Hi Robert, Thank you for the explanation! Is it about internal cache? Looking at https://www.st.com/en/microcontrollers-microprocessors/stm32h7-series.html I can see that H723/5 shares mostly everything with H333/5. I only tested NuttX on STM32H743ZI and STM32H753BI (I and Jorge added support to this few weeks ago).
Please take a look at Jorge's PRs, probably if you fix the memory in the linker script and the clock tree for your board NuttX will work fine on it.
