Hi Team,
We are going to use iMX8M series processor in our application. As per power sequence mentioned in the IMX8MDQLQCEC document, we will power VDD_SOC with external regulator and to power VDD_ARM voltage we will use SW1A/B output of PMIC PF4210. We don't have requirement of GPU/VPU, so to power VDD_GPU/VPU, we will use SW1C output of PMIC. Please confirm if the power sequence is okay.
Regards,
Sahil Nayak
Hi Sahil Nayak ,
Sequence is OK, power topology is important,so if possible, please do not remove the circuit of external regulator for VDD_ARM,just DNP. when the power is OK after validation then remove.
Have a nice day
Best Regards
Rita
