TMS320F280049: An image for bootloader (kernels), application and DCSM

Part Number: TMS320F280049
Other Parts Discussed in Thread: UNIFLASH

Dear Champs,

I am asking this for a customer.

They use a bootloader/kernel project, an application project with DCSM/passwords generated by the DCSM GUI.

Because there are two CCS projects, there are two corresponding output files (.out).

Now, they want to program these two .out images once in the production line.

That is, they wonder how they can use one image to program these by the operator just for one time.

Do you have any suggestion how they can do this?

Does it make sense they program F280049 with these two projects (.out files) separately on the engineer's side first and then use Uniflash to unlock F280049 and read out all flash and OTP contents and then save it into a new .out file as an image?

    Hi Wayne,

    There are two options:

    1) Yes, program and then unlock.  There is a "save memory" option in the memory window.  In below snapshot, you can see the "Add Range" button.  Multiple ranges can be added as needed.

    2) For info on merging the .out files, please take a look at the the sub-chapter titled The Load Image Format in C28x assembly tools manual.

    They can use hex tool to combine the images - Something like this:  hex2000 --load_image -o combined.out prog1.out prog2.out    

    We can ask our compiler/SDTO teams if you need further info.

    Thanks and regards,
    Vamsi
