Hi all,
I have a custom board running on nrf9161. I need to flash the custom board with the NRF9160-DK. But I am running into some issues. the development is at early stages and there are too many failure points and variables. So I just need to be sure at every step what each error means.
One question I have is about the connection between the target board and the DK. I have not connected the VDD (on P20) since my target board is powered by an external USB source, I have only connected VTG. Is it ok ?
I have set SW9 to 3v since I powered my nrf9161 with 3.3v.
On my customn board I've exposed swdio swdclk gnd and 3.3v
so my wire :
nrf9160-dk custom board
SWDIO -> SWDIO
SWDCLK -> SWDCLK
GND -> GND
VTG -> 3.3V
But when I try to connect to my custom board with nrfprogrammer v4.4.0 i got
14:56:33.853 Error: Failed with exit code 1. Failed to device info one or more devices: * 960082325: [jlink] JLINKARM_DLL_ERROR, code: Nrfjlink.
