OMAP3530 General Purpose Timers

Other Parts Discussed in Thread: OMAP3530, AM3517

Has anyone tried using the OMAP3530 general purpose timer via linux?

 

I have written a simple test kernel driver that is referencing the:

omap_dm_timer functions. 

But the build complains:

WARNING: "omap_dm_timer_stop" [.../hellodrv/hello.ko] undefined!

for all of the omap functions.

 

Can anyone provide any insight?

    Hello,

    I use the GP timers on the AM3517 with success... Did you include <plat/dmtimer.h>  header in your source file?

    I think I got that message when my code references a function that is not visible to other kernel modules (i.e. their prototype start with static keyword and they are not exported).

    Good luck!
