Enumerate OpenSDA serial number

I've noticed that when connecting more than one FRDM-KW41Z to my computer they all get the same OpenSDA/JLink serial number. This makes it impossible to differentiate between two boards when debugging or flashing using JLink. Is it possible to configure the OpenSDA serial number on the board and give it a unique number?

On the real J-Links every J-Link has its own unique serial number.

I don't think it is possible to change that serial number, as it is the one programmed into the J-Link firmware binary.

At least on machine (Windows 10) I can differenciate them with the order they show up in the list/drop down, if they are always connected to the same USB port.

I hope this helps,

Erich

Yes, I've also noticed that the "real" J-Link has a unique serial number. Since OpenSDA is Open Source I was hoping to find a solution to generate new serial numbers. I was also hoping for it to be stored in the configuration memory area of the J-Link, i.e. visible when running J-Link command rconf. If so, it would be possible to set a new serial using wconf. But no luck finding it so far.
