LED LD2 on STM32h745ZI-Q Nucleo 144 board not working

[JimSChen.4]

Sorry this is a very simple question but somehow LED LD2 just won't work on STM32h745ZI-Q nucleo 144 boards. As per the manual "UM2408 STM32H7 Nucleo-144 boards", the LD2 is connected to PE1 (by the way, I tried PB7 as well as the older one may on this port). The same routine for other two LD1 (PB0) and LD3 (PB14) all works fine. I have checked the wiring which is also correct. I have two boards all the same. This is nearly a bare bone program just toggling the LED on and off. It just doesn't do the job. Any idea please?

LD2 on PE1 works on the NUCLEO-H755ZI-Q (CRYP+HASH version)

Make sure the clock is suitably enabled. CSI and IO compensation also.

LD2 works just fine on my "NUCLEO-H745ZI-Q" board.

Thanks Clive and TDK for your quick reply and help. NUCLEO_H745ZI_LED works. Indeed I have missed this line __HAL_RCC_GPIOE_CLK_ENABLE() for port E in the init. Now works a treat!
