It sounds like the JTAG Link can't halt the processor. Assuming you've double checked the physical connections, I'd recommend disabling the flash chip by shorting pins 1 and 4 on p5 together, power cycle the module, and see if it can then halt the processor.

thank for your replay
but they don't work...
i have disabling the flash chip by shorting pins 1 and 4 on p5 together but nothing... (it is similar, i can't connect Jtag to module)
for the cablage, i can plug a digi connect-wime module and they work.
some idea?

What do you see in GDB after you short the pins together (and reboot)?
