MSP430: File Loader: Data verification failed at address 0x00008000

Other Parts Discussed in Thread: MSP430F247

MSP430: File Loader: Data verification failed at address 0x00008000 Please verify target memory and memory map.
Error found during data verification. Ensure the linker command file matches the memory map.

 

Thats the error message I just started getting when I attempted to connect today. I am using the MSP430f247. My version of CCS is: 4.0.2.01003.

 

The only changes to my computer or to the hardware are:

  • Java Updates
  • New Power Supply

Now the new power supply is only needed to power all of the components of this circuit. I'm breadboarding so i have disconnected all components except for the microprocessor to ensure it has enough power (in the past the FET has been able to support nearly all of the power needed for this project). I do have a question though. Could this error message be a symptom of hitting the processor with too much voltage? I"m just trying to think of some possibilities.

 

On another note, its not just one CCS project thats failing to connect, its all of them. I have rebuilt every project with the same results. I have cleaned all of the projects with no go results either. I think i might reinstall CCS later today to see if that makes a difference.

 

Any help would be greatly appreciated. This kinda freaked me out when I couldn't connected at all to my microprocessor this morning.

    Hi,

    From your description the emulator is not able to write to the flash memory. This can be caused by either a JTAG fuse blown or the emulator or target board may be damaged, therefore to rule out any hardware issues I highly recommend reading the troubleshooting section of the MSP430 emulation page below:

    http://processors.wiki.ti.com/index.php/MSP-FET430UIF

    This page describes some simple methods that rule out any possible issues with the hardware.

    In addition, please check the section General IDE of the page below. It shows a few tricks to try to reset the workspace in case anything became corrupt or invalid.

    http://processors.wiki.ti.com/index.php/Troubleshooting_CCS 

    Answering your question, I haven't personally tried but I imagine that supplying the MSP core with a voltage beyond its specifications is probable cause for connection issues, errors in flash erase/write/read operations and subsequent collapse of the device's functionality.

    Hope this helps,

    Rafael

    Thanks for the reply.

     

    I did find out after posting my initial question that I did accidently power the entire circuit with 9V (Feedback connection on the VReg was loose). The more I think about it, the problem is hardware. Thanks for pointing me in the right direction.
