NRF Connect error

[Angry_Oatmeal]

Hello everyone,

I'm having an issue of trying to connect via NRF Connect to my nrf52840 DK boards, but I am encountering the following error messages.

Core0: Error while reading non-volatile memory: Error: Error occured when read. Errorcode: CouldNotCallFunction (0x9) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

Error when getting device info: Error: Error: Error occured when read. Errorcode: CouldNotCallFunction (0x9) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

Error when closing nrfjprog: Error: Error occured when close opened device. Errorcode: CouldNotResetDevice (0x5) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

Are there any suggestion on getting past this issue. 

Thank you very much,

Hi,

Could you check which JLinkARM.dll version you are using?

Use the nrfjprog command:

nrfjprog --version

Hi Jared,

Apologies for the late response. The JLinkARM.dll is version 6.80a.

Thank you,

Could you try flashing the board by using nrfjprog directly and share the log? With the  nrfjprog command:

nrfjprog --program <HEX> --sectorerase --log

Apologies for the very long delay. I lost track of this question after the new year.

I have since fixed the issue by running nrfjprog --recover.

However, I was not aware of the nrfjprog --program <HEX> --sectorerase --log command, and will use it in the future for debugging if there is ever a scenario where nrfjprog --recover does not work.

Thank you,
