Compiler/TMS320F28377D: How to generate two .bin file from one project

It is possible to direct the hex utility hex2000 to convert an executable file into multiple binary files, one file per memory range.

For background, please search the C28x assembly tools manual for the sub-chapter titled Image Mode and the --fill Option.

Add a hex utility command file to the CCS project.  Model it on this one ...

/* rom_commands.hex */

/* Presumes use of the following hex2000 options */
/* --binary  */
/* --image   */

ROMS
{
    INTERNAL_FLASH : o = 0x2000, l = 0x4000
           files = { internal_flash.bin }

    EXTERNAL_FLASH : o = 0x8000, l = 0x4000
           files = { external_flash.bin }
}

In your hex utility options in CCS, enable the options --binary and --image.  For details on adding this hex utility command file to the project, please see this forum post.

The memory ranges defined in this ROMS directive are similar to the ones in the linker command file, but with an important difference: The addresses and lengths are doubled.  For details, search the same manual for the sub-chapter titled TI-TXT Hex Format.  That sub-chapter describes why the addresses and lengths are doubled when using TI-TXT format, but it is the same for binary format.

The output of the hex utility is written to the files named for each memory range in the ROMS directive.
