Hi All,

I have read a lot of article about Real time kernel on Ubuntu and I would like to change my kernel as Real Time Kernel on my Beagle Bone however I am not convinced that if I use rt kernel can I access gpio, pwm directory and so on. Is there any different between rt kernel and default kernel in fields of gpio,i2c,spic on Beagle Bone. I would like to know that if i change my kernel as Real Time kernel , what will change on my Beagle Bone?

Thanks in Advance
Best Regards,
Eren

There should be no difference, assuming you are willing to access the GPIO, etc. at the register level.
I do all that sort of stuff using mmap to access the registers directly, and that should be no different.
Some of the file-mode access probably would not work the same way. But, those are slow ways
to access these devices anyway.
