How to set up the Low Power Timer LPTMR

Hello

Im trying to set up the LPTMR module since days, but it doesnt work.

I set it up by processor expert. But it seems is not that easy...

I've done the following:

- Enabled the LPTMR clock in the CPU module (CCM_CCRG2 -> CG0[1:0)

- Set up the LPTMR module:

When i start debugging, the counter value of the LPTMR is always 0. What is wrong?

I set the clock 'FIRC' to the clock output pin CK01, the clock runs. So i think the LPTMR_CNR should be upcounting?

I read also the counter value in the software, but there it is also always 0.

Do I have to enable something else?

thanks in advice!
