          I'm following the Using PSC9131RDB BSP,A step by step guide to boot the DSP side of 9131,but now I get some questions,the guide says like below,

          Required binary images are already part of rootfs. The release contains a test firmware that is used to verify IPC function. To load this firmware on DSP, execute following command on Linux shell prompt: $ /ipc/dsp_bt /dsp_images/ipc_913x_dbg_0.5.bin

          but in my 9131's linux OS,the dsp_bt is a file instead of a directory,

          root@bsc913x:/ipc# ls -l

          -rwxr-x---    1 root     root          8441 Jun  7  2013 app

          -rwx------    1 root     root          8621 Jan 28  2014 dsp_bt

          -rwxr-x---    1 root     root          8329 Jan 28  2014 dsp_recover

          -rwx------    1 root     root          7538 Jan 28  2014 dump_mem

          -rwx------    1 root     root         11779 Jan 28  2014 ipc_test

          -rwx------    1 root     root         11312 Jan 28  2014 ipc_test67

          -rw-r--r--    1 root     root            34 Feb 21  2013 mem_dump_cfg.txt


          and if I just excute the ipc_test in the ipc dir,the endless log appears:

          main loop #ret  0

          main loop #ret  0

          main loop #ret  0


          What's wrong with that?
