PSWITCH pin questtion imx233, with PNG picture of brd
« on: February 05, 2019, 04:33:32 AM »
Hello all,

 I have an issue where my custom imx23 board did not boot correctly. I read in the tech manual of the imx23 and it says that the custom system has to have a way to pull PSWITCH to VDD...in order to boot. But i also read that as long as it detects the "5V true" , then it should boot fine. As it is, i have the PSWITCH pin as a no connect...should i incorporate how olimex did the maxi board, where they tie PSWITCH to 3VIO, or ground, using the power switch....should i just do exactly that?

I have attached my schematic and board lay out, on my google drive, it is a ,sch and .brd file drawn in EAGLE, please comment! feedback greatly appreciated.
