Sorry, what I said before was for i.MX6 series processors. For i.MX7, these criteria are as follows.

- 1ms after the VDD_SOC_IN supply is valid

- 4ms after the NVCC_GPIOx supply is valid

Best Regards,

Artur

The Note you're referring to is applicable to the PD/PU column as well.

This is also applicable to the Power-On Reset state when both following conditions are met:

• 4ms after the external power supply VDDHIGH_IN is valid
• 1ms after the VDD_SOC_CAP supply is valid

except of the LCD1_DATA[19:00] pads that operate as the boot configuration signals.

Best Regards,
Artur

Hello,Community

Which names do VDDHIGH_IN and VDD_SOC_CAP correspond to in Figure 5-9. Power Diagram of i.MX 7 Dual Applications Processor Reference Manual?


What are the pin states in Table 99 in the i.MX 7 Dual Family of Applications Processors Datasheet until the following conditions are satisfied?
• 4ms after the external power supply VDDHIGH_IN is valid
• 1ms after the VDD_SOC_CAP supply is valid
