Pir2s - can not connect to the serial console

Hi Community,
i am pretty new to the topic. I have a question which is not directly regarding to the problem of the thread opener but i think also short circuit.

But. I have the pir2s and did the same like you to install ipfire on the machine. But i can not connect to the serial console.
I bought the usb uart TTL adapter connect the three pins. Used putty /minicom no chance to get any output of the little bastard :wink:

May you give me an hint idea or link to an document?

Thank You very much

Hi @jenswbn

I follow the connection scheme of the NanoPI R1, that is, I put the colors in Gr, Tx and Rx according to the image.

Connect a USB-TTL uart cable like this:
G - Ground - Black
V - Volts - don't connect
T - R1 Transmit - PC rxd Receive Data - White (or yellow)
R - R1 Receive - PC txd Transmit Data - Green (or orange)

Now you can use the same procedure as other serial devices to setup.
minicom --device /dev/ttyUSB0
Set for baud: 115,200 parity:8 data:N stop:1

If you do it with Putty, put the corresponding COM port and 115200 in Baud.

With that it should work.

This pic is from the R1S but the serial console on R2S is the same


Hi, thanks for your replies. I think i see my problem. It sits right in fron of the monitor :wink: i didnt put the connection like RX and Destination TX which is logical. But after many hours of work sometimes…

update…since putting the correct TX/RX it works and i could configuere the beast . Great. Thx
