Issue programming my board with the nrf9160

[galook]

Hello,

I have designed this schematic according to reference designs provided by Nordic Semi, however I might have failed as I am unable to flash the main module. I should mention I am a beginner, however not a complete beginner, as I've created functioning PCBs in the past.

I am flashing it using the nrf9161DK via SWD and I am sure the connections are correct. Still, the Programmer app of Nordic SDK doesnt recognize the new board with the nrf9160

The following is the log file of "nrfjprog --eraseall --log" with the DK connected by USB to the host computer and my board connected to the DK by the P20 pins

Hi,

 

The jlink log shows that the debugger is not able to connect to the DUT.

 

I am flashing it using the nrf9161DK via SWD and I am sure the connections are correct. Still, the Programmer app of Nordic SDK doesnt recognize the new board with the nrf9160

The nRF9161-DK uses 1.8V by default:

https://docs.nordicsemi.com/bundle/ug_nrf9161_dk/page/UG/nrf91_DK/hw_description/ext_programming_support_p19.html

 

Is your external board "VIO" connected to 3.3V or 1.8V?

 

Kind regards,

Håkon

My boards' VIO is connected to the "3V3" net, as it is in the picture, but as I'm connecting this net directly to the "VTG" pin on the Nordic 9161 DK, the "3V3" should actually have 1.8V on it.

The only time it would have 3.3V would be either if I would connect this voltage directly, which I don't, or if I would connect a higher voltage (e.g. 5V) to the input net of the LDO (which I also don't)

So to my knowledge on VIO my custom board has the same voltage as VTG on the 9161DK - that means 1.8V

[Håkon Alseth]

Hi,

 

"VTG" pin on the DK does not provide any voltage, but it is a input for the nRF91-DK.

Your custom board shall provide its VIO voltage to the VTG pin.

 

Could you measure and verify what your voltages are?

 

Kind regards,

Håkon

Hi, 

on my custom boards' VIO pin (in VDD net) I connect both the VTG and VDD pin from the nrf9161 DK - and the DK is powered from USB. I just measured it and my custom board has 1.8V on VIO

Hi,

VIO is 1.8V, but you connect VTG to your VDD.

You should provide VIO to VTG.

 

How many of your boards behave like this?

 

Kind regards,

Håkon
