Building zedboard images

Ok, I was able to build "world" but for some reason the u-boot-xlnx doesn't seem to incorporate correctly into the 9.0.2 tree I'm using.

Does anyone know the exact version of poky that is used ?

I had to make 2 minor casts in the elfutils sources, which I found odd, but the error was a char** being used for a float*.

Anyway, if anyone can even hear my plea for help in getting all my images together (I have a .bit file already for the FPGA), I would appreciate any input.

I get errors from fetching u-boot-xlnx, and just can't seem to get around them. Seems it fails when using the git protocol but will transfer with https, yet it doesn't like it if I change to https and set the proocol.

Any suggestions?

Wow, almost 5 days and not a peep from the zedboard folks...makes me wonder if another reference would have been more fruitful...:-(

Hi there,
Let me try and help. We have successfully built a Linux image to run on ZED board using Yocto and the xilinx meta layer.

Here are some notes from a colleague on how we did it.


BUILDING YOCTO XILINX ZEDBOARD
We are using Yocto 1.5.1 and 'dora' tags on all layers.

Config your local machine with packets needed to build Yocto Distro
- sudo apt-get install gawk wget git-core diffstat unzip texinfo build-essential chrpath

Download Yocto meta layer:
- git clone -b dora git://git.yoctoproject.org/poky.git

Download Xilinx meta layer:
- git clone -b dora git://github.com/Xilinx/meta-xilinx

Download meta-oe layer:
- git clone -b dora git://github.com/openembedded/meta-oe

Configure the machine in '~/poky/build/conf/local.conf' adding this line:
- MACHINE ??= "zedboard-zynq7"

Configure extra layers in '~/poky/build/conf/bblayer.conf' adding this lines:
- BBLAYERS ?= "
-   /home/user/poky/meta
-   /home/user/poky/meta-yocto
-   /home/user/poky/meta-yocto-bsp
-   /home/user/poky/meta-xilinx
-   /home/user/poky/meta-hob
-   /home/user/poky/meta-oe/meta-oe
-   "

Build Poky distribution:
- source poky/oe-init-build-env
- bitbake core-image-minimal

Files need to build the SD-card are inside directory '~/poky/build/tmp/deploy/images/zedboard-zynq7':
- u-boot.elf
- core-image-minimal-zedboard-zynq7-20131129153026.rootfs.ext2.gz.u-boot
- uImage
- uImage-zedboard-zynq7-mmcblk0p2.dtb

read how-to-build-sdcard from xilinx doc
http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/tree/docs/BOOT.sdcard?h=dora


Reference links:
https://github.com/Xilinx/meta-xilinx (see README)

I hope this helps.

Many regards,
Chris Young.

Chris,

Thanks for your reply, if you read this. I'm currently using the meta-topic layer and I really like the Changes which Mike Looijmans added to that layer. It boots the SD card at blazing speed, no timeout for uboot, it's really quick to boot on the SD. Mike leaves all the files you need in deploy boot to create an SD....

I'm working on the microZed right now and trying to get it up. I have both a 7Z010 and a 7Z020.

I will revisit this zedboard after I can get some time.

Cheers,

Goal to add newer kernel to Zedboard & u-boot in hopes of fixing the no sound issue.
Also adding the capability of dynamically downloading bit files to PL and the ability to generate
Poky and FPGA builds on single system.
gcc-4.7 to gcc-4.8

Required meta-topic & poky dora needed to upgrade Xilinx Tools from 14.4 to 14.6.

Problems in gnuradio-3.6.5, opencv & vlc in dora branch.

same thing, here, no response on any of my question !!

Thank you for posting the recipe. Is there a place where one can find a BOOT.INI file which match the Yocto build? I will eventually create my own BOOT.INI and FPGA peripherals, but I would like to make sure that I can run through the full toolchain to verify the procedure before rolling my own.

Hi ,
i have error with that configuration (Permalink), "ERROR: Task 670 ", what cold cause that. In order to avoid that, Im am trying to find meta-zedboard folder as in this link https://github.com/architech-boards/meta-microzed.git.

Eny advice will be help, thx in advance
