There are two different H743ZI boards, make sure you're building for the right one, check the command line define passed to the linker, and then at the #ifdef's in the include file with LED2 etc in it.

​Thank you, Clive1!

I only got one schematics, it doesn't match my board.

Do you know where I can find MB1137 Rev B schematics?
