Hi,

From the nRF52840 DK Hardware description:"To use the GPIOs for a purpose other than the onboard external memory and have them available on the P24 connector, six solder bridges (SB10–SB15) must be cut and six solder bridges (SB20–SB25) must be shorted".

So, you have to cut six solder bridges and also solder six others for it to work.

regards

Jared
