This tool might be useful on Android devices modded with Buildroot. Indeed
it allows to modify Android Boot Image partition directly from running
rootfs and so let the user free to keep Android stuff on his device
(mainly bootloader) while testing/using Buildroot kernel/rootfs.
For example, one can modify kernel cmdline on Boot Image partition and
tell Android bootloader to launch kernel with a given rootfs fitted with BR
instead of Android's one.
Build-tested with ./utils/test-pkg -p abootimg -c config.abootimg -a
with config.abootimg containing:
BR2_USE_MMU=y
BR2_PACKAGE_ABOOTIMG=y
BR2_PACKAGE_UTIL_LINUX=y
BR2_PACKAGE_UTIL_LINUX_LIBBLKID=y

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
