Part Number: TMS320F280049

Hi TI，

The flash size of tms320f280049 is 256Kb. The. Out file generated by CCS is larger than 256Kb, with a size of 364kb. What have we done to burn the. Out file to the device？

    Hello,

    There are several options to try to solve your code size issue:

    1. Check your optimization settings. Right click on your project and choose properties; then select Optimization under Build > C2000 Compiler in the left pane. Set your optimization level to 4, and set the --opt_for_speed setting to 0 for minimum size. In addition, you can set floating point mode to relaxed to enable use of the TMU for floating point division and other operations instead of software math lib. Note that debuggability will decrease as optimization increases, as ASM instructions may not necessarily be sequential with respect to C code.

    2. Review your code to try to reduce its size, where possible.

    3. If code optimization and compiler settings are not able to reduce your code to the needed size, consider using a device like F280039 which is quite similar to F280049 in features, but has a larger flash size (384K).

    Best regards,
