Buildroot for NanoPi NEO Core hello project
How to Build
- For buildroot-2019.02.3, Ubuntu 14.04 32bit
$ sudo apt-get update
$ sudo apt-get install g++ git libncurses5-dev
$ cd buildroot-2019.02.3
$ make help
$ make list-defconfigs
$ make nanopi_neo_defconfig
$ make menuconfig
(Enable Toolchain->Enable C++ support)
$ make
(Get sdcard.img under output/images/)
(Put hellocpp and helloworld to package/)
(Modify package/Config.in)
...
menu "Miscellaneous"
...
source "package/helloworld/Config.in"
source "package/hellocpp/Config.in"
$ make menuconfig
(Enable Package->Misc->helloworld, hellocpp)
$ make
(After modify hellocpp source)
$ make hellocpp-dirclean && make
(Get new sdcard.img under output/image/)
(Flash sdcard.img to tf card using Win32DiskImager, over)
