Hi,
i am currently starting development software for a new B&R board based on the ZYNQ7000.
To make live easier i want to try start with the Xilinx Evalboard ZC702, get there some experience to start afterwards with my own board.
I have allready built "zynq_zc702_defconfig" - but have no plan how to bring the build output to my board. Is it necessary to build some FSBL with the Xilinx SDK an merge the output with u-boot's output ? Or is it possible to take some SPL und U-Boot, burn it so SD-Card or QSPI flash and run ?
Either works fine.
For SPL use mmc instead of QSPI - qspi patches on the way to merge mainline.
mmc: build the source in mainline and download zynq boot.bin generator from [1] and copy boot.bin and u-boot-dtb.img on to sd card, thats it.

Hi jagan,
many thanks for response and help.
It is now bit more cleaner to me ... in final i wan't to use hw guys output (ps7_* files) and build my software. At this point i think, i don't need the Vivado or Xilinx SDK at all ... just my ARM toolchain and u-boot. Fine.
Yes.
For the beginning i will use mmc (or maybe jtag). Finally i must use qspi. I think the QSPI support can be found on your github [1].
I've downloaded [1] ... and run:
~/work/u-boot-zynq $ tools/zynq-boot-bin.py test.py -u <inputfile> -o <outputfile>
What is the input file ? For my understanding, i need 2 input files (SPL and u-boot), or i'm wrong ?
See this wiki [1] and just try qspi as well and let me know for any questions.

thanks!
Hi Jagan,
many thanks - with your help i got it work :-) I tried both, mainline u-boot and which one from openedev.
I observed a little issue on both versions. If i type "reset" or press the SRST_B button i get:
U-Boot SPL 2015.07-rc3-g0cf5d8d (Sep 18 2015 - 11:22:16) mmc boot zynq_sdhci_init: sdhci_host malloc fail MMC Device 0 not found spl: mmc device not found ### ERROR ### Please RESET the board ###
if i simple power on or press the POR_B button it works as expected:
U-Boot SPL 2015.07-rc3-g0cf5d8d (Sep 18 2015 - 11:22:16) mmc boot reading system.dtb spl_load_image_fat_os: error reading image system.dtb, err - -1 reading u-boot-dtb.img reading u-boot-dtb.img
