Colibri iMX7D: using BOOT_CFG pins as GPIO Inputs

We’re developing custom carrier board with many GPIOs.
As We understand it, the eFuses are set on the Colibri iMX7D to boot from eMMC/Nand only (during normal boot).
Can We use BOOT_CFG[0…19] pins as GPIO inputs during boot?
Will the boot order changed if some of BOOT_CFG pins are pulled up/down after power on?

Greetings @evan011!

Yes, the efuses on the module are set to always boot from eMMC or NAND.

What exactly are you trying to achieve? You can surely use those BOOT_CFG pins. In fact, most of them are assigned for the LCD data bits on the device tree.

Regardless if you use those pins on U-Boot or on Linux, this should be safe since the module will already be booted by that time.
