Subject: [Xenomai-help] rt_misc_get_io_region()
Date: Tue, 12 Dec 2006 08:38:41 +0100 [thread overview]
Message-ID: <457E5C81.3060006@domain.hid> (raw)
We want to write a Xenomai application that can access the
GPIO pins of our ARM-Prozessor (PXA-270). To get the memory
region I found the function rt_misc_get_io_region(). Unfortunately
there is no discription of this function in the API documentation.
Does this function work like request_mem_region()?
After the call of the rt_misc_get_io_region() fuction it is also
necessary to call the ioremap() function?
Please can you give me a little example, how you can map and access
memory in Xenomai?
I think that is a topic that is interessting for a lot of people.
Regards
Niklaus Burren
