RE: nrfjprog error for merged_domains.hex on nRF5340

Hi Mary,

Older versions of nrfjprog do not support programming both cores simultaneously. You must use v10.21.0 or newer for this. You can download newer versions from here: https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download

You can also program the application and network core separately by using the firmware images for each core. Typically, these will be located in build/zephyr and build/<netcore_image>/zephyr. For example, for Peripheral LBS:

Network core:

nrfjprog -f NRF53 --coprocessor CP_NETWORK --program build/hci_ipc/zephyr/merged_CPUNET.hex --chiperase

Application core:

nrfjprog -f NRF53 --program zephyr/merged.hex --chiperase

Reset the device:

nrfjprog --pinreset

Make sure to program the network core before the application core if you program them separately.

Best regards,
Marte

That nrfjprog command is missing its --family nrf53 argument. That is why you get the address error.
