Linux version 2.6.12.6-arm1 (root@dev-hara2) (gcc version 3.4.4 (release) (CodeSourcery ARM 2005q3-2)) #4 Fri Aug 3 10:34:52 JST 2007
カーネルは、2.6.12.6-arm1
CodeSourcery ARM 2005q3-2 ということは、 http://www.codesourcery.com/gnu_toolchains/arm/releases/2005q3-2 から ダウンロードできるクロス環境を使っていると考えられる。
まあ、ARM 系全 LinkStation で開発環境を同じにしておいたほうが良いわな。
