IMX7D GPIO on manul reset input of the reset IC

[frankyhsu]

We use GPIO1_IO0 and IO1 as the reset MR input, we know the IO0 is internal pull up but IO1 is internal pull down. Do we have method to let IO1 to be pulled high? It seems there is only IO0 that has internal pulled up. The internal pull down will let reset IC continue to reset.

Hi Franky

out of reset state is described on Table 100. i.MX 7Dual 19 x 19 mm functional

contact assignments i.MX7D Datasheet

and there is no way to change that behaviour immediately after power-up.

Best regards
igor

Could we use pull high on this pin to change the initial status?

[igorpadykov]

in general yes, it can be overriden with external pull resistor.
