I am trying to program my Tiva C LaunchPad with the XDS200 Emulator and get the following error message in CCS and UniFlash.
Error connecting to the target:
(Error -2172 @ 0xD)
Unable to communicate with the emulator. Confirm emulator configuration and connections, reset the emulator, and retry the operation.
(Emulation package 5.1.232.0)
It is possible I have done something wrong with the way I have hooked up my pins. So any advise on which ones go where, would be great.
The Tiva C LaunchPad has the following pins
TCK, TMS, TDO, TDI, EXT DBG, TXD, RXD and Reset
The XDS200 has the following pins when using the ARM20 Adapter (starting with pin 1)
VTRef, Vsupply, nTRST, GND, TDI, GND, TCK, GND, RTCK, GDN, TDO, GND, nRESET, GND, DBGRQ, GND, DBACK, GND
I have connected the following to each other.
LaunchPad ARM20 Adapter
TCK --------------> TCK (pin 9)
TMS --------------> TMS (pin 7)
TDO --------------> TDO (pin 13)
TDI ----------------> TDI (pin 5)
EXT DBG ---------> GND (It states here - Pull this pin low to tri-state the on board ICDI drive signals. This prevents the ICDI from interfering with an external debug-in connection.)
TXD (not connected)
RXD (not connected)
Reset ---------------> nTRST (pin 3)
Does this look right? If not what are the changes needed? If it is right, what else could be causing my error message?
The Tiva C is being powered externally via its USB Host Connector.
Glenn.
