Schematics for CMSIS-DAP

Great work on this interface, as part of the HDK I think it would be very helpful to show a recommended schematic for the CMSIS-DAP interface using either the LPC11U35 or KL25Z. At a minimum it would be nice to know what package version the interface is targeting and what pins have what functions and if they require extra series resistors or other components.

Also in the documentation it is not always clear if the "target" is the device connected to the CMSIS-DAP or the microcontroller that the CMSIS-DAP firmware is running on.

Question relating to:

CMSIS-DAP, debug, mbed, mbed Interface

Hello,

have you visited freescale webpage? The schematic for KL25Z is available which contains the entire openSDA circuit.

Thanks. It is unclear to me however if openSDA and the mBed interface are the same thing. Of course they both implement ARM;s CMSIS-DAP but are they the same code, pin assignments, etc?

Also I have not read into openSDA completely but I'll need to determine if it is restricted by license to debugging only Freescale ARM devices.

I think this is what you're looking for. http://mbed.org/users/mbed_official/code/mbed-HDK/

Let me know if it's not!
