Create project

1	vivado -mode batch -source scripts/create_project.tcl

Output project: Vivado_PE1/MercuryXU5_PE1.xpr

Note

To compile project enable “Specify MMCM M and D on Advanced Clocking Page…” on DDR4 SDRAM (MIG)

Kernel build

Kernel repository: https://github.com/enclustra-bsp/xilinx-linux (4.14.0)
Checkout release v1.8.2

1	git checkout v1.8.2

Build Linux kernel

export PATH=/opt/aarch64-none-linux-gnueabi/bin:\$PATH
export CROSS_COMPILE=aarch64-none-linux-gnueabi-

make ARCH=arm64 xilinx_zynqmp_defconfig
make ARCH=arm64 menuconfig
make ARCH=arm64 -j5 Image dtbs modules
make ARCH=arm64 -j5 modules_install INSTALL_MOD_PATH=/media/tortone/ROOTFS/

Output file: arch/arm64/boot/Image

Device Tree

Checkout release 2018.3

1	git checkout xilinx-v2018.3

Generate a device tree from reference Vivado project

hsi

open_hw_design MercuryXU5_PE1.sdk/system_top.hdf

set_repo_path /home/tortone/devel/training/zynq-linux/device-tree-xlnx

create_sw_design device-tree -os device_tree -proc psu_cortexa53_0

generate_target -dir my_dts

Compile device tree blob (.dtb) from device tree source (.dts)

cd my_dts
cp deployment/device-tree/* .

cpp -nostdinc -I include -I arch -undef -x assembler-with-cpp xu5.dts > system-top-preproc.dts
  or

U-Boot

U-Boot repository: https://github.com/enclustra-bsp/xilinx-uboot (2019.1)

export PATH=/opt/aarch64-none-linux-gnueabi/bin:\$PATH
export CROSS_COMPILE=aarch64-none-linux-gnueabi-

make enclustra_zynqmp_mercury_xu5_defconfig
make menuconfig
make -j5

Output file: u-boot.elf

Important

Verify that bootargs parameter contains ‘clk_ignore_unused’ otherwise ETH1 will not work !!!

U-Boot scripts

In u-boot-xlnx/bscripts there are .scr files (U-Boot scripts) to boot from different devices

FSBL, PMU and BL31

Refer to notes Zynq Linux

boot.bin
