binaries on linux bsp

Board : bsc9131rdb

U-Boot : Poky (Yocto Project Reference Distro) 1.6

attempt to run ipc_integration demo from demos included with CW 10.5.2 Starcore

root@bsc9131rdb:~# ./ipc_9x31_dbg.bin

-sh: ./ipc_9x31_dbg.bin: cannot execute binary file: Exec format error

The readme for this demo says "execution can be done only through Linux console". I do see "-arch psc9131" appended to the arguments used to call psc913x_bin_creator.exe. I have also tried run other binaries that were created using the psc9131x_bin_creator (left the post-build step included w/ the demos unaltered) with the same error.

Did you load the image with dsp_bt?

I am using the prebuilt images. For the ramdisk image, name is fsl-image-core-bsc9131rdb-20140610221219.rootfs.ext2.gz.u-boot

I believe the fsl-image-core has the necessary libraries in. Description in help is "This is a small image somewhat like “fsl-image-minimal” except It contains all of the Freescale-specific SDK packages such as USDPAA, etc."

Is there a quick way I can check if my ramdisk image has dsp_bt?

I get the same error for other demos as well (not ipc related..) as I mentioned before in my 1st post.

I have determined that my original image that I was using lacked ipc, but that was not the cause for the issue at hand. For some demos, I see messages like

$ ./basic_demo_9x31.bin: line 3: syntax error: unexpected ")"

which seems to say that my .bin is compiled for something else?

psc913x_bin_creator.exe makes a call to SC\StarCore_Support\compiler\bin\sc100-elf2xx.exe to make the .bin from the eld

The user guide for loading DSP images from Linux can be found here: Freescale Technical Information Center

To build the necessary Linux modules / apps (dsp_bt, ipc_test) you can use yocto (they are included in fsl-image-full, if you've already this rootfs).

Hope this helps

In the BSC9131 quick start guide,

Doc Number: BSC9131RDBQSG REV 0

On page 10, it seems to imply that I should not be using dsp_bt. I also compared the documentation for the IPC demo w/ codewarrior 10.6 (b4860) and 10.7 (psc913x) and it seems the instructions for loading w/ dsp_bt are on 10.6 but not on 10.7. Is there something I am missing?

Documentation on loading the DSP from Linux and running the ipc test is in the infocenter. Were you able to open the link?

In SDOS demos, ipc_integration is to be run using dsp_bt (see infocenter) and ipc_demo_sc_only is to be run using CW for SC only.

Thanks for clearing that up. So SDOS binaries can only be run on BSP through dsp_bt?

I am not aware of other ways so far.

Hi, I confirm that this is the only way to boot SDOS from Linux.

Also please use WUSDK1.5 release, DSP_BT is not supported for 913x on SDK1.6.

See here the feature support：
