PATCH v2 1/1 board: add support for Xilinx zc706

This is a Xilinx Zynq (xc7z045) development board, based on Xilinx Zynq (xc7z045).

This support is based on Avnet Zedboard defconfig/readme.

+This is the Buildroot board support for the Xilinx ZC706. The ZC706 is
+a development board based on the Xilinx Zynq-7000 based All-Programmable
+System-On-Chip.
+
+ZC706 information including schematics, reference designs, and manuals are
+available from
+http://www.xilinx.com/products/boards-and-kits/ek-z7-zc706-g.html.
+
+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 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
+cp <output>/images/rootfs.cpio.uboot /media/sdcard/uramdisk.image.gz

PATCH v2 1/1 board: add support for Xilinx zc706

Jordi,

Quoted 1 line · jordi montagne

up

Thanks Jordi. However, there is no need to "up" a patch only 4 days after it has been submitted. Waiting ~2 weeks is probably more appropriate.

You can see the state of our patch queue at
http://patchwork.ozlabs.org/project/buildroot/list/. There are 300+ patches currently waiting there.

If you want to see your own patch merged faster, then the best way is to participate by reviewing and testing the patches submitted by others.

Best regards,

Thomas

Sorry for the noise. I fear I do not have the level required to review ...

It's not just reviewing, also testing patches is very useful! See
http://nightly.buildroot.org/manual.html#_reviewing_and_testing_patches

Regards,
Arnout

I've finally applied your patch, after some minor changes:

[Thomas:
- minor fixes in the readme.txt
- rename defconfig from zc706_defconfig to xilinx_zc706_defconfig.]

However, in the mean time, the zedboard_defconfig has been quite significantly improved. Especially, it no longer requires the special ps7_init.c/h from the Xilinx SDK. See the following commits for details:

http://git.buildroot.net/buildroot/commit/?id=ee845a46e2e7d60ac52c38555c183020ce8cd711
http://git.buildroot.net/buildroot/commit/?id=aabe23f8615f065d7bf62801d38efd17125e78d0

http://git.buildroot.net/buildroot/commit/?id=c139f0cce7d78e21b67f4649541a25ae8b5251f4

Maybe you can have a look at the new Zedboard support and update the ZC706 support as well?

Thanks a lot!

Thomas
