Unknown CPU error when selecting Controller board. #6957

Closed emhowland closed 7 years ago

emhowland commented 7 years ago

I have tried copying the proper board from boards.h as well as the old method of "43" but every time I have tried to verify I get the following error.

exit status 1

error "unknown CPU"

I am unable to tell what tab it is coming from. I have gone back to the raw download and I have focused on just selecting the correct board.

define BOARD_RAMPS_14_EFB 43 // RAMPS 1.4 (Power outputs: Hotend, Fan, Bed)

Arduino Mega 2560
Ramps 1.4 115200 Baudrate

I am sure it is something I am overlooking. I am very rusty with this. Have not done anything with my printers in a few years.

Please help.
