binaries folder

Contains the generated binary files

• linux-2.6.xxx.bin
• rootfs.jffs2
• uboot.bin

build_arm folder

project_build_arm folder

This place is used to build the whole rootfs for your board.

• If you need to modify your rootfs (ie add nodes, startup files), you can do the modifications here during the development phase.
  

This folder is created during the first toolchain installation. A rootfs skeleton located in target/device/armadeus/roofs is used to build the initial rootfs.

• If you want to keep a special rootfs across projects, the skeleton has to be replaced with your own file.
  

The rootfs can be clean up with the following command:

$ make roofs-dirclean (in the top Armadeus directory)

target/device/armadeus folder
