nRF52840 custom board - CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

[Mathangopal]

Hi. I am currently having a nrf52840 custom board and tried to program the sniffer hex file. nRF programmer gave me couldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a). I tried to use nrfjprog by entering the command "nrfjprog -f NRF52 --recover --log". But, i get this:

Are you using an nRF91 DK to program an nRF52? Have you made sure the switch on the nRF91-DK is set to nRF52-position?

https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/hw_debug_out.html

[Mathangopal]

Hi. I am using nRF5340-PDK to program my nRF52840 custom board. I am using SWDIO, SWDCLK, GND detect and VTG pin from the nRF5340-PDK Debug out P20.

Connection

SWDIO nRF5340 - SWDIO nRF52840

SWDCLK nRF5340 - SWDCLK nRF52840

GND detect nRF5340 - GND nRF52840

VTG nRF5340 - 3v3 nRF52840

I was able to program the device using the HRS example given in the SDK and my custom code.

Ever since I program the sniffer hex file, I am getting this issue. 

Thank you for the reply.

[Kenneth]

Can you just double check that the voltage on the custom board is still 3.3V? 

Have you tried to do a power cycle of the PC, and only used the command line tools after restart? 

In general the PDK is no longer recommended for development due to using early engineering samples of the nRF5340, the final DK is now available for order. Though I don't see how that should affect what you are seeing. Do you have any nRF52-DK that you can try for comparison?

[Mathangopal]

I have switched to nRF52-DK.

Hi. I am using 3v for the board. I also tried with 3.3v. But still having the same issue.

I tried to power cycle the PC and use only command line tools still have the same issue.
