Carrier board power on circuit without MCU

Hi Team
We are making costume carrier board for Xvaier NX . We are e not planning to use MCU in our design. Do we need to take care of any timing requirements. Kindly suggest how we should modify reference design if we don’t want to USE MCU.

Hi, there is a power up sequence in product design, that is for power on system. The key point is to assert POWER_EN after system power supply is stable, and enable carrier board power rails after SYS_RESET released.

HI Trumany
We are considering putting the nano power up section in Nx design to replace MCU. Do you think any specific consideration I need to take care.

Sure, they are compatible.
