Getting Started - Running Examples. Ninja not flashing

[Doroana]

So I was following the documentation.
Installed everything successfully.
And now I am trying to send the program to the nrf52840.

However when I do ninja flash<program> I get:
ninja: no work to do.

Following the tutorial I should get at least a list of connected devices.

I am using:
- Windows10
- nRF5 SDK for Mesh v4.0.0
- nRF5_SDK_16.0.0_98a08e2

Don't know much about Windows10 but the flash works in my Linux (Ubuntu 16.04) VM. Which soft device are you using for the cmake/ninja commands? s140_7.0.1?

[Doroana]

Yes I am using that soft device version.

With the VM your device is detected?

With the VM device I have this:

But probably is not recognizing due to another problem

Maybe your 52840DK was already "claimed"  by Windows10? Can you switch back to windows desktop, then unplug the 52840DK, then switch to VM, then plug in the 52840DK (should see some kind of usb icon pops up in the VM Linux desktop)?

[Doroana]

So I installed ubuntu in another machine...

And I have it connected via usb cable. But when I try to flash it does not recognize any device.

Do you see JLink* or JFlash* in your /usr/bin? Also, what's your nrfjprog version i.e. nrfjprog --version

[Doroana]

I got this:

Since I am seeing the nrf52840 as a folder, is it possible to flash programs by copying files to the folder?
I know that in some controllers you can do that by just dragging the elf or bin file.

I dragged the .elf from this folder but as expected did not work...
