Dear team,

 

My customer is developing their board with i.MX6SoloLite, and they are facing the issue about start-up.

What they want to is;

- Using switch connected to ONOFF pin of i.MX6.

- When the first time VDD_SNVS_IN has been fed, PMIC_ON_REQ stays in L.

- When the switch is pushed -> PMIC_ON_REQ outputs H -> PMIC start the power-on sequence.

Against the above, the actual behavior is as below.

When the first time VDD_SNVS_IN had been fed -> PMIC_ON_REQ outputs H -> PMIC starts the power-on sequence.

 

I think the above behavior is the specification of i.MX6SL, but

 

Do you have any ideas to realize the customer’s requirement?

 

Thanks,

Miyamoto
