Hello,

only an idea. Perhaps the olimex usb ocd had a power problem.

Can you check it with a powerd hub where you connect the

olimex usb ocd.

very thanks for your reply!i will check it and give the result.

i find olimex usb ocd would resume 300ma power.so my usb hub could not pay out.i think this is the key! i could not make it job untill now !
