Hi Nate,

   It looks like the pentalinux could be based on the Yocto project.
So, the generic procedure you can follow.

   * Build the SDK (Chapter 11)
     Try to understand environment-setup-aarch64-xilinx-linux in order
to extract EPICS building variables.

    Two examples you can find may not be right these days, but it
could be good starting point for your environment.

     https://github.com/icshwi/e3-base/blob/master/configure/os/CONFIG_SITE.Common.linux-corei7-poky
     https://github.com/icshwi/e3-base/blob/master/configure/os/CONFIG_SITE.Common.linux-ppc64e6500

   * Install your cross compiler
   * set their path in CONFIG_SITE.XXX files. One example for
linux-corei7-poky. The cross compiler path is /opt/cct/2.6-4.14, so I
set the path in CONFIG_SITE.Common.linux-corei7-poky such as
     CC_POKY_TOOLCHAIN_PATH = /opt/cct
     CC_POKY_TOOLCHAIN_VER = 2.6-4.14
    * put your CONFIG_SITE.Common.XXXX in EPICS_BASE/configure/os
    * Set the following variable according to your arch in
EPICS_BASE/configure/CONFIG_SITE
       CROSS_COMPILER_TARGET_ARCHS =

    * Then "make"

    In addition, you have to add your own arch into
src/tools/EpicsHostArch.pl if you would like to use it.

    HTH,
    Han

SDK no longer exists in it's previous likeness and the cross compiler is no longer included in the Petalinux tools.  I am an EPICS newbie and this is my first attempt at cross compiling for the Zynq arm.  Any pointers or advice is appreciated.  I apologize if this message is redundant.
