Hello!
So I'm trying to test the Linux User Mode Pseudo Driver
http://www.wiki.xilinx.com/Linux+User+Mode+Pseudo+Driver
Problem is
1) SDK cannot find the close() function at the end (Implicit Declaration warning). I found open() resides in fcntl.h, but there is no close() in this file...
2) Even before coming to the end, the program crashes when trying to access the freshly mapped area. I am trying to use the code with the existing LED-module (commented out the data direction part), do I need to unload the existing driver for it to work or something? How?
Thanks in advance!
