disable unknow port

[dsyleixa]

Hello guys,

I would like to disable one port on my RaspberryPi 3 model B, meaning shut the current given to it. But I don't know the name of it. May someone could help me to find a solution?
That's the port in the red circle on the picture link below..

That's the DSI port, it won't have any current flowing unless you have something plugged in to it. So its effectively disabled automatically.

Hey,

But, If I use an antenna connected to an oscilloscope I've some emnassion electromagnetics which come from it :/
i'm pretty sure that my emission electromagnetic doesn't come from my processor..

Thanks

Could it come from the wifi antenna (that's the white rectangular thing just above the DSI connector in your image)

Hey again,
Currently no solution but the wifi is now disable and there are no electromagnetic emanation from it. I really think that the EM come from DSI port. I checked the signal near the power consumption plug and it's not the same signal.. annoying ..

thanks

Did you shut down the Bluetooth as well? That uses the same chip as the WiFi.

Hey,

Yes, I wrote

Code: Select all

pi3-disable-wifi
pi3-disable-bt

in the /boot/config.txt , before my post.
It's a noisy signal without apparent information.
