突然NASに興味を持ち、ヤフオクなど漁った結果安価な出品があったので確保したもの。
事前情報でシリアルコンソールの入力を受け付けないという話はあったが、とりあえずトライしていくことにした。
弄っていくのでメモ。
U-Boot
事前情報通り、U-Bootにおいて入力が受け付けられず（というより恐らくは中断プロンプトが無効化されている）ブートシーケンスを止めることができない。
ブートの際、まずSATAに接続されているストレージからのOS読み出しを試行し、SATAに接続されていない、あるいはOSデータが読み出せない場合は、USBポートに接続されているストレージから特定パスのOSデータ読み出しを試行する模様。

なお、OpenWrtではinitrdは必要無い為当初0byteのinitrdファイルを置いたが蹴られ、/dev/zero を利用して64KB（サイズは適当）にしたところ通過してOpenWrtがブートされた。============================================================ HDL2-A series Initial boot loader Copyright (C) 2008-2011 I-O DATA DEVICE, INC. ============================================================ ** LOADER ** ** MARVELL BOARD: HDL2A LE U-Boot 1.1.4 (Aug 27 2011 - 16:33:44) MV : 3.5.9 I-O : 1.03 U-Boot code: 00600000 -> 0066FFF0 BSS: -> 006BDAE0 Soc: 88F6282 A1CPU running @ 1600Mhz L2 running @ 533Mhz SysClock = 533Mhz , TClock = 200Mhz DRAM (DDR3) CAS Latency = 7 tRP = 7 tRAS = 20 tRCD=7 DRAM CS[0] base 0x00000000 size 256MB DRAM Total size 256MB 16bit width Addresses 8M - 0M are saved for the U-Boot usage.
