Building U-Boot

The instructions and source files in both:

Zynq_Mini-ITX_z7100_Ubuntu_FAT_v2014_4_0.zip

and

Zynq_Mini-ITX_z7100_Ubuntu_FAT_v2013_4.zip

Are incorrect and I can't build U-Boot for this board (Zynq Mini-ITX z7100).

Has anyone got a working set of patches for the master branch of https://github.com/Xilinx/u-boot-xlnx.git?

Also why doesn't this repo contain support for this board?

Thanks,

Andy

Andy,
Are you using the version tags specified in the document? The instructions are specific to the builds specified, and should work fine in those versions. U-boot is constantly evolving, and the build procedure changes between releases.
Adding support for the Zynq Mini-ITX to the mainline u-boot repo (which will automatically be picked up by xilinx) is on the project list, but it is simply a matter of finding resources to complete the task.

Yes, I've created a branch based on the tags (for both v2013.4 and v2014.4) and neither version builds. The v2013.4 version is missing zynq-common.h and the v2014.4 version has some several issues.

Thanks,

Hi Andy,
Well, I was skeptical but when I tried the same flow that has worked innumerable times in the past, you are absolutely correct that it's entirely broken.
It appears that the u-boot hierarchy has been changed, and while I thought changes were supposed to be backwards compatible with existing tags, I guess they are not. Because this one certainly breaks the instructions for every previous version.
In the end the changes to the flow are not that severe, but it is easy to get lost if you aren't familiar with u-boot. We are currently in an update cycle for all the reference designs, so the next version will correct the problems created by the new hierarchy. However, to keep everybody who needs to build u-boot working, I will post the new files needed for the Zynq Mini-ITX 7045/7100, and a short instruction page on how to apply the files and build u-boot for your device.
Look for a new download called "U-boot update" at the top of the Ubuntu Desktop Linux Reference Design for the Zynq Mini-ITX.
Sorry for the issue, but thanks for bringing it to my attention. I was unaware things had changed. Please let me know how this works for you.

Thanks for the update Ron.

First, I think your instructions are incorrect in "To Build U-Boot:", step 2.

I think the syntax should be:

$ git checkout -b newbranch xilinx-v2014.4

See here:

http://stackoverflow.com/questions/10940981/git-how-to-create-a-new-branch-from-a-tag

And the files in your .zip aren't compatible with
the xilinx-v2014.4 tag.

I tried a more recent tag and I was able to build:

1. $ git checkout -b andyd xilinx-v2015.3
2. $ <copy files in your .zip>
3. $ make zynq_mitx_config
4. $ make

My next step is to create a boot.bin (with PCIe support) and make sure it boots on my board.

Thanks,

Andy

My boot.bin boots OK.

Thanks,

Hi Andy,
Yes, you are exactly correct. The tag name was missing from the checkout command, and that was causing all the problems. Thanks for pointing that out - much appreciated!
