Hi, I have created a simple driver to implement mmap and an application program to uses the sys call mmap and tries writ/read data. The mmaped area is the RAM.(I am working on beagle board) This works fine when I execute my application program through the shell/console but fails (with the following error) to work when executed through an apk.
