CCS: No source available for "0xfffa"

Other Parts Discussed in Thread: MSP430F5529, CC1120

Tool/software: Code Composer Studio

Hello,

While launching a program using CCS in MSP430F5529 Launchpad,I am getting this message "No source available for "0xfffa"" and i am unable to run it

Can you please tell me how to remove it and run the program successfully using CCS

    Hello,
    The debugger is simply saying that you are halted in a location where there is no source code correlation, hence the debugger is unable to provide source level debug. The message itself is nothing to be alarmed about.

    The bigger issue is why your program doesn't run. The message may be a clue - the target is halted at 0xfffa, where there is no associated source. Perhaps it is in a bad state or your program has a bug and went off "into the weeds". I don't have the answers as to why this is, you will need to debug your application.

    Thanks

    Table 6-1. Interrupt Sources, Flags, and Vectors of the MSP430F5529 datasheet shows that address 0x0FFFA is the interrupt vector for the "User NMI" interrupt source.

    If the program address is 0x0FFFA it is likely that the program has failed due to an interrupt occurring for which there is no interrupt handler.

    Without more details of your program I can't give a specific way to remove the problem.

    Hello Chester,
    My program is about updating code in flash memory.So for that purpose the packets were coming over the air through CC1120 and the download area will get updated accordingly .Once the download area get updated and validated it will e copied into application area and then updated code will start running.So i have changed the linker file contents for separating download are and application area.I think this updation of linker file is generating this issue.Please tell me how to come out of it to make the thins happen correctly.

    Thanks and Regards,
    Pavan

    Can you describe how the linker files have been separated.

    Also, at what point do you get the "No source available for "0xfffa"" error. e.g. does the error occur after attempting to run the updated code, or at some other point?

    You mentioned your program is about updating code in flash memory. Does this error occur before or after your program has attempted to update code in flash memory?

    Hello Chester,

    Actually it is giving this error before updating flash memory i.e. at the start of launching.

    Thanks and Regards,

    I am not sure what causes the error before updating flash memory.

    Under the CCS Auto Run and Launch Options if you untick the "On a program load or restart" and On a reset" Auto Run Options, to disable the attempt to run to main on starting a debug session, does that change the symptoms?
