flash redbear nano/sparkfan nrf52832 breakout with nordik sdk, How;

[NK99]

Hey, i have a redbear nano and a nrf52832 breakout board and i want to program them using nordic sdk. Can you pls provide me with instructions?

Is this the nRF52 breakout board you have? Do you have the MK20 USB Board?

Hi,

You will need a programmer to flash the devices. Both the redbear nano and the nrf52832 breakout-board have a SWD interface that you use to connect to a programmer. If you have a nRF5x Development kit, you can use the on-board debugger/programmer(SEGGER J-Link OB) to flash your devices using the Debug output connector. You can also use other programmers that support SWD.

Yes this is the one and i have the mk20 too

Can i do this with keil? and some other jtag programmer for another kit? Or do i have to get the nrf5x dev kit?

I think the MK20 supports CMSIS-DAP, so you can try to select "CMSIS-DAP Debugger" in the Keil "Options for target" ->Debug tab.
