No TDO with JTAG at startup

Hi guys !

We've just finish our first prototype with at STR912. Unfortunatly the startup sequence don't work. Using JLink.exe, we have all the good JTAG signals (as show in JLinkARM.pdf) but the uC don't respond through the TDO signal. We have good voltage everywhere but it's seem that the core is not well reset.

Any clue ?

Thanks
