error during load the program

      i do work on DSP TMS320Lf2407A and using ccs v 3.1 when i load the program into dsp and select the file -> load program then is how the message "data verification address failed".

Usually that means that CCS could not write to the memory location that the program is built for and the most common reason is a mismatch between the debugger memory map (which is what CCS uses to determine is a memory region is readable/writable) and the linker command file (see section 4.5.4 of  SPRU024E) used to build the project. Try checking both for accuracy.

Shobhit,

Are you trying to load code that is supposed to be in internal Flash using the CCS menu File->Load Program? If so, you would see the "data verification failed" message because you need to program to FLash using the On-chip Flash programmer plugin in CCS.

and when i am using flash programmer in tools bar the i have a error " Read status value 0x0003 from symbol PRG_status Flash algorithm failed during program operation" 

Is it possible that the flash is locked when you are trying to program using the On-chip Flash programmer? Could you have accidently overwritten the password locations with some code when previously programming it? If this did happen, the flash is locked and you will need to unlock it by using the correct password before you can reprogram the flash memory.

You could also try programming using the standalone SDFlash utility available from Spectrum Digital to see if that works: http://emulators.spectrumdigital.com/utilities/sdflash/

If that fails as well, you may need to replace the device.
