Nrfjprog won't show VCOMs for nRF5340 Audio DK

[PBD5]

I have three nRF5340 Audio boards (PCA10121, 1.0.0). Most of the times, nrfjprog --com won't detect VCOMs on these boards. The VCOMs are there, because I can see them in Device Manager and I can open them using e.g. Putty. Occasionally, the VCOMs are detected, but I haven't observed any pattern explaining when they would and wouldn't be detected. 

Other nrfjprog features (showing board ID, flashing the boards...) work just fine. 

I use Win 11, and use the following nrfjprog version: 

$ nrfjprog -v
nrfjprog version: 10.19.0 external
JLinkARM.dll version: 7.80c

Could you please help me with investigation of this issue? 

Thanks!

Hello,

Yeah, that is an unfortunate issue with the Audio DK. It has an unsupported extra com port, that is structured in a way such that it breaks our detection mechanism. 

"nrfjprog --com" currently doesn't work with our Audio DK. Sorry about this.

Hello Elfving,

thank you for your reply. I understand. I have two more questions. Is there any workaround? Because as I said, sometimes it works for me. Right now it does work fine for one of the boards I have (it detects VCOM0 and VCOM1). 

And is there any plan to fix in the future?

Thanks!
