Configuration to write external flash memory using nrfutil tool

[Alessio Lei]

I'm setting up a script we will use at production time to write some data to an external flash module connected via SPI to a nRF54H20.

I used the following as reference document https://docs.nordicsemi.com/r/bundle/nrfutil/page/nrfutil-device/guides/programming_external_memory.html?tocId=VZmfjI%7E3lJLxXfQxc5L%7E7g

I am passing the following JSON to nrfutil 2.19.0 (i used the structure passed in the example for nRF54L15 in the page above)

{
    "firmware_config": {
        "peripheral": "EXMIF"
    },
    "pins": {
        "csn": 195,
        "io0": 199,
        "io1": 197,
        "io2": 202,
        "io3": 201,
        "sck": 192
    },
    "flash_size": 8388608,
    "page_size": 4096,
    "sck_frequency": 6400000,
    "address_mode": "MODE24BIT"
}

and i get the error

Device error: Failed to load the external flash config: Configuration file parsing failed: missing field `reset` at line 12 column 5 (Generic)

Is it possible to have the expected JSON structure or a link where to find it?

Thanks,

Alessio
