ZYBOで遊びましょ！ linux ファイルシステムをSDに

ふと、petalinux-configでなつかしいコンフィグ画面が出てきたのを見て、
あぁ、、、これでxinitが必要だったのか、、、でスルーしたのを思い出して再挑戦。
ちゃんと設定できるようになってました。

SDのパーティション
BOOT.BINとimage.ubはFAT32、rootfs.ext4はlinuxなのでパ−ティションを切る必要があります。
これ、FATとlinuxの間に隙間を作らないと、
スーパーブロックなんちゃらとエラーが出ます。
隙間は2048ブロックあれば良いようです。
これ、fdiskでパーティションを切った場合の話しで、いまどきのツールだと必要なかった！というような話しもあるようです？

細かな手順は書きませんが、バージョンはちょっと古くてもネットで検索すれば丁寧な解説がでてきますからそちらを参考にすればすぐにわかると思います。
