Timer2 with Fsysclock

I use the timer 2 with the frequency from the XTAL and it works well. Then I tried to use this timer with the frequency from System clock (with the PLL) to have a greater frequency, but it doesn’t work.
I put TCLK to 1 in the timer control register, I accorded the reload value. I checked in “bsp.h” that BSP_CLOCK_SOURCE was set to SELECT_THE_CRYSTAL_OSCILLATOR_INPUT.
Anyone has an idea?

Sorry, made a mistake. It works well…
