CCS/TDA4VMXEVM: Waiting for user input in Console

Part Number: TDA4VMXEVM

Tool/software: Code Composer Studio

Dear experts,

I'm using CCS to debug my code to J721E_EVM target. When I click on Resume(F8) I see the following in Debug tab:

In my code, there is no function that waits for an input.

I go to Console and type two random numbers, then it turns to "Running".

Do you have an explanation about this input?

Regards,

Brahim

    If you manually halt the target at that point, where (in the source) are you halted?

    Thanks

    Halt R5_0_1 via 'Run -> Suspend' menu item.

    Ki,

    When it shows "Running - waiting for user input,,," and I click on Suspend, I got this:

    In your call stack, you can see that scanf was called. Looks like it is waiting for input from the serial terminal.

    Ki,

    The serial terminal is the same CCS console ?

    No, they are different. But it is possible to re-route C I/O to use a different transport like serial so that it can be used from a serial terminal/console.

    Thanks
