This is the buildroot board support for the Avnet Zedboard. The Zedboard is
|
|
a development board based on the Xilinx Zynq-7000 based All-Programmable
|
|
System-On-Chip.
|
|
|
|
Zedboard information including schematics, reference designs, and manuals are
|
|
available from http://www.zedboard.org .
|
|
|
|
The U-Boot firmware for the Xilinx Zynq All Programmable SoC depends
|
|
on some propietary code. This dependency consists of a pair of
|
|
files are available from the Xilinx SDK installation.
|
|
|
|
You will need these files from Xilinx SDK installation to generate
|
|
the U-Boot firmware:
|
|
ps7_init.c
|
|
ps7_init.h
|
|
|
|
Buildroot will create the following files and place them in the
|
|
<output>/images directory.
|
|
zynq-zed.dtb
|
|
rootfs.cpio.uboot
|
|
uImage
|
|
u-boot.img
|
|
boot.bin
|
|
|
|
|
|
uboot.bin -- U-Boot SPL w/ Xilinx boot.bin wrapper
|
|
---------------------------------------------------
|
|
|
|
Due to licensing issues, the files ps7_init.c/h are not able to be
|
|
distributed with the U-Boot source code. These files are required to make a
|
|
boot.bin file.
|
|
|
|
If you already have the Xilinx tools installed, the following sequence will
|
|
unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
|
|
|
|
make zedboard_defconfig
|
|
make uboot-patch
|
|
cp ${XILINX}/ISE_DS/EDK/sw/lib/hwplatform_templates/zed_hw_platform/ps7_init.{c,h} \
|
|
output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
|
|
|
|
After copying these files into the U-Boot source tree, you can
|
|
continue the build with:
|
|
|
|
make
|
|
|
|
*Notice*
|
|
While the build will successfully complete without the ps7_init.*
|
|
files, the uboot.bin file generated by this configuration will not
|
|
function properly on the Zedboard. Therefore, it is imperative that
|
|
the ps7_init.* files be copied into the U-Boot source tree any time
|
|
the clean, or uboot-dirclean targets are made.
|
|
|
|
|
|
Resulting system
|
|
----------------
|
|
A FAT32 partition should be created at the beggining of the SD Card
|
|
and the following files should be installed:
|
|
/boot.bin
|
|
/devicetree.dtb
|
|
/uImage
|
|
/uramdisk.image.gz
|
|
/u-boot.img
|
|
|
|
|
|
All needed files can be taken from output/images/
|
|
|
|
boot.bin, uImage and u-boot.img are direct copies of the same files
|
|
available on output/images/
|
|
|
|
devicetree.dtb is just zynq-zed.dtb renamed.
|
|
|
|
uramdisk.image.gz is rootfs.cpio.uboot renamed
|
