I have got some audio codecs from this link:
software-dl.ti.com/.../index_FDS.html
I also need AAC codec for C66 DSP on AM5728.
I try to use AAC codec for C674X DSP on DM8168 from DVR_RDK packages.
But I meet fatal error after processing almost 364 or 366 audio frame data(48KHz 1024 samples per-frame).
The error messages are like these:

If I just process 363 audio frames(48K 1024 samples per frame), there isn't any error and the result are correct.
I have no idea to find the root cause. Maybe it was something about DSP's stack or the AAC codec from DM8168 isn't suit for for am5728.
Any help will be appreciated.
