How to enable the device registration on Olimex-STM32-E407. #5
Description
To develop Apps with Nuttx it's very important to respect the POSIX architecture. In Nuttx the peripheral device are threated like file, that you must open, close, write, read...(Like in Linux). So to respect this kind of architecture, you must to register all the sensors, communication or whatever you want to use.
But with some board there are a problem, that don't allow you to register the device. The solution is quite simple:
In the menuconfig, go to:
RTOS Features-> Files and I/O -> Maximum number of file descriptors per task-> change the value to 20
RTOS Features-> Files and I/O -> Maximum number of FILE streams-> change the value to 20
Another thing it's to respect the register path when you try to register it. It should be /dev/whatever.
