**jtag_speed [#id6206cf]
jtag_speed 0を入れると安定した
jtag_speedは　Deprecated/Removed Commands　だそうだが、使える。
 cf, http://openocd.berlios.de/doc/html/Upgrading.html#Upgrading


また、jtag_speed 0 は max speedとなるのだが、速度を遅くした方が動作が不安定になるのが不思議。
また、jtag_speedを指定しないと6000khzになる。jtag_speed 0を指定した時と同じ条件のはずだがどうして動作が違うのかという点も謎。
**cfgファイル [#n9ca6ef5]
at91sam7sx.cfgをat91sam7lxとしてコピーして使ったが当然ながらうまくいかない。
データシートを見比べるとリセット関係のレジスタが微妙にずれている。
修正して対応。しかし、at91sam7sxのデータシートが変に誤植していてわけがわからない。
