Boundary Scan problem STM32L100RB

I'm trying to run Boundary Scan on a board with a STM32L100RB mcu. It is the only Component in the boundary scan chain, but I can't get it to work. I get nothing at the JTDO pin. Anyone have any idea what might be wrong?

The MCU is programmed, but in reset mode since I keep the nRST pin low. The software enginner Writing the program says there are no fuses set, and he has been able to get a connection to the component through the JTAG TAP even after programming.
The board is powered, and I have signals from my boundary scan controller on TDI, TMS and TCK.
BSDL files used are CortexM3.bsd and STM32L1_Med_density_LQFP64.
In the reference manual (DocID15965 Rev 12 ) figure 291 it looks like the Cortex-M3 device should be last in the boundary scan chain, but my boundary scan software (Corelis TPG) can not generate an infrastructure test unless I put CortexM3.bsd before STM32L1_Med_density_LQFP64.
