I have developed an interface for IAR jtag/jtrace to an SBPT2500C2.AT board with integrated STM32F103XE Microcontroller.
The schematic interface from Jtag to SBPT Board is based on the interface schematic of the IAR STM32-SK board (pull-up resistor for TRST, TDI, TMS, TCK, TDO - Series Resistor and free line for other pin).
The connections of the jtag with SBPT module across the interface circuit are correct.
In the active project of IAR EWARM, I have selected the debugger driver option to Jlink/Jtrace; The Jtag/Jlink options are selected by defoult to JTAG, Auto Speed, Normal Reset).
When I start the Download and Debug process, I see this session log:

====
The Power Supply applied at the circuit is finded from Jlink interface (value about 3.55v).
What Can I do?
