I am a student making a custom system on a PCB with the imx23 processor. I left my PSWITCH pin as no connect. But i read that it should be pulled to VDD in order for the system to boot up, did i read that right? i read the power-up part in the manual and it lists either a 5V power supply or PSWITCH pull to above 1 v for 100 ms. So do i need to connect PSWITCH to anything?
I have attach my .sch and .brd file, please comment, feeback for improvement greatly appreciated. The files are attached.
problem i faced so far:
1. processor not booting up, 2.5v rail reads 5v,
what is one way to check if processor boot correctly? attached a PC to the USB pins to see if there are any output? or put a serial console on the USB Debug pins?
