wrong here
see #937 (comment)

and, as i can understand it's not a devboard, but shield for F4Disco
does it really require separate variant defined?

Hi @shchers
I'm agreed with @stas2z, it is a derivative of an existing board.
Yo should better create a library for it like it is done for all the X-Nucleo-Boards.

You can redefine all PinMap arrays as it is weak and define all alias for your pin naming.

Hi @fpistm
Right now it's derivative of STM32F4Disco as fast line to bring new education board for students and scholars.
But the idea is to build new cost effective STM32F407-based board.
Of course, if adding this board will be rejected, so lib or parallel tree will be the single option for us.

@stas2z
Thank you for pointing to your comment in parallel thread. You are absolutely right!
For some reason CCM and RAM was mixed together. It's definitely mistake.
I'll fix it in this patch, but the rest of configs need to be updated also.

With best regards,
Sergey

But the idea is to build new cost effective STM32F407-based board.

In this case it could be added in the Generic F4 menu.
But not while it is a "shield", in that case library is one option or this:

Anyway I guess a library is the easiest way and match to your "shield".

P.S: Iif you need help does not hesitate to ask on the forum.
