Hello everybody,i have a problem with the RTC Calib Out (1Hz) on PB2 and TimeStamp Input PC13 (Board: NUCLEO-L4R5ZI).PPS (1 Hz clock) should be on PB2 (RTC_Calib_Out) for time synchronization with other chips.PC13 should be configured as TimeStamp In...

Hi,what happens when the CPU enters the default bootloader?AN2606 lists all peripheral units that are always re-initialized (e.g. UART, SPI, I2C, ..)What happens to the other ports and GPIOs (e.g. Port E/F/G)? Are all GPIOs reset or do they keep thei...

Yes i set the RTC registers as in case 2.The input signal is always a 1 Hz clock with amplitude 3.3 V.The amplitude changes when COE bit set. If this bit isn't set, then the PC13 works as expected as normal gpio exti or as RTC_TS (see case 1). Always...

Same as in case 2

@Community member I have assigned PB2 with RTC_Caliboutput and PC13 as exti input with rising edge.PC13 cannot be used. The input signal is always 1.4 V.

I wanted to use the RTC_TS for time synchronization because a rising edge triggers an interrupt and at the same time the current time is transferred to the TS register.With the timestamp I would know how many sub-seconds the RTC of the L4 deviates an...

Thank you, @Community member .Here is the complete code generated from the CubeMx.
