I’d like to change a GPIO pin’s internal pull-down to internal pull-up.
The GPIO pin is GPIO17_MDM2AP_READY. This pin is internal pull up on TX1, but it is changed to internal pull down as a default on TX2.
So, I refered to the chapter “TX2 Configuring Pinmux GPIO and PAD” in the document “NVIDIA Tegra Linux Driver Package Development Guide 28.1 Release”. According to this document, I created dtsi files, converted to cfg files, and placed them to /bootloader/t186ref/BCT on the host PC. Placed files are following.
As next step, what should I do to reflect this changed to TX2?
