Arduino for STM32

Well, the Arduino GIGA R1 Wifi board has a hardware bug. The load capacitors were not mounted on two of the boards oscillators, 32.768kHz and the 16MHz. Why they did this I have no idea. So, I am left with the contemplation of trying to hand solder in the 1005-size caps.

Thank you so much for the kind responses once more, this seems the place to be then.

I think need just break the ice with this GIGA board and flash a new core and try out the STM32RTC library as suggested. Further information shared above meshes real well with the background readings I've been ...

Thank you for your kind reply.

Yes, the BDCR is write-protected and that is disabled with setting the DBP in PWR reg, IIRC. I kinda get most of what I have been reading. Have not quite gotten to making register changes in my code, not something the casual Arduino user is familiar with. Hence my ...

Hello -

I have an Arduino GIGA R1 that is chipped with an STM32H747 (RM0399 linked here) , and use the Arduino IDE to work with the board. There is an in-chip RTC, complemented by a 32.768kHz crystal across PC14 and PC15, for the LSE clock source. However, I believe the RTC is defaulting to the LSI ...
