imx7d power on sequence issue

Question asked by justin hsieh on Jul 15, 2020

Dear Team,

Our Platform is i.MX7D with PF3000 and we find some abnormal signal when we testing the power sequence.

 

When system power on, VLDO3V3 will have abnormal signal then pull high, it seems some current back leakage from somewhere. 

The current back leakage of our PCBA is higher than EVB. will it impact system boot-up or other HW function?

 

i.MX7D EVB

EVB's power on sequence

Our PCBA

Customer's PCBA

Thanks,
