iMX8M series Power sequence

[sahilnayak]

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,

Any update on this??

[Rita_Wang]

I will confirm it for you.

Hi Rita,

Please confirm the power sequence.

Attached is the image of power topology for more clarification.

Hi Rita,

As we have critical timeline for the design phase, please confirm on the above asap, so we can move forward on it.

Thanks & Regards,

Hi Rita,

Awaiting for your quick response.

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
