nrfjprog Specifies whether the device can be specified using the (--snr) parameter

[ChuckRui]

Hi,

Because the efficiency of the production of Matter burning program is too slow.

we want to insert multiple devices in the production environment to burn at the same time.

But because of the reason of one machine and one code, this involves the problem of specifying the device when it needs to burn.

I know that the SN number is the only difference between each device (can be seen via the "nrfjprog --ids" command)

I have tried the following two commands but neither of them worked and each time a box pops up asking me to select the device.

1.nrfjprog -s 150710432 -f nrf52 -program 1.hex --verify

2.nrfjprog --snr 150710432 -f nrf52 -program 1.hex --verify

When I have only one device connected to my system, using the -n parameter can specify it

But when I have multiple devices connected to my system, using the -n parameter has no effect, of course, using the --snr designation has no effect, and still a prompt box will pop up asking me to select a device to execute the command.

So is there any way to specify a device to execute a command.

Hello,

First of all, here is some further info on production programming in case you haven't had a look at it.

I am not an expert on this myself, but I just tried to reproduce what you are seeing on my side here, and I don't think I am seeing the issue here. I just tried this by using the default command that is used by the extension.

Could you try this:

• Connect two DKs to the computer
• Open an nRF Connect Terminal from VSC
• Run "west flash -d c:[whatever the path to your buildfolder is] --skip-rebuild --dev-id [the ID of your nrf]"

This flashes the right DK every time. Though this is using "west" instead of "nrfjprog",  maybe that has something to do with it. Though please give it a go and let me know if it works for you.
