Hello,My STM32L476RG Nucleo board does not read out the RTC time after i updated cube IDE to 1.17When calling "HAL_RTC_GetTime" the subtask in "stm32l4xx_hal_rtc.c" sTime->Hours = (uint8_t)((tmpreg & RTC_TR_HT|RTC_TR_HU))>>RTC_TR_HU_Pos); the current...

I found the solution: https://community.st.com/t5/stm32-mcus-products/rtc-isn-t-updating-time-in-free-running-mode/td-p/648713 The shadow registers seems to be the problem, i do not know exactly why but i had to enable bypassing with: HAL_RTCEx_Enabl...

I did now a complete reinstallation of Cube IDE with 1.17 and made a new project with the copied main.c to test the RTC. It has still the same problem. The MCU does not refresh the sTime variables when running. What is the difference when i am openin...

Both projects are not working. Also if i do a new from scratch in 1.17. Is there a problem with the libraries maybe during the update?

It was 1.13, but i did a new project with 1.17 to check that it is not a problem from the previous written project.

Yes, until we build a Class D amplifier with a easy to handle via Software DSP ADAU1401, but Analog Devices did not support class D PWM audio output. So we whant to try STM32 for a Class D active speaker. And we see that there is no easy to handle so...
