I did some modifications to the pru_speak.c to correct errors until it finally compiled.
Now the problem is that the directory /sys/class/misc/pru_speak/ is not created and the "build/bdist.linux-armv7l/egg/pru_speak/pruspeak.py", line 20, in __init__ method fails with: IOError: [Errno 2] No such file or directory: '/sys/class/misc/pru_speak/pru_speak_abort' I don't know how to proceed from that. Some googling sugested a misc_register() call, but there are no miscdevice at all at the pru_speak.c. Any help?
