nrfjprog in a daisy chain

Dash

When a Jlink programmer is connected to multiple devices (daisy chained) how do I specify which device is being programmed on the command line using nrfjprog?

Additionally, if I have two nrf52DK boards connected simultaneously I can get the serial numbers of each debugger using the nrfjprog -i option. How can I specify which serial number I want to use for programming operations using nrfjprog?

    Hi,

    You can use the -s command to select the debugger you want to use. From the documentation :

    -s --snr <serial_number> Selects the debugger with the given serial number among all debuggers connected to the computer for the operation. Must be combined with another command.

    Note that the nRF5x devices are programmed using SWD, and SWD does not support daisy-chaining.
