Hi All,
I am trying to config the pins in beagle bone linux kernel 3.8 through a command “config-pin p8.11 gpio” but it gives as follows:
P8_11 pinmux file not found!
cape-universala overlay not found.
run “config-pin overlay cape-universala” to load the cape.
But when I ran “config-pin overlay cape-universala” command it gave error as:
“failed to load firmware cape-universala-00A0.dtbo
Error loading device tree overlay file:cape-universala”.
I request everyone to please help me to resolve the issue.
Thanks and regards,
Imran.

To enable pinmux configuration in the BeagleBone Linux kernel 3.8, you typically need to modify the device tree or use the config-pin utility. Here’s a general process:

  1. Device Tree Modifications: Update the appropriate device tree overlay file to configure the pins for your application.
  2. Configuring Pins via config-pin: You can also use the config-pin utility to set specific pins to input, output, or other functions directly.
  3. Rebuild the Kernel: If you are using custom configurations, rebuild the kernel with the updated device tree.

Check the official BeagleBone documentation for detailed steps and examples specific to your setup.
