Migrating the support for this feature to uboot-tools to gain the ability to build env files when BR2_TARGET_UBOOT isn't selected. When _ENVIMAGE_SOURCE is not set, we generate a default environment. However, this default depends on the U-Boot configuration. Therefore, this can only be done if uboot itself is built as well, and host-uboot-tools needs to depend on uboot. For the same reason, the commands for creating the environment have to be adapted a little. Take this occasion to drastically simplify them. Note: This patch creates a circular dependency with uboot until the similar migration patch is merged for uboot scripts Cc: Arnout Vandecappelle <arnout@mind.be> Signed-off-by: Matthew Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
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.
