C6748 Development Ket (LCDK)

Other Parts Discussed in Thread: SYSBIOS

Hi,

I have an application that was developed to run on the L-138 SDK .   I have ported the application to run on the C6748 LCDK.  I can load and run the application from the debugger but cannot run from flash.  Was wondering if there is some obvious reason why the application will not run from flash.   I noticed that the sysbios demos available are running on version 6.33.1.25(6.35.4.50).  Does the C6748 LCDK support previous versions of sysbios?  Currently running on version 5x.  I reduced main to a while(1) loop and the code never gets there.  Appears that the application is never being called.   Any way to verify what is executing and what is actually running?  If I connect the debugger the addresses present are not in the memory map.  Any suggestions or help would be appreciated.

  • Hi Steven,

    I've forwarded this to the software team. Their feedback should be posted here.

  • Steven,

    In order to boot the application, you need to convert the application to AIS formatted binary. Please indicate if you have done this and were able to flash the application to the NAND flash on the LCDK using the serial flashing and boot tools.

    One thing to watch out for when you are loading SYSBIOS application is the entry point for the application as indicated here:

  • Steven,

    A common cause of problems like what you have is that the default GEL file initializes things on the device and the board, but those have not been implemented in your boot process. Some of these things can be done in the AIS format, but there might be things that are not implemented anywhere in the Flash code.

    Check your boot mode.

    From CCS, clear all internal and external memory. Reset the device so it will boot from Flash, then try to Connect to the DSP and halt it. Take a look at the memory areas that should have been loaded by the Flash file and see if anything was loaded.
