If you look in the 2.6 kernel source at :

arch/m68knommu/platform/5307/pit.c

Which has moved to:

  arch/m68knommu/platform/coldfire/pit.c

in modern versions of 2.6 kernels.

you will see an example of setting up PIT1 in the function coldfire_pit_init.

On a Coldfire 5233/5235/5307, you can use one of the programmable interrupt timers to get a 10ms interval. This is a less evil solution than using the timer tick. I don't know if all Coldfire processors have more than one PIT though since I am by no means a Coldfire expert. Note that on at least the 5233/5235/5307 ucLinux ports, PIT1 is already in use as the timer tick. I personally use PIT2 for a 5ms timer needed for one specific protocol without having to resort to the real time extensions.

Hello John

Thanks. I'm using an SSV board with 5282 CPU. I'll check the docs on the timer.

Are you aware of any code examples? _______________________________________________
