Which LED sample is that? I assume one of the examples in rtems-examples? https://git.rtems.org/rtems-examples/tree/led If yes: The samples in that directory only implements the LED for some boards. It defaults to just printing "LED ON" and "LED_OFF" for all other boards. If you take a look at https://git.rtems.org/rtems-examples/tree/led/led.h stm32f4 has an implementation. But stm32h7 does not. So maybe take a look at the console output whether "LED ON" and "LED OFF" is printed.
