Connect Metaware C Pro to NRF51-DK dev board to reprogram bootloader and flash
know that you do not support firmware development but you do give instructions
on how to flash your own firmware to the board. My problem is that I am trying
to flash a c pro using the NRF51 DK as recommended on your site (https://mbientlab.com/firmware/). The
description of the connections for this combination of boards is vague.
have (some are guesses as not detailed in guide on website)
pin 5 Vgnd <-> dk gnd pin
pin 6 V3v <-> dk P20 pin 1
pin 11 V3v <-> dk p20 pin 3
pin 12 Vgnd <-> dk p20 pin 8
pin 13 SWDIO/nReset <-> dk p20 pin 4
pin 14 SWDCLK <-> dk p20 pin 5
is obviously incorrect. The nrf51 dk board knows that there is an external
board present but cannot connect to it and I have tried a large variety of
tools and combinations to connect.
