Xilinx ZCU102 / ZCU104 / ZCU106 boards - ZynqMP SoC
***************************************************
This document describes the Buildroot support for the ZCU102, ZCU104
and ZCU106 boards by Xilinx, based on the Zynq UltraScale+ MPSoC (aka
ZynqMP). It has been tested with the ZCU102 and ZCU106 production
boards.
Evaluation board features can be found here with the links below.

How to build it
===============
Configure Buildroot: (use the command for the specific board)
$ make zynqmp_zcu102_defconfig
$ make zynqmp_zcu104_defconfig
$ make zynqmp_zcu106_defconfig
Compile everything and build the rootfs image:
$ make
Result of the build
-------------------
After building, you should get a tree like this:
output/images/
+-- atf-uboot.ub
+-- bl31.bin
+-- boot.bin
+-- boot.vfat
+-- Image
+-- rootfs.ext2
+-- rootfs.ext4 -> rootfs.ext2
+-- sdcard.img
+-- system.dtb -> zynqmp-zcu106-revA.dtb
+-- u-boot.itb
`-- zynqmp-zcu106-revA.dtb
How to write the SD card
========================
WARNING! This will destroy all the card content. Use with care!
The sdcard.img file is a complete bootable image ready to be written
on the boot medium. To install it, simply copy the image to an SD
card:
# dd if=output/images/sdcard.img of=/dev/sdX
Where 'sdX' is the device node of the SD.
Eject the SD card, insert it in the board, and power it up.
==============
Important Note
==============
The DDR memory on the original ZCU102 and ZCU106 boards is EOL.
The Buildroot defconfigs for these boards use the new DDR memory
which is configured by the u-boot spl initialization with the
Buildroot config options below.
New DDR Memories:
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu102-rev1.0"
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu106-rev1.0"
If nothing is printing upon boot, most likely it is because the
board has the original DDR memories. To fix the problem, modify
the Buildroot defconfig file to use the u-boot spl initialization
for the original DDR memory using the config below for the target
board.
Original DDR Memories:
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu102-revA"
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu106-revA"
