How to flash binary into nRF5340 DK external flash using nrfjprog command line tools.

[Kaushik Parsana]

Hello

I am working on to flash my firmware binary into external flash by using nrfjprog commandline tools.

I have used below command to program and verify the external flash programming.

1) nrfjprog --family NRF53 --program zephyr.hex --qspichiperase --log abc.log

2) nrfjprog --family NRF53 --verify zephyr.hex --log abc.log

But it gives below error, can anyone tell me what command should I have to use to program the external flash?

Hi,

Command qspieraseall can be used for erasing external flash.

nrfjprog --qspieraseall

Afterwards, you can proceed to programming the application. When programming, you could try adding --verify to the first line, like this

nrfjprog --family NRF53 --program zephyr.hex --qspichiperase --verify

After you erased external flash, you could also specify the core you want to use when programming

nrfjprog --family NRF53 --coprocessor CP_APPLICATION --program zephyr.hex --qspisectorerase --verify

Please let me know the results of the above-mentioned approaches.

Best regards,
Dejan

Hey Dejan

Thanks for the reply, I had tried those command and here is the attached result.

My end goal is to check the solution for external flash production programming point of view.

Hi Kaushik,

Have you tried using "nrfjprog --qspieraseall" instead of "nrfjprog --eraseall" as first command?

Yes, I tried for external flash programming case.
Do we need to modify QspiDefault.ini file for set external flash configuration?

Hi,

In one of your previous posts, it can be seen that you ran "nrfjprog --eraseall" instead of "nrfjprog --qspieraseall" from the command line.

4604.QspiDefault.ini

extFlash.hex

For your clarification, I had re-run the command and here are the attached result. also attached the extFlash.hex file and my QspiDefault.ini file for reference, My hardware is nRF5340 DK board and External Flash was MX25R6435FZNI - Macronix.

Hi,

You could try the following command

nrfjprog --family NRF53 --program zephyr.hex --qspichiperase --chiperase --verify
