Hello.

I want to check about i.MX6Q.

Thank you to answer the following questions.

 

We have created a custom board of i.MX6Q.

I confirmed the voltage drop in VDDSOC_CAP at startup.

I attach the measured waveform. (VDDSOC_CAP : No load)

 

CH1:5V(Power-supply voltage)

CH2:2.5V(VDDHIGH_CAP)

CH3:1.1V(VDDSOC_CAP)

CH4:POR_B

Is there a way to avoid the voltage drop of VDDSOC_CAP ?

In addition, the voltage drop of VDDSOC_CAP was Would no issue ?

 

Start-up failure has occurred on the SATA boot.

Believes that the above reason.

(For reset release timing occurred voltage drop of VDDSOC_CAP.)

 

 

Regards,
