Hi I'm fairly new to embedded linux development and I've been stuck on this problem for quite some time so any help would be greatly appreciated.
I am using a BeagleBoneBlack Wireless with Ubuntu 18.04 and Linux Kernel 4.14.108-ti-r113. i need to reconfigure the pins that are not by default gpio. For example P8_46 pin which is by default an LCD_Data pin. When using the BBB with a debian stretch image I can use those pins as gpio. However, when I use my ubuntu distro, those pins will not work as gpio. When I try and reconfigure the pins using the config-pin utility I get this error: P8_46 pinmux file not found! bash: /sys/devices/platform/ocp/ocp*P8_46_pinmux/state: No such file or directory Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P8_46_pinmux/state I have tried following numerous tutorials online with no luck. I have looked into using device tree overlays but I always get stuck because there is no slots file in this path: /sys/devices/platform/bone_capemgr/slots This slots file doesn't exist and so I can never proceed. Note: I need to be running the ubuntu distro. Please help.
