Has anyone used the Pin Mux Utility? I'm trying to enable R30 and R31 on
my PRUs. I've had a rough time enabling device trees so I decided to try
and use the Pin Mux Utility. It seems relatively easy to use and it
produces nice .h files but the compiler has an issue with some of the code.
#define MUX_VAL(OFFSET,VALUE)\
writel((VALUE), AM335X_CTRL_BASE + (OFFSET));
Neither GCC or G++ know what to make of writel(). They say it's not
defined and such. I've read something about linux/io.h but I haven't been
able to find it. Am I barking up a tree with this utility?
Those who have successfully done Pin Muxing, by what means? I've tried
doing the hipster circuit tutorial but debian doesn't like the tree so says
dmesg. I'm not sold on the tree method anyways because I wouldn't mind
being able to alter the muxing between compiles not restarts.
