CCS/TMS320F28069M: HEX Utility Question

Javier Vara

Tool/software: Code Composer Studio

Hello,

I currently have a program and I am using the HEX utility to generate a .hex file that my bootloader uses to flash the microcontroller. All of this works ok.

Now, I would like to be able to use the same bootloader to flash an entire sector (Sector H) with calibration tables. Currently when I compile the program using CCS a get a .hex file with all of the program. I would like to have two .hex files output. One with the main program and another one that simply contains all of the calibration tables in flash sector H. I have been reading through the compiler manual and searching for posts in the forum and couldn't find anything like it. Any idea about how to do this?

I think I can force the linker to place the calibration tables in sector H by using:

#pragma DATA_SECTION(Calibration_Table1, "Calibration_Tables")

However I still get a single .hex file. This calibration tables are simply big matrices (45x45 float).

Javier,

Hextool outputs two different hex files (page0 and page1). Do you have this table mapped to page1?

If not, try to allocate it alone to page1 and see if you can separate it that way.

I will assign this to our compiler team so that they can guide you further.

Thanks and regards,

Please search the C28x assembly tools manual for the sub-chapter titled The ROMS Directive. You can use the ROMS directive to limit the output to just part of the system. Thus you could solve your problem by running the hex utility two different times, with different ROMS directives.

Thanks and regards,
