Hi!
Thank you Sergio.I don't know why part of my previous message lost...The
ICE Test is successful, finding out 1 device in JTAG chain, and the continuous
scan is successful too.But when going on,VDSP says Unable to halt processor.JTAG
communication failed...Reseting when activating VDSP session does not work.My
JTAG port connection: Pin 5 pull-up by a 4.7kohm resistor,TMS,TDI and TCK
pull-up by 10kohm resistors,TRST- pull-down by a 4.7kohm resistor,others
connected to ground.Thanks.
