Linux Kernel

This script will build the kernel, modules, device tree binaries and copy them to the deploy directory.
Download:

#user@localhost:~$
git clone https://github.com/RobertCNelson/armv7-multiplatform
cd armv7-multiplatform/

For v4.6.x (Stable):

#user@localhost:~/armv7-multiplatform$
git checkout origin/v4.6.x -b tmp

For v4.7.x (Prepatch):

#user@localhost:~/armv7-multiplatform$
git checkout origin/v4.7.x -b tmp

Build:

#user@localhost:~/armv7-multiplatform$
./build_kernel.sh

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.

#Example: 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
#Thus you would use:
export DISK=/dev/sdb
#Example: 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
#Thus you would use:
export DISK=/dev/mmcblk0

Erase partition table/labels on microSD card:

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.

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

Format Partition:

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…

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

#~/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:

#~/
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.

-----------------------------
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 /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/
#Ubuntu; Root File System: user@localhost:~$
sudo tar xfvp ./ubuntu-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/

Copy Kernel Image

Kernel Image:

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

Copy Kernel Device Tree Binaries

#user@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

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

File Systems Table (/etc/fstab)

#user@localhost:~/$
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

sync
sudo umount /media/boot
sudo umount /media/rootfs
