ARM Cross Compiler: GCC

This is a pre-built (64bit) version of GCC that runs on generic linux, sorry (32bit) x86 users, it’s time to upgrade… Download/Extract:

#user@localhost:~$
wget -c https://releases.linaro.org/components/toolchain/binaries/6.5-2018.12/arm-linux-gnueabihf/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz
export CC=`pwd`/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

Test Cross Compiler:

#user@localhost:~$
${CC}gcc --version

#Test Output:
arm-linux-gnueabihf-gcc (Linaro GCC 6.5-2018.12) 6.5.0

Bootloader: U-Boot

Das U-Boot – the Universal Boot Loader: http://www.denx.de/wiki/U-Boot
Depending on your Linux Distrubution, you will also need a host gcc and other tools, so with Debian/Ubuntu start with installing the build-essential meta package.
Download:

Setup image for flash to microSD card

Create image:

sudo dd if=/dev/zero of=~/sdcard.img bs=4096M count=2
export DISK=~/sdcard.img

check output dd:

# check output:
# 0+2 records in
# 0+2 records out
# 4294959104 bytes (4,3 GB, 4,0 GiB) copied, 13,5095 s, 318 MB/s

Create Partition Layout:

sudo 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:ssbl    \
        -n 4:5154:     -c 4:rootfs  \
        -p ${DISK}

check output sgdisk:

#

# Sector size (logical): 512 bytes
# Disk identifier (GUID): 6473AC10-6A3A-4A4B-B3BF-59BD7982185D
# Partition table holds up to 128 entries
# Main partition table begins at sector 2 and ends at sector 33
# First usable sector is 34, last usable sector is 8388558
# Partitions will be aligned on 1-sector boundaries
# Total free space is 0 sectors (0 bytes)

Set legacy BIOS partition:

sudo sgdisk -A 4:set:2 ${DISK}

Create loop device

sudo losetup --partscan --show --find ${DISK}

Check mounted partition:

ls -l /dev/loop0*

#user@localhost:~$ ls -l /dev/loop0*
brw-rw---- 1 root disk   7,  0 лис  7 13:31 /dev/loop0
brw-rw---- 1 root disk 259,  7 лис  7 13:31 /dev/loop0p1

brw-rw---- 1 root disk 259, 10 лис  7 13:31 /dev/loop0p4

Install U-Boot bootloader:

#user@localhost:~$
sudo dd if=./u-boot/u-boot-spl.stm32 of=/dev/loop0p1
sudo dd if=./u-boot/u-boot-spl.stm32 of=/dev/loop0p2
sudo dd if=./u-boot/u-boot.img of=/dev/loop0p3

Format RootFS Partition:

sudo mkfs.ext4 -L rootfs /dev/loop0p4

Mount rootfs file system

sudo mkdir -p /mnt/rootfs
sudo mount /dev/loop0p4 /mnt/rootfs/

Install Kernel and Root File System

To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.

-----------------------------
Script Complete
eewiki.net: [user@localhost:~$ export kernel_version=5.X.Y-Z]
-----------------------------

Copy and paste that “export kernel_version=5.X.Y-Z” exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.

export kernel_version=5.X.Y-Z

Copy Root File System

#Debian; Root File System: user@localhost:~$
sudo tar xfvp ./debian-*-*-armhf-*/armhf-rootfs-*.tar -C /mnt/rootfs/
sync

#Ubuntu; Root File System: user@localhost:~$
sudo tar xfvp ./ubuntu-*-*-armhf-*/armhf-rootfs-*.tar -C /mnt/rootfs/
sync

Setup extlinux.conf

#user@localhost:~$
sudo mkdir -p /mnt/rootfs/boot/extlinux/
sudo sh -c "echo 'label Linux ${kernel_version}' > /mnt/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    kernel /boot/vmlinuz-${kernel_version}' >> /mnt/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    append console=ttySTM0,115200 console=tty1,115200 console=tty0,115200 fbcon=rotate:3 root=/dev/mmcblk0p4 ro rootfstype=ext4 rootwait' >> /mnt/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    fdtdir /boot/dtbs/${kernel_version}/' >> /mnt/rootfs/boot/extlinux/extlinux.conf"

Copy Kernel Image

#user@localhost:~$
sudo cp -v ./armv7-lpae-multiplatform/deploy/${kernel_version}.zImage /mnt/rootfs/boot/vmlinuz-${kernel_version}

Copy Kernel Device Tree Binaries

#user@localhost:~$
sudo mkdir -p /mnt/rootfs/boot/dtbs/${kernel_version}/
sudo tar xfv ./armv7-lpae-multiplatform/deploy/${kernel_version}-dtbs.tar.gz -C /mnt/rootfs/boot/dtbs/${kernel_version}/

Copy Kernel Modules

#user@localhost:~$
sudo tar xfv ./armv7-lpae-multiplatform/deploy/${kernel_version}-modules.tar.gz -C /mnt/rootfs/

File Systems Table (/etc/fstab)

#user@localhost:~/$
sudo sh -c "echo '/dev/mmcblk0p4  /  auto  errors=remount-ro  0  1' >> /mnt/rootfs/etc/fstab"

Finish:

sync
sudo umount /mnt/rootfs
sudo losetup -D

After successfully completing these steps, you will get .img image for writing to SD card

How to flash .img to SD card

For safe and easy writing to SD card download balenaEtcher

Steps:

Insert SD card to card reader
Openn balenaEtcher
Select sdcard.img
Select connected SD card
Push button FLash
Done

After flash remove sd card from PC and insert to STM32MP157 board

Finished image for flash SD card for STM32MP157-DK2

If you do not want to go through all the steps, you can download the finished SD card image, just write it to the SD card
