As of right now, we don't officially support the MCSDK libraries from TI. Using Ubuntu, I was able to download and install the tools as directed by TI. After that, I was able to build the linux kernel 3.3 using the files and instructions provided by TI's MCSDK and successfully boot it off an SD card, but it is highly untested - including the DSP.

The instructions I used were provided by TI here: http://processors.wiki.ti..._Started#Program_EVM


I would suggest that if you are interested in pursuing development with TI's MCSDK, we could have someone in our sales department contact you to setup a contract with our services group. They could work with you to adapt the newer TI libraries and Linux Kernel to the SOM as needed for your application.

Even after I submitted the e-mail, I wanted to see about using the replacement to DSPLINK now called SYSLINK.

The MCSDK requires a slightly newer set of Arago tools, and this document both documents some issues and how to fix them.

http://processors.wiki.ti...opment_Kit_.28PDK.29

With its changes to the TI instructions, you should be able to build both the Kernel as well as the SYSLINK to access the DSP. It also comes with some example test programs. I will post some preliminary results tomorrow when I have had a chance to install the modules and run the examples.

-adam

As a point of reference, I used the following tools:

Arago-toolchain-2011.09-armv5te-linux-gnueabi- http://software-dl.ti.com...11_09/index_FDS.html

CCSv5.4.0.00091 - http://software-dl.ti.com...dio/CCSv5/CCS_5_4_0/

MCSDK_01_01_00_02_setuplinux - http://software-dl.ti.com...test1/index_FDS.html

 

Once installed, syslink and other libraries are placed in /opt/ti

You'll need to build syslink for the new kernel.

 

 

I am successfully getting the syslink.ko driver to build, but I am not able to get the module to work correctly. At this point, I would recommend going through our services group.

-adam

Good News. It turns out that I was using the wrong rootfs. When using the correct rootfs, I was able to install the syslink kernel module with insmod and I was able to run the example tests. This environment is still highly untested, but the basic proof-of-concept seems to be functional.
