch-mount -m /media/sdcard/"
    echo ""
    echo 1st parameter : ${1}
    echo 2nd parameter : ${2}
fi

Устанавливаем нужные нам пакеты

echo stm32mp1 > /etc/hostname
echo 127.0.0.1	localhost > /etc/hosts
echo 127.0.1.1	stm32mp1 >> /etc/hosts

apt update 
apt upgrade 

# устанавливаем нужные нам пакеты
apt install systemd sudo ifupdown net-tools ethtool udev wireless-tools iputils-ping resolvconf wget apt-utils wpasupplicant nano

# создаем пользователя и устанавливаем пароль
useradd -s '/bin/bash' -m -G adm,sudo ubuntu
passwd ubuntu

# пароль рута
passwd root


exit

После того как установили нудные вам пакеты для, не забываем выйти

P.S. Вы можете сколько угодно раз монтировать этот готовый образ и доустанавливать новы пакеты.

Размонтируем все каталоги и очистим loop

sync
sudo ch-mount.sh -u ${MOUNT_PATH}/
sudo umount ${MOUNT_PATH}
sudo losetup -D/de

Записываем с помощью balenaEtcher наш образ на SD карту
