Even setting USART3 it doesn't work (see attachments). Did I make a mistake setting some parameters, or is something missing? Thanks a lot

@SofLit  This is another case where the Hardware block diagram (Fig 2) in the UM could be more helpful:

Already mentioned in the User manual of the board:

Is this a new board?

Because older revisions (B01) of it did not have the VCP capability.

Revision should be displayed on a sticker on the bottom of the board.

Yes, but it would be more helpful if it were also shown in the block diagram.

I guess that's why it's not shown on the block diagram - it was just copied without being updated?
