No device detected, or readback protection may be set

[Farsley]

I am just trying to program my sample nRF52810 using a PCA10040 devkit. I get the message "No device detected, or readback protection may be set" Pressing the Recover button does not correct the problem.

Please can you tell me what might cause this

Can you give me a bit more information? Are you flashing the softdevice using nrfgostudio? Which SDK are you using? Have you checked devzone for any similar posts?
