Help : device detected but I get an error

Hi,

I try to connect on my target whith openocd and jatgkey.

But when I run openocd-ftd2xx.exe, I get an error :

Open On-Chip Debugger (2008-06-19 19:00) svn: 717 
URL: http://svn.berlios.de/svnroot/repos/openocd/trunk 
Info: options.c:50 configuration_output_handler(): Open On-Chip Debugger (200 
8-06-19 19:00) svn: 717

Error: jtag.c:1456 jtag_validate_chain(): Error validating JTAG scan chain, IR 
mismatch, scan returned 0x01

The device found, is my component (arm9 TI Davinci).

Why I get this error ?

Here is my file config :
