Dear TI contributors and engineers:
Recently I want to run the audio decode and audio encode example in omx .
I followed the userguide of omx and I got the following results:
root@dm816x-evm:/# modprobe syslink
root@dm816x-evm:/# firmware_loader 0 dm816x_c6xdsp.xe674 start

<Location of Firmware> firmware binary file
<start|stop> to start/stop the firmware
===Optional arguments===
-mmap input memory map bin file name

In the beginning I ingored the results and continue to run the audio examples.
And I found that mp3 decode example runs normally but the aac encode example can't run normally.
And here is my boot args:
bootargs=console=ttyO2,115200n8 root=/dev/nfs nfsroot=192.168.1.254:/home/hv/targetfs mem=169M rw earlyprintk notifyk.vpssm3_sva=0xBF900000 ip=dhcp rootdelay=2
