About booting the DSP side of bsc9131

Hi,

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

.....

What's wrong with that?

Hi

So this seems to be a misinterpretation: dsp_bt is a program which is used to load the DSP code and set it to run. It's usage is typically:

dsp_bt <dsp binary image.bin>

the example is just showing the paths to find each part (the bootloader program and the dsp binary image)...

Once this is done you should run the ipc_test application as this will be the Linux side application that sends and receives IPC messages (which the DSP binary image should also do).

And what's more,if I excecute dsp_bt,the result is

===DSP boot Application===(1.1.02)==

Usage:

dsp_boot

but it seems like there is something wrong,just like the doc says,

Appearance of ‘DSP Booted up’ confirms successful completion of DSP firmware upload.

Thanks,so what should I do now to run the DSP side(which is the Linux side send and receives IPC messages to DPS side)?
