Hi 小辉哥 в

on Sabre schematic spf-27392  p.19 "AUTO ON" feature is used, to turn it off

it is necessary to implement  "Optional : PMIC Power ON circuit"

hi,igor,

I'm sorry, I forgot to use processor, I use a imx6ul, not imx6Quad, Schematic is also reference imx6ul  - EVK

please check that you have valid coincell connected

thanks, i have valid coincell connected, found the reason is caused by the reset chip, I use a UM811, UM805RE instead.
