AM2754-Q1: Ask for Library Generation Method based on AM275 C75 Core

Hi Zhou,

I have created a version of the custom module which support windows build. Here is the summary of changes for your reference:                                                
The source/ directory contains the generic C implementations of the tutorial audio modules — these are platform-agnostic and work across any target. The source-bsp/ directory is kept deliberately separate as a C7x-only build space. It starts with the same source code as source/, but the intent is that this is where you integrate TI C7x-specific work — whether that's swapping in DSPLIB kernels for accelerated processing, writing custom C7x intrinsics. By keeping it separate, the generic source stays clean and untouched, and the C7x optimisations live in their own space without affecting other platform builds.

Changes Made
                                                                                                                                                                                              
source-bsp/ (new) — Contains the five module source files, currently identical to source/, ready to be progressively optimised for C7x. The directory includes ti_c7x_linux.cmake and ti_c7x_windows.cmake for cross-compiling from either host, cmake/utils.cmake, xlibExtProjConfig.json for referencing external libraries like DSPLIB, and a CMakeLists.txt that handles SOC selection (AM275x, AM62Dx, AM62Ax) and automatically picks the right toolchain based on the host OS.
                                                                                                                                                                                              
include/Targets/c7x/ (new) — One thin header per module that forwards to the generic header. When C7x-specific optimisations are introduced in source-bsp/ — for example using DSPLIB deinterleave/interleave or custom instance fields for DSPLIB handles — the struct definitions can be extended here without touching the shared headers.
                                                                                                                                                                                              
include/FractMath.h (one-line change) — Added || defined(__C7000__) to the existing _TMS320C6X platform guard. The cl7x compiler defines __C7000__ but not _TMS320C6X, so fract16/32/64 types used internally by the framework header were left undefined on C7x builds.

  Make sure ti-cgt-c7000_5.0.0.LTS is installed under C:\ti\. From PowerShell in the tutorial_module directory:
                                                                                                                                                                                              
  cmake -G Ninja -DSOC=am275x -B build source-bsp
  cmake --build build                                                                                                                                                                         
                                                                 
  Swap am275x for am62dx or am62ax as needed. To override the toolchain path:                                                                                                                 
                                                                 
  cmake -G Ninja -DSOC=am275x -DCGT7X_ROOT="D:/ti/ti-cgt-c7000_5.0.0.LTS" -B build source-bsp                                                                                                 
  cmake --build build      

Let me know if you run into any more issues.
