I was not able to follow the instructions and get a working Zephyr toolchain on either the windows or the windows for linux subsystem. However, having done the research I was able to find a good responsive support from the Zephyr channel on Slack. As is often the case I had some misconceptions from the instructions and the toolchain was fickle. After the support from a couple of men we did get my toolchain working consistently. One such misconception I had is that setting the environment variable and its path was permanent but is only valid for the life of the command line terminal. I took both my set statements and placed them inside a batch file. Now, I cd into the project directory and set both of these.

cd c:\zephyr\zephyr

set ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb

set GNUARMEMB_TOOLCHAIN_PATH=c:\gnu_arm_embedded\7-2018-q2-update

Hi,

You need to use -DBOARD=nrf52840_pca10056 if you are building code for the nRF52840 DK, or are using a different development kit with a daplink programmer?
