Programming external nrf5340 via nrf534 DK development kit and NRF Connect software.

[saeed mahvis]

Hello Sirs

I am using the NRF3540-DK development board to program an external NRF5340 chip. I have connected the RESET,SWDCLK,SWDIO,GND,3V pins of P20 connector on development

board to the external NRF5340.I have also derived the VTG pin on P20 connector by a 3V voltage to prevent the NRF5340 chip on the development board from any program changing.

By using the NRF Connect software I can program the external NRF5340 with no errors , but even a simple program like Blinky sample doesn't work on external NRF5340.

Incidentally the so called external NRF5340 is on the NORA-B101 module from Ublox. Would you please guide me in this regard . Thank you in advance for your invaluable support.

Hi,

Did you mean that you can program the 53 DK but not the external(NORA-B101) board?

Debug out on the nRF5340 DK

Do you gett any error message ?

Hi

Is there any other way to program NORA-B101 apart from development kit?

You could try to use the nrfjprog tool and try with terminal commands as an alterative to the programmer app. 

You can use other programmer\debuggers to write to the nrf53 devices over SWD interface with a SEGGER J-link device.
