Hello Mariano,

I compile EPICS with Yocto 2.1 / Petalinux toolchain for the XILINX Zynq

Ultrascale.

My config file is attached. But it needs 3 additional macros:

GNU_HOST_ARCH=i686
GNU_HOST_OS=linux
are defined in my CONFIG_SITE.linux-x86.Common

GNU_HOST_ARCH_64=x86_64
is defined in my CONFIG_SITE.linux-x86_64.Common

(I use them in several embedded Linux cross compiler configs and did not

want to pull too many host specifics into a CONFIG.Common.* file.)

Also be aware that you have probably installed yocto somewhere else. Fix

SDK_DIR accordingly.

I could use this cross compiler only on a 64 bit host, but that should

not be much of a problem nowadays.

Best regards,
Dirk

Dear tech-talkers,

I am trying to create a Linux embedded distribution using Yocto

including epics-base.

Does anyone have a yocto meta-layer already implemented?

Thanks a lot
