It is not possible to set RTC output on Tamper pin for Second and Alarm Pulse.

Hi,

 

I try the whole day with an F103C8 to have the Alarm Pulse on Tamper Pin C13 but it is not possible, I tried with PullUp resistor and also I tried to configure manually the GPIO Pin to AF OD config. But with my Osciloscope I cannot see anything. Only works the Clock divided with 64 output, with this configuration I can see the clock with a 511Hz signal. I tried CubeIDE 1.15 and 1.18 with tha same results.

Any Ideas?

 

Kind regards,

Niko
