MPC5644A System Timer Module problem

This post is related to the previuos one MPC5644A System Timer Module problem.

@ David:

Thank you so much for your answer, I tried the solution you proposed and worked ok!

I miss understood what was stated in the  Reference manual that the Sytem Timer Module counter roll over automatically from 0xFFFFFFFF to 0x00000000 and so I thought that every time one comparator is equal to the counter an interrupt is raised...

moreover I just tried to use the PIT with success, the purpose to use this timer is to have a basic tick counter for a scheduler and I thought the best way was using the STM..anyway, I think I will use the PIT.

Thank you again,

have a good day.
