PHYTEC link board ETH¶
Overview¶
The link board ETH is an ethernet expansion board based on ENC424J600 ethernet controller and compatible with the Arduino UNO R3 connector. It was developed as an expansion component for the reel board. See reel board documentation for more information about link board family and how to connect it to the reel board.

Programming¶
Set -DSHIELD=link_board_eth when you invoke west build or cmake in your
Zephyr application. For example:
Using west:
# From the root of the zephyr repository
west build -b reel_board samples/net/zperf -- -DSHIELD=link_board_eth
Using CMake and ninja:
# From the root of the zephyr repository
# Use cmake to configure a Ninja-based buildsystem:
cmake -B build -GNinja -DBOARD=reel_board -DSHIELD=link_board_eth samples/net/zperf
# Now run ninja on the generated build system:
ninja -C build
