LP-EM-CC35X1: Quickstart Example Key Activation Failed

Peter Borenstein
Prodigy 80 points
Part Number: LP-EM-CC35X1
Other Parts Discussed in Thread: LP-XDS110, LP-XDS110ET

Tool/software:

The Quickstart guide for LP-EM-CC35X1 explains how to activate the chip.

When attempting activation, The SimpleLink Wi-Fi Toolbox reports "activation failed". A screenshot is attached.

What are the consequences of this failure? Is the eval board wasted?

Upon further review, the instructions say "Make sure that both LP-XDS110ET and CC35x1 LaunchPad are connected to the same PC through two different USB-C ports." I did not follow this step. Only the LP-XDS110 was connected during the activation attempt.

    Hi Peter,

    Most likely you did not waste the board, this is a know issue.

    Sometimes there is a "fake" error message at the end of activation, even though the activation was successful.

    The way to check would be to go back to the home page of the toolbox, press programmer again, then try to connect to the device.

    The toolbox programmer should say whether the device is activated or not after connection. 

    Either way it is best to connect both USB-C ports to the host PC because we have seen in some situations that the power coming from the LP-XDS110ET is not enough, hence why connecting the second USB-C is also recommended. 

    Regards,

    Jonathan,

    Re-visiting the programming screen does indeed show "DEVICE ACTIVATED".

    Is there some way to proceed with the tutorial?

    The next step is "As part of the initial programming process above a precompiled network terminal example".

    I do not see any response to "help" on either COM port of the XDS board.

    Hi Peter,

    Once you have finished activation, you can proceed in 2 different ways - either use the precompiled example network terminal, or import one of the example CC35xxE projects to CCS and use them. 

    To use CCS with one of the example projects follow the user's guide which can be found in the docs folder of the SDK:

    CC35XX-WiFi-User-Guide.html -> SimpleLink Wireless MCU CC35xx Overview -> Software Overview 

    This will walk you through how to import a project and debug/ flash to the device.

    Regards,

    Jonathan
