I am using GM862 with the evaluation kit EVK3 USB version…when i programme it,it will automatic turn off by itself >.<

I alrdy plug in an adapter with 4.5v supply and the USB port i plug at the port at the behind of the CPU…theorectically it should be enough power to run it…but it still will turn off…(this is only happend when i m using it either through Rsterm or Hyperterminal,if I on it and just leave it there it wun turn off…)any1 help pls???

It can take 3A peak current momentarily. Can your supply handle that? Do you have the specified capacitor across the power pins of the GM862?
