New board on marlin 2.0

Hello,
i am trying to add a new board in marlin (ATmega2560) but i can’t seem to even compile it. i start clean from bugfix-2.0.x branch and then i do exactly what the documentation says:

“Once your pins file is ready, simply add a new define to the boards.h file and a conditional include to pins.h . And you’re done!”

the error i get is : #error “Unknown MOTHERBOARD value set in Configuration.h”

please find attached the files that i have modified.

Of course the clean version compiles fine.
Do i have to add my board in some other background files too?

thank you

I've never done that, but how does Marlin know what pins file to use?

“Once your pins file is ready,.............."
How did yo make your pins file ready?

" simply add a new define to the boards.h file and a conditional include to pins.h"

                                                                 ^^^^^^
                                                                 ||||||

eg in pins.h is

#elif MB(RAMPS_14_EFB )
  #include "ramps/pins_RAMPS.h"                 // ATmega1280, ATmega2560                 env:mega1280 env:mega2560

note you do not use the BOARD_ prefix in the test, the macro MB does that for you.
also note the comments are required. they are for the auto build feature. What options to display and the env to use when building it.

so your would look a little like

#elif MB(TENLOG_D3P)
  #include "ramps/pins_TENLOG_D3P.h"                 // ATmega2560                 env:mega2560

Configuration.h and boards.h look good, just need to add it to pins.h and of course create the pins_TENLOG_D3P.h file that pins.h loads

I was trying to help them figure out why it did not work with my question, as they did not upload a pins file.
from what I found it appears that their board has the same I/O as a Ramps board, so the conditional include would include pins_RAMPS.h and there is no need for another pins file.

Thank a lot,
the problem was that in the pins.h file i was using the complete name of the board..

thanks for the update
