Issues programming nRF5340 on a Custom Board

[RPDben]

Hi,

I am having issues programming my custom nRF5340 board and was hoping to get some advice on the issue.

When programming using nRF Connect for Desktop (Windows 10, nRF Connect v3.6.1, Programmer v1.4.8) I get the error message:

Could not fetch memory size of target devkit: Error: Error occured when get library info. Errorcode: CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

When using the following nrfjprog (v10.12.1) commands nrfjprog -e --log or nrfjprog --recover --log I get the attached logs.

When using J-Link Commander V6.98C I get the following Output:

SEGGER J-Link Commander V6.98c (Compiled Mar 16 2021 12:20:44)
DLL version V6.98c, compiled Mar 16 2021 12:19:26

Connecting to J-Link via USB...O.K.
Firmware: J-Link V11 compiled Feb  4 2021 12:59:17
Hardware version: V11.00

Type "connect" to establish a target connection, '?' for help

Please specify device / core. <Default>: CORTEX-M4
Type '?' for selection dialog

Speed>
Device "CORTEX-M4" selected.


Connecting to target via SWD
Cannot connect to target.
J-Link>

I have checked the capacitors around the chip are showing +3V and the J-Link commander trace also shows a +3V reference.

Any help would be much appreciated.

Thanks,

Ben

Hi Ben, 

What are you using to program the custom board? How are you connecting the custom board to the programmer?

Kind regards,
Øyvind

[RPDben]

Hi Øyvind,

I am using a Segger J-Link v11.0, this is connected to the board via a TAG-Connect cable wired to SWD.

Thanks,

Ben

[Øyvind]

Have you been able to program the board before? What voltage are you running, and have you verified that the board is powered? Have you had any review of the board layout?
-Øyvind

[RPDben]

No, I only received the board today. I am running at +3V and have verified the board is powered (caps around the nRF53 are at +3V) and also that the VTref on J-Link Commander is reading +3V.

The schematic and board layout have been reviewed by a Nordic engineer.

Thanks!

[Øyvind]

Then my next question is why you are connecting to the device using Cortex-M4, the nRF53 is a Cortex-M33. Please change the device to corresponding device:
