TF-A prints a version string at boot which includes the version number as specified in the Makefile and additional "build" information, specified by the BUILD_STRING parameter: https://trustedfirmware-a.readthedocs.io/en/v2.9/getting_started/build-options.html BUILD_STRING: Input string for VERSION_STRING, which allows the TF-A build to be uniquely identified. Defaults to the current git commit id. This is implemented as: # Default build string (git branch and commit) ifeq (${BUILD_STRING},) BUILD_STRING := $(shell git describe --always --dirty --tags 2> /dev/null) endif https://github.com/ARM-software/arm-trusted-firmware/blob/master/Makefile#L225-L228 Which is never correct in the context of Buildroot, as the TF-A build directory is never a git repo, and git will move up the directory tree and possibly and (possibly) pick up the git version of Buildroot instead. To fix that, explicitly set BUILD_STRING to the version of the package. Pass it before BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES so it can still be overridden by the user if needed. strings images/tf-a-* | egrep '^v2\.' v2.9(debug):2023.08-859-g99d78b52a0 v2.9(debug):v2.9 Signed-off-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> (cherry picked from commit 5a8a7530bfb37017c08f768693f7581992dc033c) Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
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 OFTC IRC.
