Can't build custom board about nuttx

[fdcavalcanti]

Right, so I got it to compile by reading some issues from make export in #10388
Just had to add CONFIG_ARCH_BOARD_COMMON=y.
I understand that there is a common directory inside boards/stm32f7 but since no defconfig had it, I didn't even think about it before.
I'll keep working on it, try and track down other issues and I'll update the docs.

Thanks everyone.

@fdcavalcanti I just saw that our documentation for custom board is very shallow: https://nuttx.apache.org/docs/latest/guides/customboards.html# we need something like Custom Apps that @TimJTi wrote.

The error means that some Makefile rules or path to create libboard.a is missing.

BTW, if this board is a commercial board (i.e. from ST) then it is better to add it as official board into NuttX mainline.

Hi @acassis. Its not a commercial board. I'm using a Nucleo-144 integrating in a different equipment as a proof of concept. Its just easier for me to version only the board files and use the custom board settings.

@fdcavalcanti - have you tried the instructions to move it completely out-of-tree? It works for me.

@acassis - I "ported" the custom boards stuff from the old Wiki (Confluence?) to the current documentation tree and added a bit to it too if I recall. I will revisit it tomorrow and see if it still holds true or needs enhancement - but it is only for out-of-tree boards. I think there's different documentation somewhere or other for in-tree new boards - I'll look, and see if it needs any work that I can see.

Hello @TimJTi thanks for the input.
Yes I tried. I also applied the modifications in the issue description above.
This is really an issue now because I think porting to a similar board, out-of-tree, should been simple. I need to do this PoC and am stuck in what seems to be a basic issue.

I'll keep trying to figure it out and hopefully I can contribute on fixing and documenting.

Thanks
