The logic we have for the installation of the firmware files is, to say the least, non conventional. It is split in two parts: - one that copies files via an intermediate tarball: the tarball creation is used to detect if firmware files are missing (i.e. on a version bump) and fail the build if so, while the tarball extraction is the actual firmware installation; - one that copies directories one by one in a loop, removing the destination before the copy, to maintain a proper layout. Needless to say, this is not very clean. First, there is no reason why the directories can not be copied with the same mechanism as the files themselves; not sure what I had in mind with b55bd5a9e25e... Second, we're soon going to need the same installation step to copy the firmware files in the images/ directory, to ease embedding in the kernel image. Rationalise this installation procedure. Cherry-picking files and directories with cp, while still maintaining the directory layout, is not trivial; rsync is not one of our pre-requisites. So we're left with tar, which makes it easy. So we keep using an intermediate tarball, but we use it for both files and directories, and we generate it at build time, not install time. That archive is then extracted during the installation. Now the installation complexity is mostly located in the creation of the symlinks, so we merge all of that directly into the _INSTALL_TARGET_CMDS and drop the intermediate macros that have no longer any reason to exist. This will also make it pretty simple to later install in the images/ directory. Reported-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
