I’d like to change pins muxing setting, save them and let them work correctly after boot.
Now I’ve tried GPIO tool for iMX7, but it allows to change current setting but not to save as Boot-up Settings.
Another way I tried is to change the config block directly on bootloader, but it’s the same as above.
Can change currently but cannot work after reboot.
And I have intended to try rewrite the registries, but not mentioned about iMX7 on Web.
How can I save the GPIO Mux setting and let them work correctly after reboot?
