| *************************************************** |
| |
| 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" |
