TMS320F280025C: Unable to pad and align after processing hex data

Green Deng

Part Number: TMS320F280025C

Dear team:

Due to hardware problems, customers can only program through C2Prog.

After my client added the sincos function to the project, he found that the program could not be programmed with C2Prog, and an error occurred:

Unable to pad and align after processing hex data

There is no problem in programming with C2Prog without calling the sincos function.

The program code is as follows:

May I ask what could be the cause?

Hi Green,

Question: If the FPUmathTables are in ROM, why did not they make it as TYPE = NOLOAD?

Note that F280025C has TMU. Please take a look at this post: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/626783/ccs-tms320f28075-calculation-error-when-use-sincos-function

If they mapped this function to flash: Where is this function mapped to in the flash? Is that section in the linker cmd file aligned to 128-bit boundary using ALIGN(8)? Can the user provide their map file and the linker cmd file?

Thanks and regards,
Vamsi
