How about the linux kernel ? I tried to compile linux kernel : according to README, but select linux as the platform. (BTW, the start num is 0 , not 1 as in README), but failed.
Using default config ...
make: Entering directory '/data/zzbdev/BPI-A64-Android/lichee/buildroot'
make: *** No rule to make target 'sun50i_defconfig'. Stop.
make: Leaving directory '/data/zzbdev/BPI-A64-Android/lichee/buildroot'
