When CONFIG_FIT_SIGNATURE is enabled for building, CONFIG_FIT_SIGNATURE_MAX_SIZE must be defined since it's a dependency of CONFIG_FIT_SIGNATURE. Using uboot Kconfig, CONFIG_GIT_SIGNATURE_MAX_SIZE is set to its default(0x10000000) according to Kconfig, but Buildroot doesn't use uboot Kconfig, it passes directly CONFIG_* as make arguments. Append CONFIG_FIT_SIGNATURE_MAX_SIZE=0x10000000 after CONFIG_FIT_SIGNATURE=y to UBOOT_TOOLS_MAKE_OPTS and HOST_UBOOT_TOOLS_MAKE_OPTS.

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.
