Description

I have added a new board based on balckpill(Stm32f401cdu6). For further information you can check this issue 25136

There is no need to create a new MOTHERBOARD entry to compile Marlin for custom board.
You can use #define MOTHERBOARD BOARD_CUSTOM and put you pins definition into "pins_custom.h" file.

There is no need to create a new MOTHERBOARD entry to compile Marlin for custom board.

The main question is this a one-off custom board or something that will be mass produced/widely available?

Or even if opene sourced, so is a possibility of more than one

[arslan437]

This stm32board is widely available someone like me might use this one in future.
@ellensp have share the link(https://reprap.org/forum/read.php?415,889516,889539#msg-889539) that someone did tried to build the firmware for this controller also.

@arslan437, blackpill boards are used for in 3D printers in various different projects for quite some time.
Shields they are used with have different pinouts, so you can't have them all in one universal pins file.

@jmz52 Thanks for Sharing the links.

If something is not standardized than you will find lots of different variant.

I think if we create a official board for blackpill in Marlin than most people will use that in future Instead to creating there own version. I have add that to Marlin because there was, not one there. If it was there I would have used it any.

any updates on this ?

[jmz52]

There are three versions of blackpill boards and all of them are supported by ststm32 platform:

• blackpill_f401cc
• blackpill_f401ce
• blackpill_f411ce

File buildroot/share/PlatformIO/boards/marlin_custom_blackpill.json is irrelevant - it is a copy of file that is already available.
Also your file is only applicable to one version of blackpill.
PlatformIO environment definition for blackpill requires only these three lines

[env:custom]
extends                     = common_stm32
board                       = blackpill_f401cc
