Omega2S+ SW_RST Clarification?
-
Hello, I have a small question probably obivous but I want to make sure.
Datasheet says SW_RST is used to reset operating system and it's active high.
This schematic if from Reference Schematics document.
As far as I know these tact switches connects 1-2 and 3-4 when pressed and 1-3, 2-4 does not connect on default but in that case schematic looks weird.
In short my question is if I want nothing to do with SW_RST pin can i leave it floating or do i need to pull it down?

@akif-durmaz The Omega2 datasheet provides details of the required status of pins in order to boot. The rest is up to you.

Just to add on, you should tie it to ground if you are not planning on using it. However, it is worthwhile to note that this pin is quite important when trying to do serial recovery procedure or manual flash using usb as you need to hold this button on power up.
Always good practice to at least have provisions for a jumper or something if the need arises.
