sheevaplug.cfg をググっていたら、squeeze, sid にはopenocd が、パッケージとして存在するらしい。 http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/debian-testing-i386-netinst.iso をダウンロードし、CD-ROMを焼き焼きして、
squeezeをクリーンインストール後、
squeeze:/home/nitobe# cat /etc/debian_version squeeze/sid squeeze:/home/nitobe# uname -a Linux squeeze 2.6.26-2-686 #1 SMP Sun Jun 21 04:57:38 UTC 2009 i686 GNU/Linux squeeze:/home/nitobe# aptitude install libusb-dev libftdi-dev libboost-dev openocd squeeze:/home/nitobe# find /usr -name sheevaplug.cfg -print /usr/share/openocd/scripts/interface/sheevaplug.cfg /usr/share/openocd/scripts/board/sheevaplug.cfg
既に、cfgファイルは、/usr/share/openocd/scripts/board/ に存在する。
