Hi Chris,
I'm not an expert, nor a typical poster on this list, but have you properly
configured the DBGMCU_CR register to allow debugging support while the STM32
is in STOP mode?
Best,

Hi all,
I'm using OpenOCD (version 0.4.0, downloaded from SourceForge and built
about half an hour ago) on Debian Lenny (5.0, stable) running under
VMWare Fusion on an x86 Mac Pro. The microcontroller I'm using is an
STM32F103C6T6, and the JTAG dongle is an Amontec JTAGKey. By and large
