STM32F469-DISCO revision confusion

[PGroe.2]

Hi

I own a STM32F469-Discovery Board bought in 2021. There seem to be (at least) two revisions of that board, "B" & "C" and maybe "A".

Under "CAD Resources" are just schematics for Revision "B" and "C".

If I try to run the supplied example for that board, for example "LCD_DSI_VideoMode_SingleBuffer" I have to choose correct Revision in the code.

Revision "B" seems to work good, "A" not so perfect (flickering) and "C" totally scrambled display... So I assume that I have Revision "B" board.

But if I now look into the schematic of board revision "B" I see there is SDRAM "MICRON MT48LC4M32B2B5-6A" installed. But if I inspect my board there is clearly a "ISSI IS42S32400F" BGA chip installed. In the schematic of revision "C" instead is drawn the same "ISSI IS42S32400F".

Now I am confused.

Can you please enlighten me?

Hello @PGroe.2​ ,

Thanks for pointing out this confusion with the STM32F469-DISCO revisions.

Can you please share the stickers pictures on the boards ?

In this way I can have the batch and revision, and I'll check it out and come back to you with an answer.

if possible, can you upload picture of other side as well ?

So this is a revision B-03 PCB.

Assembled W37 2020.

Please use rev B schematic.

Probably the SDRAM reference has been swapped for availability reason.

I am also current use that board. 
It not working when I use USE_STM32469I_DISCO_REVB but working when I define USE_STM32469I_DISCO_REVA
So does my board is REVB or REVC ?
