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,

    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?
