nRF9160 DK schematic sheet 2 missing pin names for WP and HOLD of nRF91_EXT_MEM in the On-board interface (far right page 2)
could someone post what nRF9160 pins are used?

Found this in the infocenter along with the suggestion to use the test points to wire to GPIO. Moving on, now I need to find how to get the 52840 to switch the external memory to the nRF9160, I haven't found that information in the infocenter.

So the latest 9160DK and the use of NCS 1.5 external flash is supported out of the box. By default the the 52 is configure correctly, but it is in the Device Tree config that controlls if the external flash is enabled or not.
