Hi,
I am currently using i.MX8QM for a circuit design. Encountered an issue: If the POR_B pin of i.MX8QM could be connected to signals other than the RESETBMCU pin of PMIC, such as external buttons. In other words, if the POR_B pin of i.MX8QM could be used as a non power-off reset pin, except for power on reset. That is, the power of i.MX8QM is maintained normally, while internal reset occurs in IMX8QM.
Hello, I hope you are doing well.
From your description I understood that i.MX8QM reset could be activated from different sources but, I do not totally understand your question. Could you please explain me a little bit more?
Best regards.
Hello,
I think your reset design should be feasible. If you are worried about damage your MPU, just keep the power-up/power-down sequence and you should be safe.
Bes regards.
