ADSP-21469 not booting after being programmed

I programmed my ADSP-21469 EzKit successfully using the CLDP and an ICE-1000. I set the loader file up to program the parallel flash memory. The command line reported that the programming was done. I set the boot switch (sw4) to position 2 for booting from the parallel flash memory. Then I reset my board.

Unfortunately it seems that either the program didn't take, or the board isn't booting. I'm not sure what the problem is but the program runs fine when I run it though CCES and the emulator, but I just can't seem to get it to run on it's own. Any help you can give me would be much appreciated.

  • Hello,

    Attached zip file contains a loader file for the ADSP-21469 LED_Blink code and associated file for programming this into the parallel flash. Can you invoke the CLDP command via command prompt and load the program to see if the Ez-Kit is booting from parallel flash. I use debug agent to load the program and it booted successful in my ez-kit.


    Best Regards,


  • I loaded the file that you sent me onto the ADSP-21469. I had to modify the script txt slightly by pointing it to the driver dxe I have here, and to use the ICE-1000.

    Everything seems to have gone okay with the deployment.

    I hit the reset button on the board but the LED turned on and stayed green. Should it be flashing on and off if it booted the program here?

  • Please see my comments.

    1) I don't think you are not using correct diver file for parallel flash.  Looking at the image showed above, seems the driver file is for SPI flash (M25P16).

    Please use the driver file for parallel flash (M29W320) from the below path,

    <ADSP-21469 BSP installation directory>\ADSP-21469_EZKIT-Rel1.0.0\21469_EZ-Board\Examples\Device_Programmer\parallel\21469_m29w320_dpia.dxe

    2) Please confirm if you have modified the driver file that you used above. Just wondering how it shows the DevCode, ManCode and all stuffs?

    Best Regards,
