Hello, I am trying to communicate with the PRU unit on a *Debian 9.2* and kernel *4.9.54-ti-r68* by Robert Nelson, but the file
*/dev/uio* is not loaded / enabled by default. Looking for **pru** on my file-system I have:

so I understand it has been enabled through device-tree and somehow it can be used. Also, the *uio* kernel module is loaded by default (i can see using *lsmod*) but the */dev/uio* isn't there. How to enable it ? What do I have to do to load it automatically at boot ?
