Click the down arrow on the right side of the Timebase Source selection box and choose a new one. You will need to enable the corresponding timer first.

If that doesn't work, attach your IOC file.

Go into TIM6 and assign the timer to the CM7 core.

Go back into SYS and select TIM6 as the time base.

you need to choose which equipment will be used by which core. In your scenario, you need to choose from the timer configurations that timer6 will work with Cortex-M7. If you activate the timer, you cannot select the timebase source.
