Hi,
I need to switch the state of the pin mux for a certain pin at run time, preferably from a user space application. I tried mmap'ing the control module register for the pin as explained in section 9.3.51 of the TRM but without success. The register acts as though it is read only even though the TRM says that it is read/write.
Is there another way to do this? Is there perhaps a kernel driver function that can be called to accomplish this? Or am I missing a configuration somewhere else that then allows me to change the state of the conf_<module>_pin register?
