Hi experts,
I download software from http://software-dl.ti.com/processor-sw/esd/PROCESSOR-SDK-LINUX-AM57X/latest/index_FDS.html , and try something below.
The result is different from http://processors.wiki.ti.com/index.php/Processor_Training:_Multimedia

I have try following, and it looks weird due to lack of rpmsg-dce-dsp..
root@am57xx-evm:~# ls -l /dev/rpmsg-dce*
crw-rw---- 1 root tisdk 248, 0 Jan 1 1970 /dev/rpmsg-dce
root@am57xx-evm:~#
Is there anything I misunderstand ??
Thanks
