I can work on this, if you point me to the docs.

Its mostly implemented now. I see that the main work is pushed already. Once you have configured the project to select the raspberrypi board you are using simply type:

make defconfig

It should then use arm-none-eabi- compiler by default and just build (I hope).

There's also a cleaner mechanism than adding code to bt_main.c to get your own code into BitThunder.

Create a new folder outside of the BitThunder tree then inside that folder run the following command:

make -C ../bitthunder/ PROJECT_DIR=$(pwd) project.init

(Where ../bitthunder/ is the path to your bitthunder kernel source tree).

From the project folder you'll see an objects.mk file with the following contents:

objs += $(APP)/main.o

$(APP) is your project folder relative, and so you can add as main objects to the build as you like.

Simply add a function called main inside main.c to override the default BitThunder main.

I just pushed some fixes to make this all work correctly, so give me a shout if it doesn't work.

I've updated the post, to use the approach you suggest, and it all seems to be working, give me a shout if there are any changes I should make.

Hi Richard,

I've put a link to your tutorial now on the main website. http://bitthunder.org/docs/quick-start/

I'll add it to some other places and make a blog post too to make it more prominent.

Your updates look great.

James

:smile: thanks! I'll contact you if I post anything else on it.
