Hi everyone.
I am using a DM8168 board,
and my sdk version is
dm8168_ezsdk_5_02_02_60 ( omx_05_02_00_15, syslink_2_00_02_80 , c6run_0_98_00_00 )
Q1
When I run a program which is using openMax and C6run.
I got syslink errors like below:
-----------------------------------------------------------------------------------
Assertion at Line no: 1737 in /swcoe/sdk/cm/netra/arago-tmp/work/dm816x-evm-non

utils/hlos/knl/Linux/../../../../../../ti/syslink/ipc/hlos/knl/MessageQ.c: (Mes

What is the error mean?
Q2
openMax program and c6runLib program work fine respectively,
but program will stop at OMX_deinit() function.
(I found it stopped at syslink_destroy() be called, why)
When I use Ctrl+C to kill that process, message showed like below
-----------------------------------------------------------------------------------

Can anyone give me some advises about these problems?
Any opinions will be greatly appreciated.
