Update feeds:
./scripts/feeds update -a
./scripts/feeds install -a



Typical actions:

    run make menuconfig and set target;
    run make defconfig to set default config for build system and device;
    run make kernel_menuconfig (optional);
    run make menuconfig and modify set of package;
    run make download (download all dependency source files before final make, enables multi-core compilation);
    run scripts/diffconfig.sh >mydiffconfig (save your changes in the text file mydiffconfig);

yo supongo que esto sera:
   make menuconfig
   make download
   make
