I choose "SABRE Board for Smart Devices Based" as my reference design.<BR />I have checked the Power supply page (Page19) , PMIC part number that is used is MMPF0100F0AEP. I checked the PMIC datasheet and it has pre-programmed with F0 configuration. There is a table in the SABRE Board PMIC schematic about power-up sequence that it is not match with F0 configuration. I have two questions:<BR /> <BR />1. Does the "SABRE Board for Smart Devices Based" use another configuation?<BR />2.Is the desin file last update of the board ?<BR />3.In the power-up sequence of datasheet of CUP ( MCIMX6Q6AVT10AD) is recommended to VDD_SNVS_IN supply must be turned ON before any other power supply. It may be connected (shorted) with VDD_HIGH_IN before VDD_ARM_CAP, VDD_SOC_CAP but in SABRE Board VDD_ARM_CAP and VDD_SOC_CAP will turn on before VDD_HIGH_IN that is not make sense. <BR />Please advice me that shall I do ?</P></BODY></HTML> Thu, 12 Sep 2019 06:43:04 GMT calibronic 2019-09-12T06:43:04Z SABRE Board Power-Up Sequence https://community.nxp.com/t5/i-MX-Processors/SABRE-Board-Power-Up-Sequence/m-p/916011#M137887 <HTML><HEAD></HEAD><BODY><P>Hi dear all.</P><P>I am going to design a custom board base on i.Mx6Q processor.
