MSP-FET430UIF LED Indications

Other Parts Discussed in Thread: MSP-TS430PW28

I'm trying to debug an out-of-the- box configuration of an MSP-FET430UIF with an MSP-TS430PW28 (Rev.3.1) eval board from the same kit.

The IAR Workbench message is "Fatal error: Could not find device (or device not supported)   Session aborted!"

I'm trying to use the Mode and Power LEDs on the UIF to isolate the problem to either the computer-to-UIF path (including the USB driver set-up or the Workbench options) or the UIF-to-target path.

Searched many manuals but couldn't find a description of the proper and erronous behaviour of these LEDs, both with the targe connected or with it disconnected.

In my case,  when I get the error message both the red Mode LED and the green Power LED are lighted.

Does anyone know where the operation of these LEDs is described or have a discription of what they should be doing?

Is there a better way I should be trying to isolate the problem than trying to understand these LEDs?

    Hi James,

    That error message and behavior you described looks to me more like the IDE does not recognize the device in the socket of your MSP-TS430PW28 target board than being a problem with your FET tool. The fact that both LEDs were on means that the IDE has actually accessed the debugger hardware (so it found it) but the error message indicates it is not recognizing the MSP430.

    • What device do you have in the socket of the target board?
    • Have you confirmed that it is correctly oriented in the socket?
    • Have you confirmed that the power jumpers on the target board are properly selected for how you are powering the board (from the FET tool or externally)?
    • If you're powering the board externally, have you made sure it is getting a high enough voltage to program the part based on the data sheet min voltage value for flash programming?
    • What version of IAR do you have?

    For future reference, there is a short checklist here on troubleshooting the FET tool: http://processors.wiki.ti.com/index.php/MSP-FET430UIF#MSP-FET430UIF_Troubleshooting

    And you should also be aware of this if you are switching between different versions of your IDE (there's also a number of forum posts on the subject): http://processors.wiki.ti.com/index.php/MSP_Debug_Stack#MSP-FET430UIF_Debugger_Up-_and_Downgrade

    Katie,

    Pointing me to the target board as the source of the problem sent me quickly to the solution.  The board came from the factory configured for the Spy-Bi-Wire mode.  I had selected the (C) project in the getting started workspace.  Selecting the (C - SpyBiWire) project solved the problem right away.

    The 2 references were helpful in getting a bigger picture of the FET UIF tool.

    Thank you.

    Best Regards,

    Jim
