TI中文支持网Part Number:TDA4VM
When I want to add a new target kernel on the tda4vm development board, in addition to the PC cross compilation method provided by Ti, we try to refer to the test demo in edgeai-tiovx-kernel and directly add and compile a new kernel on tda4vm (not on PC, not cross compile). Although it can be registered and compiled on TIVX_TARGET_A72, when I change to another target (such as DSP), the compilation can be completed, When using the setNodeTagret function to set a node on the kernel, it always reminds me "the target id is invalid". I would like to ask if this method of compiling and registering directly on the development board is not feasible? Or the method is feasible, but i need some modification about my code? Thanks for your answering.

Compiling and registering a new kernel directly on the TDA4VM development board is feasible, but there are a few considerations and modifications you may need to make in your code:
1. Verify target support: Ensure that the target you are switching to (e.g., DSP) is supported by the TDA4VM development board. Some targets may have specific requirements or limitations,
2. Kernel configuration: When compiling the kernel for a specific target, you need to configure the build system to generate the appropriate target-specific code and binaries. This may involve modifying the Makefile or build configuration files to specify the target architecture and compiler flags.
3. Node target assignment: When using the `setNodeTarget` function, make sure you are passing the correct target ID for the desired target. Each target has a unique ID, and if you provide an invalid or unsupported target ID, you will encounter the "target id is invalid" error.
4. Kernel compatibility: Ensure that the kernel you are trying to add and compile is compatible with the TDA4VM board's hardware and software environment. Incompatible or unsupported kernel code may lead to errors or unexpected behavior.
5. Debugging and troubleshooting: If you encounter issues during compilation or runtime, it's important to debug and troubleshoot the problem. Check the compiler and linker output for any error messages,
It's worth noting that the approach of compiling and registering a new kernel directly on the development board may have additional complexities compared to cross-compiling on a PC. However, with careful configuration and modifications, it is possible to add and use new kernels on the TDA4VM board.
