Hi,

I have one of boards and would like to get mainline U-Boot booting on it.

I have followed the instructions for creating a BOOT.BIN file comprised of:

- boot.elf
- .bit file
- u-boot.elf

and putting it on a a micro-SD card.

This works OK with the diligent master branch from github. I can boot normally.

However this is 2013.10. Mainline U-Boot uses device tree so
presumably the elf file does not work. I expect we need to use
u-boot-dtb.bin.

However since this is not an elf file I'm not sure how to build the
image using the 'Create Zynq Boot Image' tool.

I don't see any instructions in REAME.zynq about how to create an SD card.

Any pointers please?

Regards,
Simon

I have a Zynq ZC706 board.

The follwing is what I tried to run u-boot mainline.


I hope it will work for Zybo board, too.


[1] If you are using Xilinx hardware tool (Vivado or ISE)
    you can generate  ps7_init.[ch] or ps7_init_gpl.[ch].

    Copy the C file and the header into borad/xilinx/zynq directory


[2] Build

    make zynq_zybo_defconfig  && make


[3] Download the python script to generate boot.bin

   git clone git://github.com/Xilinx/u-boot-xlnx.git

    Copy  tools/zynq-boot-bin.py   to  ~/bin  or somewhere you like



[4] Generate boot.bin

zynq-boot-bin.py -o boot.bin -u u-boot/spl/u-boot-spl.bin


[5] Copy  boot.bin and u-boot-dtb.img  to your SD card




Please give it a try.

The problem about the instruction above is FPAG bit file is not loaded.



Another way instead of [4] might be:


Describe foo.bif as follows

image:
{
        [bootloader]fsbl.elf
        fpga.bit
        [load=0x04000000,startup=0x04000000]u-boot/u-boot-dtb.bin
}

and 
$ bootgen -image foo.bif -w on -o boot.bin





I have not working on Zynq these days.
I hope Michal can support us.





Best Regards
Masahiro Yamada

I think the best what you can do is simple disable CONFIG_OF_CONTROL
from mainline u-boot and do not use now.
This is what I do in xilinx tree but OF_CONTROL is also working fine
but needs some setup.

Zybo will be just the same.

In future I want to move this script to be the part of mkimage
but it has low priority now.

yes - but if you use xilinx tree I have also added support for loading
bitstream by SPL. I just haven't sent it to mainline yet.
But you can simple load bitstream in full u-boot which is fully supported
in mainline.

yes - this should also work.

why not? :-)

Simon: Let me know if you need any my help on this.
I have zybo here that I can try it.

Thanks for your help!

Here's what works for me:

CROSS_COMPILE=/opt/xilinx/SDK/2014.4/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-
make O=b/zynq_zybo zynq_zybo_defconfig

CROSS_COMPILE=/opt/xilinx/SDK/2014.4/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-
make O=b/zynq_zybo  -j10 -s

/opt/xilinx/SDK/2014.4/bin/bootgen -image try.bif -w on -o boot.bin;
cp boot.bin  /media/sglass/A097-A1D5/BOOT.bin; cp u-boot-dtb.img
/media/sglass/A097-A1D5/.

try.bif:
image:
{
[bootloader]/vid/software/devel/zynq/play/play.sdk/boot/Debug/boot.elf
/vid/software/devel/zynq/play/play.sdk/design_1_wrapper_hw_platform_0/design_1_wrapper.bit
[load = 0x04000000,startup=0x04000000]/vid/software/devel/zynq/u-boot-dtb.bin
}

I'm a bit unclear why I say u-boot-dtb.bin in the try.big file but it
actually loads u-boot-dtb.img.


If I use the zynq-boot script I can do this:

zynq-boot-bin.py -o boot.bin -u spl/u-boot-spl.bin
cp boot.bin  /media/sglass/A097-A1D5/BOOT.bin; cp u-boot-dtb.img
/media/sglass/A097-A1D5/.

and then I get a message from SPL and it boots also. I'm not sure why.

Regards,
Simon

what's boot.elf here? Is it u-boot SPL?

if boot.elf is u-boot-spl then you don't need to add u-boot-dtb.bin to
BIF at all because in MMC mode u-boot-dtb.img will be loaded instead.

u-boot-spl.bin is placed to OCM. In SD/MMC node SPL loads u-boot-dtb.img
from SD to DDR and jump to it.
