Details about some LEDs:

↑ ^1.0 ^1.1 ^1.2 ^1.3 ^1.4 ^1.5 LD2, LD3, LD4, LD5 (MB1936): some user LEDs are used to reflect the system activity, while the others are left free to be used by the application, as explained in LEDs and buttons on STM32 MPU boards article
↑ LD7 (MB1936): flashes green when Ethernet connection established
↑ LD11 (MB1936): turns green if power connection established
↑ LD6 (MB1263): flashes red if ST-LINK/V3-1 connection not established, else green
