[Resend] SHIELD (tegra114-roth) Serial Console UART

[Marcel Ziswiler]

Hi there

Does by any chance anybody know how one can get a serial console UART on SHIELD (tegra114-roth)? I know there is some kind of a debug connector inside [1] similar to e.g. the one found on Cardhu albeit not assembled of course but is that pinout standardized?

I remember the actual debug pads being on the bottom side of the board 
on the right side of the SoC (i.e., right of the green rectangle on your 
picture). If you go that way, someone @nvidia.com can probably look up 
the UART pads for you. However, another way (that I used briefly) is to 
grab one of these:

and with some pinmux editing get a 3V3 serial port out of the microSD slot.

Cheers,
Mikko

Actually, I am tired and confused about the orientation of things; but 
anyway on the bottom side, which makes access difficult.

The pinout should be identical to Cardhu ; otherwise, as Mikko
suggested getting a serial out of the SD port after some pinmuxing
would achieve almost the same result with less tampering.

PS: nice to see people are actually using that SHIELD port! ;)
