Actual documentation for Omnia


#1

Hell!

Where to find actual documentation for Onmia?
Pin outs, console UART speed and etc.

There is one undocumented 5 pin connector near Eth transformers and one 4 pin on left top.
Also i’m unable to connect to debug console - may be RX and TX pins swapped…


#2

Giving this one a bump. I’m also interested in where to connect a serial console.


#3

I had to dig through the schematics PDF since I didn’t find it anywhere else.
CN10 (four pin header next to the LEDs) is, in order from farthest to closest to the LEDs:

+3V3, UART0_RXD_D, UART0_TXD_D, GND

So hook up your TX to pin 2, RX to pin 3, and ground to pin 4. I was able to connect with 115200 8n1 no flow control.

Thank you this works, can connect via minicom. With putty there is some character noise.
