Setup microSD card

We need to access the External Drive to be utilized by the target device. Run lsblk to help figure out what linux device has been reserved for your External Drive.

Code Block
titleExample: for DISK=/dev/sdX
lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk
├─sda1   8:1    0   512M  0 part /boot/efi
└─sda2   8:2    0 465.3G  0 part /                <- Development Machine Root Partition
sdb      8:16   1   962M  0 disk                  <- microSD/USB Storage Device
└─sdb1   8:17   1   961M  0 part                  <- microSD/USB Storage Partition
Code Block
titleThus you would use:
export DISK=/dev/sdb
Code Block
titleExample: for DISK=/dev/mmcblkX
lsblk
NAME      MAJ:MIN   RM   SIZE RO TYPE MOUNTPOINT
sda         8:0      0 465.8G  0 disk
├─sda1      8:1      0   512M  0 part /boot/efi
└─sda2      8:2      0 465.3G  0 part /                <- Development Machine Root Partition
mmcblk0     179:0    0   962M  0 disk                  <- microSD/USB Storage Device
└─mmcblk0p1 179:1    0   961M  0 part                  <- microSD/USB Storage Partition
Code Block
titleThus you would use:
export DISK=/dev/mmcblk0

Erase partition table/labels on microSD card:

Code Block
sudo dd if=/dev/zero of=${DISK} bs=1M count=50

Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.

Code Block
titleCheck the version of sfdisk installed on your pc
sudo sfdisk --version
Code Block
titleExample Output
sfdisk from util-linux 2.27.1
Code Block
titlesfdisk >= 2.26.x
sudo sfdisk ${DISK} <<-__EOF__
1M,48M,0xE,*
,,,-
__EOF__
Code Block
titlesfdisk <= 2.25.x
sudo sfdisk --unit M ${DISK} <<-__EOF__
1,48,0xE,*
,,,-
__EOF__

Format Partition:

Code Block
for: DISK=/dev/mmcblkX
sudo mkfs.vfat -F 16 -n BOOT ${DISK}p1
sudo mkfs.ext4 -L rootfs ${DISK}p2
 
for: DISK=/dev/sdX
sudo mkfs.vfat -F 16 -n BOOT ${DISK}1
sudo mkfs.ext4 -L rootfs ${DISK}2

Mount Partition:
On most systems these partitions may be auto-mounted...

Code Block
sudo mkdir -p /media/boot/
sudo mkdir -p /media/rootfs/
 
for: DISK=/dev/mmcblkX
sudo mount ${DISK}p1 /media/boot/
sudo mount ${DISK}p2 /media/rootfs/
 
for: DISK=/dev/sdX
sudo mount ${DISK}1 /media/boot/
sudo mount ${DISK}2 /media/rootfs/

Install Bootloader

Code Block
title~/uEnv.txt
loadaddr=0x02080000
fdtaddr=0x02000000
rdaddr=0x04000000
 
fdtfile=zynq-zc702.dtb
mmcroot=/dev/mmcblk0p2 ro
mmcrootfstype=ext4
 
loadximage=load mmc 0:1 ${loadaddr} /zImage
loadxfdt=load mmc 0:1 ${fdtaddr} /dtbs/${fdtfile}
loadxrd=load mmc 0:1 ${rdaddr} /boot/initrd.img-${uname_r}; setenv rdsize ${filesize}
loadall=run loadximage; run loadxfdt;
 
mmcargs=setenv bootargs console=ttyPS0,115200 ${optargs} root=${mmcroot} rootfstype=${mmcrootfstype} ${cmdline}
 
uenvcmd=run loadall; run mmcargs; bootz ${loadaddr} - ${fdtaddr};

Copy boot.bin/uEnv.txt to the boot partition

Code Block
title~/
sudo cp -v ./zc702/boot.bin /media/boot/
sudo cp -v ./uEnv.txt /media/boot/

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.

Code Block
-----------------------------
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.

Code Block
export kernel_version=5.X.Y-Z

Copy Root File System

Code Block
titleuser@localhost:~$
sudo tar xfvp ./*-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/

Copy Kernel Image

Kernel Image:

Code Block
titleuser@localhost:~$
sudo cp -v ./armv7-multiplatform/deploy/${kernel_version}.zImage /media/boot/zImage

Copy Kernel Device Tree Binaries

Code Block
titleuser@localhost:~$
sudo mkdir -p /media/boot/dtbs/
sudo tar xfvo ./armv7-multiplatform/deploy/${kernel_version}-dtbs.tar.gz -C /media/boot/dtbs/

Copy Kernel Modules

Code Block
titleuser@localhost:~$
sudo tar xfv ./armv7-multiplatform/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/

File Systems Table (/etc/fstab)

Code Block
sudo sh -c "echo '/dev/mmcblk0p2  /  auto  errors=remount-ro  0  1' >> /media/rootfs/etc/fstab"
sudo sh -c "echo '/dev/mmcblk0p1  /boot/uboot  auto  defaults  0  2' >> /media/rootfs/etc/fstab"

Remove microSD/SD card

Code Block
sync
sudo umount /media/boot
sudo umount /media/rootfs
