DSP/BIOS revision recommendation to run on the F2808

Other Parts Discussed in Thread: TMS320F2808

Hello,

I am trying to run DSP/BIOS 6.21.01.16 on the TMS320F2808 using CCS 4.1.1.00014. I have spent more than a week getting familiar with the process of building a RTSC project to find that I could not fit enough of the BIOS into flash for it to run. There certainly is not enough RAM on this chip to run any examples.

Is this a futile path?

Do you have any example projects that run the DSP/BIOS 6.21.01.16 out of flash and RAM for the F2808?

I just found the a link to SPRA958H, but I do not want to spend more time on this development path if it is going to be futile.

 

Thank you,

 

James

    Hi James,

    The flash memory on this device should typically be big enough to fit a BIOS 6.21 application.  I was able to build a basic BIOS application after creating a custom 2808 Platform using the following memory allocation:

    codeMemory - "FLASH", dataMemory - "H0SARAM", stackMemory - "LSARAM"

    Of course, depending on the complexity of your BIOS application, you might actually need more than the available flash memory.

    Did you get a linker failure when building your application?  Are you certain that you have placed code/data in the FLASH memory segment?  You can check your applications usage of the various F2808 memory sections by referring to your application's .map file that is generated while building  the project.  At the top of the .map file you will see a table describing memory usage.  If configured correctly you could see a memory configuration similar to the one below.  Also, please refer to the BIOS Users Guide, Appendix D for information on how to reduce your application's footprint, if you find that it is necessary to undertake this extra step.

    Regards,
