Hello All, I am using the Internal RTC of STM32F767 MCU. The VBAT pin is connected to an External 3.3V Coin Cell Battery At Power ON (Debug window on STM32 Cube IDE), before HAL_INIT when i see the value of RTC BKP1R Register it is 0x5432 as I intend...

I used a Nucleo F767ZI dev board to check and write firmware(The IC on the board is STM32F767ZIT6U with the other characters being AA 254 VQ Z on first line and TWN AA 341 on line 2),when I use HSI clock I am able to operate PD7, PG9, PG10, PG11, PG1...

After the VDDSDMMC being connected, all pins work as intended. This was the errorVSS is internally connected as I verified in the Layout as well as the Hardware. Thank you for your help @Chris21 @Andrew Neil @LCE @Richard Li

Hello, you are right, but the KiCAD symbol just gave one VSS(and somewhere on the web it mentioned it's all internally connected)Nonetheless, let me check on the hardware if all VSS pins are actually connected to GND or not.

Hello @Chris21, all 10 pins are connected at the top of the MCU and then given to a single VDD supply, isn't it correct?

Sure, I will try this out in the office in another 10 hours and see what the result. Most likely this should be it. Thank you for pointing this out. Regards,Akash Rao
