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"
|
