Hi Vinicius. Some minutes ago I was able to make it work. I tried to compile a custom firmware, flash it to pru (through remoteproc) and start it, and I've got success innchange state value.
However, I'm not able to control (on/off) a LED in BeagleBone Green Wireless. I've set in config_pin the gpio P9_27 to pruout successfully, but I've got no lucky in controlling the LED I've wired to this gpio. I'll try to do it in BeagleBone Black, and I'll follow pru cook book as you recommended. Thanks!
