I'm using dsplink_1_65_02_09 with following steps:  

1. Installed PERL
2. run dsplinkenv.bat uder etc\host\scripts\msdos
3. Edit dsplinkcfg.bat as below

pushd %DSPLINK%\config\bin
perl dsplinkcfg.pl %* --platform=OMAPL138 --nodsp=1 --dspcfg_0=OMAPL138GEMSHMEM --dspos_0=DSPBIOS5XX --gppos=WINCE --comps=ponslrmc
popd

1. Build by running dsp\src\make

Can any experts help me? Thank you very much
