Hi Ian, I try compile the bootwrapper for cubieboard2 like this: joshzhao@joshzhao-ThinkCentre-M58p:~/project/Xen/A20/boot-wrapper$ make cubieboard2_defconfig CROSS_COMPILE=arm-linux-gnueabihf- # # configuration written to .config # joshzhao@joshzhao-ThinkCentre-M58p:~/project/Xen/A20/boot-wrapper$ make CROSS_COMPILE=arm-linux-gnueabihf- make -C scripts/kconfig -f Makefile.bootwrapper
