Thanks! Can you see the JLINK folder in the file explorer in Ubuntu? I have just tried hooking up an nrf52dk to Ubunt 16_04_3 running on Virtualbox &amp; I can see the JLINK folder without any issues at all.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116328?ContentTypeID=1Mon, 08 Jan 2018 19:34:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:202c6e0f-9f36-4401-986e-13edc30a25f9BillyBobJoe<p>You can install Ubuntu bash on windows without a VM. I am using MSYS2 via a VM which im using to compile Zephyr and using windows to flash the dev-kit.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116330?ContentTypeID=1Mon, 08 Jan 2018 13:40:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:041b4f50-d99c-4cba-b1d9-35535844137aBj&#248;rn Kvaale<p>Hi Billy, could you clarify what you mean by &quot;installed Ubuntu on Win10&quot;? Are you using a virtual machine (e.g. VirtualBox) or did you dual boot Windows and Ubuntu on the same machine?</p><div style="clear:both;"></div>
