Compilation of an ARM+DSP application on Rowboat Froyo for DM3730

That portion of the Makefile for ce_examples is inherited from Linux, which and the example applications are not ported to Android.

Thanks for the clarification.

Is there any other simple example ported to Android and which uses ARM+DSP?

There is nothing I am aware of. Currently there is no such JNI available for applications to use DSP.

In the youtube video "Rowboat Android on OMAP35x" (http://www.youtube.com/watch?v=AIWo1YSi6ng) we can see the application "decode" running on a development board based on OMAP35x ("DSP Accelerated Video Decode").

I can find this application under "/ti-dvsdk_dm3730-evm_4_01_00_09/dvsdk-demos_4_00_00_21/omap3530/decode", but when I try to compile it with  a modified Makefile (see below) to cross-compile with Android toolchain, I get the following error:

Linking decode from audio.o codecs.o display.o loader.o main.o speech.o video.o ../ctrl.o ../ui.o decode_config/linker.cmd..
/home/pazosn/rowboat-android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/../lib/gcc/arm-eabi/4.4.0/../../../../arm-eabi/bin/ld: crt0.o: No such file: No such file or directory
collect2: ld returned 1 exit status
make: *** [decode] Error 1

Could anybody help me to cross-compile this application for Android to launch it on a DM3730/OMAP3530 together with the server cs.x64P?

Thanks in advance!
