Our newly designed N4200 board, PMIC uses the TPS65094. After powered up, the PMIC can correctly supply power other than VCC_VCGI.
The signal of the N4200 reading bios only lasted for about 150us, and then stopped, no VCC_VCGI setting and PLTRST de-asserted. This problem occurs because the power supply is not good, or the strap configuration is wrong. What suggestions do you have?
