Hi Bob,

Sorry - we missed your post when you made it and have just noticed it. Is this still an issue for you? If so - have you always been able to program the NRF52_DK or is this the first time you are having problems?

Are you seeing the board show up as a mounted drive on your host system?

It's quite possible that you need to update the interface firmware as described here:

I use the nRF52_DK for the first time. So I think it would be wise to start with a demo to see if all settings and interfaces are working. However, even without any target connected, the compilation of BLE_Button failed. Error: Target "NRF52_DK" is not recognized

Interestingly that project appears to be tied to a nRF51 target so it is generating an error! With your platform set to nRF52_DK select "New" > "New Program". Then any of the Template projects for the nRF52-DK should build just fine. Most of those are developed for Mbed OS2 and we suggest selecting one for Mbed OS5.

If you move to the command line interface we have a broader set of examples here:

Sorry Bob my last comment fell victim to a poor choice of characters... it should read:
