Cannot program 52840-DK with nrfConnect

[Niramas]

I have a 52840-DK  (PCA10056) connected over USB on Windows 10.   I am using IAR and can build and run demos from EW in this configuration but am having no success with nrfConnect.

nrfConnect v3.2.0 sees the board but does not load any info about the connected device nor does it allow any programmer functions.  I can load hexfiles (shown) but no programming.   I have just started with the Nordic tools so I am probably missing something basic (a driver maybe?).   How else would I get S140 onto the board?

Follow-up:  I changed the COM port from 20 to 4, in case the high number was causing difficulty.  This had no effect.
