Some tips to fix this problem
Nordic’S board no : PCA10056 (nRF52840)

Raytac’s board no : MDBT50Q-DB-40 (nRF52840)

3. Update the version of nRF Connect for desktop.
nRF connect for desktop V4.1.2
Programmer V3.0.9


4. Add jumper wire for GND shown as the below red arrow to avoid the different power reference between these 2 boards.

5. Make sure that IDE cable connects correctly. Red edge of IDE cable should connect to PIN 1 of both boards.


6. Supply power to VDD of Raytac’s demo board before flashing.
