Pin No. 4 in GPIO 4 connector is mentioned as GND in the A20 SOM user manual. Whereas in the A20 datasheet pdf it is mentioned as LDO3_2.8V. So what is Pin 4????  :-\ :-\ :-\ :-\

I see it as GND but where exactly are you looking when you think it's not?

(I couldn't even find LDO3_2.8V in datasheet.)

You can be pretty sure it's GND I reckon.

Thanks John. Sorry I meant A20 SOM schematic pdf. This is the link of the A20 SOM schematic pdf

https://www.olimex.com/Products/SOM/A20/A20-SOM/resources/A20-SOM_schematic.pdf

Please see pin no 4 of GPIO-4 connector. It says LDO3_2.8V.  :)

No wonder I couldn't find it!

I'd email support but be sure to say the right docs and which parts :)
