TMS570LS0232: Remove zero fill from binary file generated by CC studio

I tried making FLASH0 smaller, it still fills it with 0x00.

I tried using the ARM hex utility at the end and using the --fill 0xFF command, but it's still putting 0x00.

Hi Quentin,

Are you using "fill" in your linker cmd file:

If you are using that then please try vfill instead of fill:

Because fill will generate image for entire flash with all unused data words with 0xFFFFFFFF, this increases binary size a lot.

I am not using fill at all (look at FLASH0 below). I've reduced the length to around the size of the image, but it still fills the rest of the FLASH with 0x00 in the .hex

MEMORY
{
    START_MARKER (RX) : origin = 0x0001FFF0 length = 0x00000010
    VECTORS      (X)  : origin = 0x00020000 length = 0x00000020
    PART_NUMBER  (RX) : origin = 0x00020020 length = 0x00000060
    FLASH_API     (RX) : origin = 0x00020080 length = 0x00001480
    FLASH0       (RX) : origin = 0x00021500 length = 0x000D0000
    FLASH1       (RX) : origin = 0x00180000 length = 0x0001FFF0
    END_MARKER     (RX) : origin = 0x0019FFF0 length = 0x00000010
    STACKS       (RW) : origin = 0x08000000 length = 0x00002000
    RAM          (RW) : origin = 0x08002000 length = 0x0002D000
}

I guess I could write a script to strip those empty sectors from the hex, but I had hoped it could be done as a build option.

Also, I have ECC off, I'll try and use the vfill option in the linker.

Hi Quentin,

By any chance are you keeping below option as YES?

It was not selected. I've tried with all the above options off, and it still does it!

Is it okay to share your project with us? You can share it with private chat as well. Because i can quickly verify all the settings and see the issue lively.

If it is a confidential then we can try other way.

I cannot send the project. I mightbe able to send the .cproject file that has all the settings.

Removing this as it's not useful.

Hi Quentin,

We have several examples in below FAQ, and none of them had been filled with all zeros in empty places of the flash. So, i am suggesting you to refer them once and especially refer their linker files and project properties.

Good Work!
