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 _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
