Cannot flash nrf52 dk from different batch

Matts

Hi.

We just received few new nrf52 boards. They are same PCA10040 v1.1.0 as previous ones, but these have date of 2016.21 stamped on them instead of 2016.09. Problem is that I cannot flash these new ones with nrfjprog. The flashing starts but never completes. Drag&drop doesn't seem to flash it either, however I haven't tried the drag&drop method before with softdevice, so might be user error. But anyways we need to get the command line flashing working.

I'm using SDK v11 and s132 softdevice.
