Embedded Target for TI C2000 TMS320 Platform DSP Known Software and Documentation Problems

This document describes important known software and documentation problems. Click on a problem area listed below for details.

Compiler Optimization Setting
Internal Memory Map Option Not Supported for LF2407
Simulation and Code-Generation Differ for DMC Library PID Block
Simulation Stop Time Not Honored for Multitasking Models Using ERT Mode

Compiler Optimization Setting

For some blocks, when the C24x or C28x compiler optimization is set to -o2, the results from target execution of generated code may not match the results from simulation. In these cases, changing the optimization by setting it to one of the lower settings (None or -o1) removes the discrepancies.

Internal Memory Map Option Not Supported for LF2407

Selecting Internal_memory_map in the Target Preferences block for LF2407 generates a Full_memory_map linker command file. This is because Internal_memory_map is currently not supported for the LF2407.

Simulation and Code-Generation Differ for DMC Library PID Block

At high values of the mask parameters, simulation code and generated code may differ. This is a result of down-casting to the single-precision floating-point data type used for entering mask parameters. The generated code represents the parameter values exactly, while the simulation code represents the parameter values with decreased precision.

Simulation Stop Time Not Honored for Multitasking Models Using ERT Mode

The Simulink simulation stop time is not honored in code generated for a multitasking model when ERT-based code generation is used.
