TouchGFX configuration not reflecting STM32H743I-EVAL board schematics

[Southbranch]

We are considering a custom PCB design similar to the STM32H743I-EVAL.

However, we just discovered that when creating a TouchGFX project for this board, many configured pins are set different (shown in STM32CubeMX) than given on these schematics:

A few examples of signales routed to other pins for the SDRAM: SDNWE,SDNE1, SDCEK1. There are also a handful of pins for the LCD which are routed elsewhere. The TouchGFX project runs fine so obviously these schematics must be invalid..

Is there a newer schematic version than MB1246-E02 dated in 2019?

Many thanks in advance

There have been several versions of the board what one do you actually have?

The Rev E is EVAL2, with the ST-LINK/V3

The board has STLINKV3 and the printed label on the MCU board says: MB1246-H743XI-E02, which should indicate it has the second schematic in my post. The display board says MB1063 REV B.

However, I can't find any other schematics than listed above

Right, but that's their prerogative, you might have to talk to an FAE to get others.

You might want to cross check the BGA ball assignments, I recall there being some subtle changes in a handful of them over the development cycle for the H7's which spanned back to 2017

Also the EVAL boards tend to have a myriad of solder-bridge and resistor paths to remap or reconfigure board use cases.
