Hello,
I need to configure the following pins with internal pullup resistors.
Ixora GPIO 4 (X27 pin 16, MMX3 pin 7)
Ixora GPIO 5 (X27 pin 17, MMX3 pin 11)
Please suggest me how to configure.
Note: I am using Buildroot build system to customize the kernel
Hi @mohi and Welcome to the Toradex Community!
Could you provide the version of the Hardware and Software of your module?
Best regards,

hi @mohi
You need to change the devicetree and compile a custom devicetree as explained here resp. here .
This documentation will explain how to setup the Pad register for Pull up and Pulldown resistors.
To know which SODIMM pin belongs to which PAD, please check the section 4.4 of the Datasheet .
Best regards,
Jaski
