I use a new J-Link V6.0 with Software 3.80c.

I want use it with GDB Server. I have a "Cortex-M3, Core Id: 0x3BA00477". = STM32F103CB

Now, I have the connection SWD (special cable, connected like documentation). But the J-Link software make only the error:

"Bad JTAG communikation: Write to IR: Except 0x1, got 0x0 (TAP Command : 15) @ Off 0x5."

What can I do?

Thank you for help, Regards Markus.

The JLink.exe says "****** Error: Could not find supported CPU core on JTAG chain"

In the help from this tool, I have never found a switch to "SWD", or scan the J-LINK automaticly the SWD Bus?

If I connect my device as JTAG then the result is :
Info: totalIRLen = 9, IRPrint = 0x0011
Infog: Found Cortex-M3, Little endian.
Info: TPIU fitted.
Info: FPUnit: 6 code (BP) slots and 2 literal slots
Found 2 JTAG devices, Total IRLen = 9:
Id of device #0: 0x3BA00477
Id of device #1: 0x16410041
Cortex-M3 identified

I use the Olimex development Board "STM32-P103"

Thank you for help. Regards Markus.
