Hello everyone !

We are working in the DSP algorithm but dont know where the file ae674 come from.

We have the lib but how to change the .lib to .ae674 by CCS?

Could someone give me some suggestions?

    Hi Kunlong,

    Regarding DM814x EZSDK, the ".ae674" file is named dm81xx_c6xdsp_debug.xe674 (or dm814x_c6xdsp.xe674).

    Please refer to the below links for more info:

    http://processors.wiki.ti.com/index.php/MP3_Decoder_Integration_in_EZSDK

    The pre-built DSP binary & A8 IL Client does not support MP3 Decoder. The steps mentioned in this article needs to be followed to add MP3 & decode MP3 files. The pre-built dsp binary is available at /usr/share/ti/ti-media-controller-utils/*.xe674 in the EZSDK.

    host $ make omx

    8. The following DSP and A8 side binaries are rebuilt as a result of 5 above - 

    $EZSDK/component-sources/omx_xx_yy_zz_bb/bin/dm81xx/bin/ti814x-evm/dm81xx_c6xdsp_debug.xe674

    9. Rename the DSP binary to match the names on the target filesystem as shown below

    For DM814x, rename to dm814x_c6xdsp.xe674
