Save buildroot configuration

In this page we will lean how to save buildroot and linux configuration for a project.

Buildroot

To save buildroot config use the command :

$ make savedefconfig

The saved config file will be available in file buildroot/defconfig.

To save it under a board config file, merge it with config file available in:

$ vimdiff buildroot/defconfig buildroot/configs/<BOARD_NAME>_defconfig

If kernel used is > 2.6.36, a script is available in the armadeus directory /scripts/. Under the bsp directory, type:

$ ./scripts/export_linux_config.sh
[...]
Please enter your favorite merge tool (ex: kompare, vimdiff, etc...)
> vimdiff

And give your favorite diff tools then press enter. Under your diff tools, do the merge. The final config file will be saved in :

buildroot/target/device/armadeus/<BOARD_NAME>/<BOARD_NAME>-linux-<KERNEL_NUM>.config
