CCS/MSP430G2553: FET was Not found

Part Number: MSP430G2553

Tool/software: Code Composer Studio

Hello,

I am using MSP430 (2553) Currently one more issue during debugging error like this  "No USB FET was found"  when I remove the UART jumper then working fine but put back to UART jumper in hardware configuration then not working but in software UART condition working fine. And also my MSP COM port show on Com port menu its good. Also, my CCS version is V8.3.0. I am having 5 launchpad board all this board this problem.

How to resolve this problem?

    Hey Yash,

    Can you confirm that you are using the new G2 launchpad as seen here? www.ti.com/.../msp-exp430g2et
    What UART Jumpers are you removing when you see the error go away?
    How many launchpads are connected to the computer at the same time?

    Typically, the No USB FET was found is an issue between the computer and the ez-FET, Not between the ez-FET and the MSP430G2553. Most common is when the launchpad just isn't plugged into the computer. If you plug in the Launchpad with not programming jumpers connected, you should get a "Target device not found" type message when trying to program. Is this the case?

    Thanks,
    JD

    Hello,

    Yes I am using the MSP2553 G2 launch pad.

    Yes i am Remove the Rx and Tx of UART jumper then board working fine but that case only hardware jumper setting . Here i am put the jumper in software UART mode then board also working but UART communication not possible.

    At a time only one launchpad connected.

    so how to resolve this problem? Bacuase i am having 5 board and all board same problem.

    Hey Yash,

    Sorry for the delay, I was traveling.

    For the UART modes, HW and SW just route the UART signals differently. To use the USCI_A0 Module, you should have they pins in HW-UART mode. In SW mode, you would need to us a Software defined UART. This is done in some of the MSP430G2 Launchpad examples, such as the out of the box demo.

    These should not have an impact on the being able to program the device. These are only for the back-channel UART connection back to the PC for a COM port connection.

    Thanks,
    JD
