mkit use debug out P20 program standalone third part brd

[jjww]

HI I am trying to use mkit as programmer by P20

FOR third part BLE brd

VDD---mkit.vdd GND--mkit.gnd SWD--P20.4 SWC--P20.5

bisides, for P20.3(SH_VTG) connected to mkit.vdd P20.8(SH_GND-DETECT) connected to mkt.gnd those two pins are used to detect external brd connection as my understanding.

but the mkit still program the nrf chip on its own brd instead of external brd, May I know what else should I do?

Thanks

I have connection ref of other downloader

Hi,

Please see this blog post on programming the beacon kit with the nRF51 DK, it describes what you want to do. Be aware that we do not support programming third party chips(non-Nordic) with the DK.

Best regards,

Øyvind

The chip is NRF51822

Seems the problem is either P19 or P20, does not detect external brd. The ibeacon brd does not have the 6-pin header, which cause $40.. it is crazy... I have not figure out how to program it yet since the solder pad there already melt by mis-operation.

hi,jjww: P20 is OK ?? all the information is about using P19, the interface of P19 is so small. so it had better use P20 for program or debug external board
