1. Confirm that `image/sd.img` is built and burn it to an SD card.
Build a Buildroot rootfs
------------------------
Buildroot rootfs aims to be the most lightweight rootfs for experimental use. `make buildroot_rootfs` runs the defconfig target for rootfs-only build and then builds the rootfs tarball and a CPIO archive for initramfs. `make image/sd_buildroot.img` makes a bootable SD image in `image` directory like the typical Brainux SD image.
If you want to customize the build of Buildroot, `cd` into `buildroot` and use the following targets:
- `make menuconfig` to change the configuration
- `make` to build the rootfs (`-j` option might give you extra speed)
`image/sd_buildroot.img` target expects presence of the tarball at `buildroot/output/images/rootfs.tar`. You'll have to `clean` and rebuild every time you change the Buildroot's config before making the SD image.
Known issues
----------------------------------------
If you using gcc 10 for host compiler, `make ubuild` may fail.

To complete build, open `/u-boot-brain/scripts/dtc/dtc-lexer.lex.c` or `/u-boot-brain/scripts/dtc/dtc-parser.tab.c` then comment out `YYLTYPE yylloc;`
