CrossStudio version 2.3 has a option for CrossConnect to change the Target Interface type to SWD

I am looking to change that setting using CrossStudio 3.5 but I cant find it, How can I change the option from JTAG to SWD ?

Without changing anything I get the error of "Cannot set debug register".

Also tried to add a new target "USB CrossConnect for ARM" and look for the option but its still not there.

  It's a project property "Target Interface Type"

  I am experiencing a similar issue, except that I've added the arm_target_interface_type="SWD" property to my project configuration, and I still get "cannot set debug register" from Crossstudio and Crossload 3.5.

  I've attached a project file below.

  For an STM32 you can try setting the project property "Connect With Reset" to "Yes" - note that this requires the NSRST pin to be wired to the debug header. Alternatively if you have an option of forcing the chip into a bootloader mode this can be used. For development we recommend not setting STARTUP_FROM_RESET so the device is always in a known state after reset.

  Hmmm, that didn't change anything. I still get the same error, even if I set a 100 KHz debug clock rate. Other thoughts?

  BTW, this is all under Ubuntu 14.04, 64-bit OS. I haven't tried under Windows yet to isolate OS-dependency. Is there a driver update required?

  Behavior is identical under Windows 7 (with CrossStiudio 3.3).

  After much fiddling with target options, I've managed to convince the JTAG pod to connect to the target under reset. I think the fire is out.
