SATAに接続されたストレージからのブートの場合、1つ目のパーティションのFS内に存在するKernelバイナリをU-Bootが読み出してブートする。2ドライブモデルのHDL2-Aにおいては、OSデータを持つストレージを接続するSATAポートはおそらくどちらでも良い。
FSはext2/3に対応していると思われ、ext4はU-BootでのマウントかKernelバイナリの読み出しに失敗している模様。
テストに使用したinitramfsイメージは下記にあるOpenWrt公式ビルドのもの
USBストレージからのブート時と同様、initrdバイナリも要求されるので適当に0埋めで0byteを超えるサイズで作成しておく。
