What's state of i.MX6SDL GPIO before system init? is tri-state? is not sure? thanks~
Hello Jinshan Chen,
You may find the Out of Reset conditions of pins on Table 96 of the i.MX6S/DL Datasheet.

Most pins have the same before and after reset values, except for the signals in table 97.
I hope this helps!
