FS26 Wake1 pin is shorted supply

[mogilipuri_harish]

hello team,

we are using FS26 SBC in our design. 

1. what will happen if wake pin shorted to 5V or 12V supply??

2. what will happen if wake pin makes continuously high??(we set wake pin polarity as 1 detected wake signal activated)

hi,

thanks for quick replay....

1.how we will know whether FS26 is in DFS and standby mode?

2. what are pins are active when DFS and standby mode? 

3. is it possible to get the status from GPIO weather SBC in DFS state or standby mode?

4. what will happened when wake 1 & 2 pins are shorted GND?

5. for wakeup the SBC we need to connect wake 1 & 2 pins or either 1 pin is ok?

[gw]Different regulators status with different modes.

2. what are pins are active when DFS and standby mode? 

[gw]above answer1.

3. is it possible to get the status from GPIO weather SBC in DFS state or standby mode?

[gw]No

4:what will happened when wake 1 & 2 pins are shorted GND?

[gw]wake up function depends on the setting below:

5. for wakeup the SBC we need to connect wake 1 & 2 pins or either 1 pin is ok?

[gw]Please see wake conditions:

From this below internal diagram of WAKE pins, I think no problem for short to 5V or 12V but should more current consumption.
