zynq_zc706: bump U-Boot to xilinx-v2016.2
This is the latest release tag in the Xilinx repository, based on U-Boot v2016.01 in the mainline. It includes proper ps7_init_gpl.c/h in it, so builds working SPL without any manual intervention. BR2_TARGET_UBOOT_BOARD_NAME should be changed to zynq_zc706 since U-Boot now has separate defconfig files for ZC702 and ZC706 boards. BR2_TARGET_UBOOT_SPL_NAME should be changed to spl/boot.bin since the Zynq image support for the mkimage tool was upstreamed and it now generates boot.bin under spl/ directory.

uboot.bin -- U-Boot SPL w/ Xilinx boot.bin wrapper
|
||||
---------------------------------------------------
|
||||
Steps to create a working system for ZC706 board:
|
||||
|
||||
Due to licensing issues, the files ps7_init.c/h are not distributed
|
||||
with the U-Boot source code. These files are required to make a
|
||||
boot.bin file.
|
||||
1) make zynq_zc706_defconfig
|
||||
2) make
|
||||
3) All needed files will be available in the output/images directory.
|
||||
Create a FAT32 partition at the beginning of your SD Card and copy files:
|
||||
- boot.bin
|
||||
- u-boot.img
|
||||
- uImage
|
||||
- uramdisk.image.gz (should be renamed from rootfs.cpio.uboot)
|
||||
- devicetree.dtb (should be renamed from zynq-zc706.dtb)
|
||||
into your SD card
|
||||
4) boot your ZC706 board
|
||||
|
||||
If you already have the Xilinx tools installed, the following sequence
|
||||
will unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
|
||||
You can alter the booting procedure by creating a file uEnv.txt
|
||||
in the root of the SD card. It is a plain text file in format
|
||||
<key>=<value> one per line:
|
||||
|
||||
make zynq_zc706_defconfig
|
||||
make uboot-patch
|
||||
cp ${XILINX_SDK_LIB}/hwplatform_templates/ZC706_hw_platform/ps7_init.{c,h} \
|
||||
output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
|
||||
|
||||
Where ${XILINX_SDK_LIB} is ${XILINX}/SDK/${VERSION}/data/embeddedsw/lib.
|
||||
|
||||
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 ZC706. 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 executed.
|
||||
|
||||
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/
|
||||
|
||||
cp <output>/images/boot.bin /media/sdcard/
|
||||
cp <output>/images/uImage /media/sdcard/
|
||||
cp <output>/images/u-boot.img /media/sdcard/
|
||||
cp <output>/images/zynq-zc706.dtb /media/sdcard/devicetree.dtb
