I got it finally, but not root cause.
reproduce:
1. connect jtag with openjtag(not the official openjtag, but 100ask.net produced
based on openmoko's).
2. use ON/OFF switch on the board
then I got "Wrong databus"
but if I disconnect the power line, and reconnect it, everything OK.
and if not connect jtager, and use ON/OFF switch, everyghing OK.
what's the fuck problem?
