Hi, as we are not using most of the interfaces on the Apalis T30, is there a simple tool to disable unused interfaces or configure the unused signals by disabling them or enabling the internal pull up/down resistors ?. Aim is to reduce power consumption and improve EMC.
Or is this achieved with a recompile of the kernel… if so, is there any reference material.
Unfortunately, there is no simple tool to disable unused interfaces or enabling the pull up/down resistors. With the newer (mainline) Kernel, there is the possibility to use the device tree files to setup the input/outputs of the module. With the older (downstream) Kernel, you can use the board files for pin muxing and pin setting.
