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.

If daisy chaining is not supported then how does the procedure in this link work?How does the SWD know which nrf52 device it is programming since there is one on the nrf52DK and one on the thingy52?
