It is suitable for ColdFire® Processors up to 266 MHz Clock and 3.3 V Pad Voltage. It is 100% compatible with the Standard Parallel Port Wiggler and works with all COBRA Processor Modules (COBRA = ColdFire® Board for Rapid Applications): COBRA5272, COBRA5282, COBRA5475, COBRA5485, COBRA5329, COBRA52235. The COBRA Connect BDM Interface has been tested and works fine with the following tools: GNU Compiler (gcc), GNU Debugger (gdb), Freescale CodeWarrior, CF flasher, BDM Flasher. However, it should work also with all other tools compatible to the Standard PC Parallel Port Wiggler. The COBRA Connect BDM Interface has been tested and works fine with the following Processors: MCF5206E, MCF5213, MCF52235, MCF5272, MCF5282, MCF5235, MCF5475, MCF5485, MCF5329. However, it should work also with other Freescale ColdFire® Processors. The 100mil 26-Pin Target BDM Interface Connector is compatible to the FreescaleRecommended BDM Pinout (26-pin Berg connector arranged 2 x 13) as described in the User’s Manuals of the ColdFire® Processors. When you connect the BDM interface to the target, please make sure that you connect pin 1 of the BDM interface connector to pin 1 of the target connector. There is no mechanical lock to prevent the BDM interface from reverse connection. If you connect the BDM interface to the target reversely, it will not be destroyed, but just will not work as expected. The COBRA Connect BDM Interface is been powered from the debugged target. The power supply voltage should be within the range of 2.3 to 4.6 V. When a supply voltage is applied to the BDM interface, the green LED “Power” indicates that the BDM Interface is powered. The red LED “Halt” indicates that the processor is in halted state. If you connect the BDM interface to a target, power up the target and the green LED “Power” does not light up, check if you have connected the BDM interface the right way (or if it is reversed). The COBRA Connect BDM Interface has been tested and works fine with the native Parallel Port of standard IBM-compatible Personal Computers and Notebooks. However, it has not been tested with USB based Parallel Port Emulators! If you use a Parallel Port Emulator or a Port Replicator, the COBRA Connect BDM Interface may not work as expected. © Copyright senTec Elektronik GmbH 2006.
