flashing multiple custom boards using multiple DKs?

[Ramy]

Is it possible to flash multiple custom boards using sagger DKs at the same time?, assume 2 custom boards and 2 DKs, would they be able to flash the custom boards in parallel?

Yes. This is possible with the serial number feature, e.g. --snr <serial_number> parameter in nrfjprog command line tool.

[Ramy]

using the --snr will direct the command to one of the DK!
but do you mean write the --snr twice, cause that didn't work either?, notice that I would like to flash the 2 boards at the same time

Please have a look at this application og GitHub.

Thanks a lot. it worked!

You need to issue 2 commands in parallel, with one serial number each.

can you suggest some way to adde more functions to that app? it only has program I tried to include other functions like memory write or memory read but the script itself failed before adding the functions and afterwards
anyway thanks for the assistance!
