When the trusted firmware is built with debug support (DEBUG defined), the generated images are located in a different path compared to a build without debug support. The non debug images are located in generated directory build/<platform>/release/ while the debug images are located in generated directory build/<platform>/debug/. This change introduces the boolean option BR2_TARGET_ARM_TRUSTED_FIRMWARE_DEBUG to define whether the release or debug configuration is used to build trusted firmware. Note that enabling trusted firmware debug support using BR2_TARGET_ARM_TRUSTED_FIRMWARE_ADDITIONAL_VARIABLES="... DEBUG=1 ..." would not work since Buildroot will try to copy the generated files from the wrong path.

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.
