error: #error "Board is not defined"

[brianfoshee]

First - thanks for maintaing this repo, it has been incredibly helpful in getting me up and running with gcc tools on OS X. I'm new to bare ARM development and nordic devices so I apologize if I'm asking elementary questions.

I have an nrf51822 evaluation kit, using S110 softdevice version 6.0.0, SDK version 5_1_0_36092, ARM toolchain from here. The following shell variables are defined:

export SDK_PATH=$HOME/Development/nordic/nrf51_sdk_v5_1_0_36092/nrf51822/
export TEMPLATE_PATH=$HOME/Development/nordic/nrf51-pure-gcc-setup/template/
export USE_SOFTDEVICE=s110

I have a couple of questions that I'm hoping you can point me in the right direction to solve, I'm trying to compile the test project blinky_example in the SDK:

• I'm getting a board is not defined error. In boards.h the nrf51822 isn't listed - should I just use the nrf6310 definition?
• After setting BOARD and FAMILY defines in main.c, running make main gives me this:

➜ make main

I noticed that the two -D compiler flags aren't showing anything. Are BOARD and DEVICE supposed to be environment variables in my shell? And do I need anything else in the pure-gcc folder besides the Makefile?

I'm not a contributor of this project, merely a user, so I hope Ole and friends won't mind me responding.

Yes, just use nrf6310 if that's the motherboard your nRF51822 is sitting on.

Don't run 'make main', just 'make' will do.

@eliotstock thanks, that gets me further than I was.

I'm still seeing error: macro names must be identifiers but I believe that is from the blank -D -D flags in the command. In the Makefile those get filled in with BOARD and DEVICE. What should those be set to? My best guess is DEVICE=nRF51822 and BOARD=nrf6310.

When I set BOARD and DEVICE to the values I mentioned above, I see this:

Is that related to what I have those variables set to or is it something else?

[brianfoshee]

I got this figured out. I copied over the example Makefile from this repo's examples folder.

I'm going to close this - if I have any more trouble I'll open another issue.
