Hello all,


I start the clock for the GPT by writing the bits 20-23 in CCM_CCGR1.

Set the prescaler register to 0, reset the GPT, writing 1<<15 to the control register, waiting until (1<<15) is 0.


Writing 1<<18 + 1<<16 + 1<<9 + 4<<6 + 1

capture on rising edge

restart mode

low frequency clock



The counter register, 0x02098024, stays 0, so the status register.


Did I forgot something?


Many thanks for your help.
