ultrazed recompile kernel

bbolen

I would like to recompile the ultrazed kernel to enable some gadget mode testing on the iocc carrier card.

I have found the zcy02 ( zu9 ) BSPs on the Xilinx web site. 

Will these work with a custom device tree file?  Can I pull the device tree file out of the existing 2016.2 BSP file?  If not then where do I get it?

I would like to use 2016.4, since we have other projects using it, but I can't find anythiog for the zu3. 

Is it just too new, or should I be looking someplace else.

Thanks!

    Hi Brettbolen,

    We currently only have support for the UltraZed 2016.2 BSP. You can find it at : http://zedboard.org/support/design/17596/131

    If you are interested in using a 2016.4 UltraZed BSP you will need to create it yourself. This post describes how to do so : http://zedboard.org/content/microzed-petalinux-20161-bsp

    Hi brettbolen,

    The 2016.2 PetaLinux BSP Josh mentioned above can be recreated using the build automation script that is available on our GitHub repository:

    https://github.com/Avnet

    You will need a copy of both the HDL repository to build the hardware platform with Vivado and also the software repository to setup the PetaLinux project but that entire build can be launched with software/petalinux/scripts/make_uz3eg_petalinux_bsp.sh

    Regards,

    when I create a bsp, I have a couple of options :  standalone or freeos.  If I want to create a BSP for linux, do I choose standalone  or is there an option I'm not seeing.

    My goal is to recompile the kernel for usb gadget support.

    Hi brettbolen,

    AFAIK, you cannot use SDK to create a Linux BSP.  This is what the PetaLinux tools are for.

    From a high level, this is what the tool flow would look like:

    1)  Design and implement your hardware platform in Vivado, then export to get the Hardware Definition File (HDF)

    2)  Create a new PetaLinux project and import the HDF file that you got from the Vivado export.

    3)  Run 'petalinux-config -c kernel' and turn on your desired USB gadget driver.

    4)  Run 'petalinux-build' to make sure that everything builds okay.

    5)  Run 'petalinux-package --bsp' to package your PetaLinux project up as a BSP container:

    petalinux-package --bsp -p <PETALINUX_PROJECT_NAME> --hwsource <HDL_PROJECT_FOLDER> --output <PETALINUX_PROJECT_NAME>

    This process is covered by the automation script that I mentioned in my earlier response above:

    https://github.com/Avnet/software/blob/master/petalinux/scripts/make_uz3eg_petalinux_bsp.sh

    I highly suggest looking through that BASH script as a reference to understanding the small details that are needed for creating UltraScale Linux BSPs.

    Regards,

    Kevin,

    What version of PetaLinux do I need to use to recreate the BSP/Linux I have that came with my UltraZed board?  It boots out of eMMC with the following:

    Xilinx Zynq MP First Stage Boot Loader

    Release 2016.2   Nov 30 2016  -  22:14:22
    ...

    I am not interested in the Vivado portion, at the moment, so is the system.hdf file that came with the UltraZed_PCIe_CC_Tutorial_2016_4_v1 zip file the one I want to use?

    Kevin,

    I want to just rebuild the BSP for our UltraZed,but not the stuff related to Vivado. I have installed the PetaLinux tools in /opt/petalinux-v2016.2-final/ (which matches the script file you mentioned) and loaded the hdl/software repos from git into /home/<username>/repos/hdl and software.

    Where am I supposed to run the software/petalinux/scripts/make_uz3eg_petalinux_bsp.sh from because there are hardcoded locations checked in the script files?

    Hello rgross,

    The Petalinux BSP that you can use to recreate the linux that came with your UltraZed Board it located here http://zedboard.org/support/design/17596/131 under the PetaLinux Board Support Package section labeled "UltraZed IO Carrier Card - PetaLinux 2016.2 Compressed BSP"
