Cannot flash nrf52 dk from different batch

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.

  • You may need a nrfjprog --recover -f nrf52 as the board may have entered a weird state after the failed flash attempts. I will try to get hold of a board here to try to reproduce. What are the markings on the nRF52 IC on your board? (The nRF52 is located inside the painted rectangle above the four buttons. Should be nRF52832 something something.)
