We designed a number of carrier boards for TX1 and TX2 modules before. Now, we are working on a carrier board design for Xavier modules. We will have a carrier board without any power button mechanism so the board will be powered on by an adapter and we want the board to power on without need of a power button. We did this mechanism easily on TX1/2 modules easily before but same mechanism for Xavier boards seem a bit complicated when we look at schematics and OEM design guide.
So, to achieve this mechanism for Xavier modules without an MCU, how can we implement power button circuitry? I guess we must use SRC0CS25D chip. We dont need power-off sequence in the board. The guide says we need to connect ACOK signal to ground but we dont have this signal in our design. In carrier board schematics this signal is just connected to MCU pins but there is no connection in SRC0CS25D chip.
So, how we will achieve this functionality with SRC0CS25D chip?
