Switch to using the tarball helper, that can generate reproducible archives whatever the tar version >= 1.27. However, those archives are not identical to the previous ones generated in the (now-broken) gnu format. To avoid any clashing between old and new archives, and new and old Buildroot versions, we need to name the new generated archives differently from the existing ones. So, we bump the git-specific format-version to -br1. The %ci date has been supported by git back to 1.6.0, released August 2008); it is not strictly ISO8601, but is still accepted as a PAX date header. The strict ISO8601 placeholder, %cI, was only introduced with 2.2.0, release in November 2014, so too recent to be widely available. As the format and the names of the archives changes, we need to update all the hash files with the new names and hashes. Of all the bootloaders that have a git download method, vexpress-firmware is the only one to have a hash. Others have no hash files, or they have explicitly set BR_NO_CHECK_HASH_FOR. For the packages, linux-headers is the special snowflake, as the git download is only for custom git tree, so it is excluded from the hash verification with BR_NO_CHECK_HASH_FOR.

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
