imx7d power on sequence issue

[justin_hsieh]

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

Our PCBA

Thanks,

No, this initial voltage pulse of VLDO3V3 seems not to affect the system operation and reliability.

Best Regards,
Artur
