Dear Sir
My customer had designed DM3730 for their Car entertainment application.
Their found sometimes DM3730 hang when it decode video media file (Like mp4 file), but audio decode is normal work.
It seems DSP hang,but I have no idea to find out root cause.
Please help me to solve this issue.
The attached file is debug message after DSP hang for you reference.
If you have any good idea for this issue, please let me know.
Thanks.
