Building Images

Note that the ost-microzed machine requires the meta-ost-xilinx layer that is part of meta-ost. Note: Building for this machine requires Yocto scarthgap version! 

Follow the Setup and Building guide to set up the build environment. Fetch board and processor specific repositories:

• meta-arm, github.com/Freescale/meta-freescale.git, branch scarthgap

• meta-xilinx, git://git.yoctoproject.org/meta-xilinx, branch scarthgap

• meta-xilinx-tools, https://github.com/Xilinx/meta-xilinx-tools.git, branch scarthgap

• meta-ost-real, https://gitlab.ost.ch/tech/inf/public/yocto/meta-ost-real.git, branch scarthgap

Next, add the layers to bblayers.conf

and change the machine definition in local.conf

The ost-microzed machine provides support for building Zynq7000 images with a flink bitstream, currently centered around use in the REAL project.

The PL is configured using the flink2 configuration/bitstream.

Getting Images

Prebuilt images can be obtained from our Linux Images page. Extract it and flash it onto a micro SD card.

Booting from the Image

Currently the instructions only cover booting from the micro SD card slot.

Insert the micro SD card into the board and supply it with power.

Developing for the Board

See SDK or eSDK.

Known Issues

RT kernel

Xilinx themselves don't provide an RT kernel and as such there seems to be no official support for it. While our fork with the RT patches applied mostly works, actually enabling full preemption breaks the ethernet functionality (specifically receving packets, sending seems ok) [Tracking Issue].

Accessing the Board

The login shell can be accessed through UART1 (USB mini on the board).

The root user is also available over ssh in development images (such as ost-devel image).
