Hello, I am looking into this matter. However I was not able to get a satisfactory answer before our offices closed for the end of year holidays. I will look into this and review it once our offices open back up again on the 2nd of January.

Vrishab, First of all, you might want to consider upgrading to the most recent 4.0 release of CodeWarrior which has major enhancements over the 3.5 version of the tools. If you would like to do so, please contact the appropriate sales representative by looking at: http://www.metrowerks.com/buy/ It sounds like your project is missing the necessary interrupt vectors in order to boot in standalone mode. You can program the flash through either just using the integrated debugger through CodeWarrior or by using a serial bootloader application which comes contained within the SDK. With the combined package of the CodeWarrior R4.0 and SDK R2.4 you can find many examples of projects capable of running in standalone mode for almost all of the DSP56F8xx line of processors and their EVM's. Not only that, but there is sample stationery provided for this purpose as well for you to be able to do it on your own. If you would like for us to look at your project and diagnose the problem you will need to go through technical support at or by calling 1-800-377-5416.
