OMAP L137 access to PWM registers from Linux

Gary Marks
Prodigy 10 points


I want to access the OMAP L137 PWM registers from an executable running in Linux .  Is there a driver(s) and/or example code?

Alternatively, is there a way to access "hard address" registers, in general, from Linux (drivers,  example code, etc.)?

       devmem2 utility can be used to test the hardware registers. Download the devmem2.c file from any website and compile it for you platform.
