Flash Programming using Matlab generated .out file for C2000 - TMS320F28335

Karuna Mudliyar

Other Parts Discussed in Thread: TMS320F28335, UNIFLASH

Greetings ...!!!!

   I use the following for my embedded system development.

Delfino experimenter kit - TMS320F28335

Code composer studio - CCSV4

Matlab - 2011b

The issue is in programming the flash memory..!!!

I have changed the "target preference setting" in Matlab for flash programming.

Once I generate the code, the Matlab command window says  - "the build is done, but error in downloading".

I could find my .out file and load them in ccsv4.

While the programming is being loaded, i could see at the bottom left - say like a operation progress status -

       " erasing the Flash sector" - "loading the program and all"

Then I run the program and it works.The program is simple led blinking on the control card itself.

But it doesn't work once I power Off and On the controller.  

Kindly, help me out..

 

Kind Regards

Karuna

    Hi Karuna,

    Try loading the .out file using CCS Uniflash. If you still observe that the program is running from RAM then the .cmd file has be modified to running from flash configuration. (I don't know how that's done in matlab)

    I have changed the "target preference setting" in Matlab for flash programming.

    As you say, you've done flash settings in matlab; do check with Uniflash and revert.

    Regards,

    Hi Gautham,

    I tried using it, first i erased and then programmed.

    But getting the same problem, the code is not able to run once powered ON.

    Here is the content of .cmd file,

    Thanks for sharing the .cmd file.

    I have to modify/edit the memory location and allocate the sections. I think this can be done in the target preference by editing the "Memory" and "Sections" tab.

    Will revert you back.

    Kind Regards

    Hi Gautham,

    It works,

    I modified the "section" tab of target interference block in Matab, according to the file you shared.

    so, here is content of new .cmd file,
