Due to recent changes in U-Boot, see http://git.denx.de/?p=u-boot.git;a=commit;h=a26cd04920dc069fd6e91abb785426cf6c29f45f re-creation of .config from defconfig by "make oldconfig" happened incorrectly. Default prompt for target selection was set as No that lead to missing platform selection by automated scripts like that: ------------------>8------------------ "yes "" | make oldconfig" on defconfig ------------------>8------------------ And that lead to build failure: ------------------>8------------------ $ make scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config.h UPD include/config.h GEN include/autoconf.mk In file included from ./include/common.h:18:0: include/config.h:5:22: fatal error: configs/.h: No such file or directory #include <configs/.h> ^ compilation terminated. scripts/Makefile.autoconf:72: recipe for target 'include/autoconf.mk' failed make[1]: *** [include/autoconf.mk] Error 1 ------------------>8------------------ This patch reverts mentioned change making possible to build U-Boot 2015.07 in Buildroot. Note there's a probability that this particular patch won't make its way in upstream U-Boot and better solution will be found there. But for now we need to fix U-Boot building in Buildroot anyways. Hopefully for the next release this patch won't be necessary.

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.
