SimBCM - A Full System Simulator of BCM1250
Broadcom BCM1250ってMIPS64デュアルコアなのかぁ、遊んでみたいなぁ・・・とか思って、ググッてみたらCisco 7301がヒットして、思ったとおり1,159,800円もしてショボーン(´・ω・`)としてたら、なんかエミュレータ見つけたよ
マニュアルがあるので、これの通りにインストールすればすんなり動いた。
が、configureなどを使う一般的なUNIXアプリの書き方をしておらず、Linuxきめうちなのでちょっと環境が違うと多分うまくいかない。少なくともFreeBSDでは駄目そうだった。
マニュアルと同じだが、一応画面メモ。
残念ながら、結構遅い。
Harddisk emulationは無くて、Flashやイーサネットだけが見えている状態らしい。
このイーサネットは本当に通信できるのだろうか？謎。
