need to read BOOT0 pin on STM32H725

I have designed a set of boards for a client with one USB interface to the main controller.  We can bootload it by the usual methods, and bootload the CPUs on the other boards by pass-thru from the main controller.  I send coded messages to the main ...

Resolved! STM32H7A3 LPUART and BDMA

I'm trying to get the LPUART working with BDMA on a STM32H7A3 MCU.  Eventually I'd like to set it up so the MCU goes into a low power state and wakes up when it receives a LF character match in the incoming message, but for now I'm just trying to get...

Resolved! How to set up IRAM1/IRAM2 in Keil with STM32H742VIT6?

Hello,I'm having weird problems with code crashing, perhaps related to how I have IRAM1/IRAM2 set up in my project:Looking in the reference manual, I see that the SRAM starting at 0x2000_0000 is the DTCM_RAM on TCM interface (data RAM?), the SRAM sta...
