    Hi, Additional information on DVSDK (of which DSP LINK is a part) for WinCE/OMAP3530 and download links can be found here. http://focus.ti.com/docs/toolsw/folders/print/dvsdk-winceomap.html . Please note though that this has only been verified with bSquare BSP and Mistral EVM. Jatin

    You will need to edit the dsplink\make\current.mak to copy the headers/libs to your desired location. For headers, search for $(EXP_HEADERS) rule in this file and add the copy command for your desired location. For libs, search $(export_deb) and $(export_deb) in this file and add your copy commands here...

    Loading a DSPLink DSP-side application (*.put) via emulator versus begin loaded via the ARM -side application using PROC call will cause the DSP application to hang. The DSP application requires some handshaking on the DSP-side when DSPlink is being uses. If you want to test your application on the...
