Dear Olimex

I am planning to use the excellent A20_SOM and wishing to be able to power it up and reset by external means.
It seems that the right signals to use are AXP_PWRON and AXP_RST as detailed in the schematics
https://github.com/OLIMEX/SOM/tree/master/A20/A20-SOM

However, when I download the header connector from
https://github.com/OLIMEX/SOM/tree/master/A20/A20-SOM/KiCAD%20connector%20library

I cannot find any reference of AXP_PWRON

Question: What am I missing ?

Thanks

ok, I found what I am missing...

The footprint in github is not complete, you need to look to A20_som_dimensions.png to discover the
position of GPIO-6 where the extra pins are wired

Hello dear OLIMEX

I have updated the KICAD footprint for A20-SOM and I would be very grateful if you could confirm that it is good.

Obviously, feel free to use any way you wish, I do not claim any right whatsoever on it..

Thanks

I have managed to actually make a PCB and mount an A20 board on it and the footprint fits well.
