ECE497 Notes on DSP via c6run

Here are some notes on how to get c6run going on the BeagleBoard.

from here
This, [[Media:C6run_m_yoder.tgz]], contains the following:


 * 1) /lib/modules from target FS
 * 2) uImage itself
 * 3) C6Run package prebuilt for the above
 * 4) C6Run target software
 * 5) Kernel modules for TI components
 * 6) loadmodules.sh and unloadmodules.sh
 * 7) pre-compiled test and and example applications

from elsewhere

 * DSP toolchain - point them to same one using
 * Angstrom distribution ARM compiler
 * DSP/BIOS 5.41 - point them to same one using

Instructions for Host Setup and Build

 * Download the TI C6000 v7.0.4 code generation tools for Linux from here
 * Install the codegen tools to  (you implicitly accept a EULA when doing this)

host$ mkdir ~/toolchains host$ chmod +x ti_cgt_c6000_7.0.4_setup_linux_x86.bin host$ ./ti_cgt_c6000_7.0.4_setup_linux_x86.bin --installto ~/toolchains --mode silent


 * Download the angstrom ARM toolchain from here.

host$ tar -C ~/toolchains -xjf angstrom-2010.4-test-20100422-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.2.tar.bz2
 * Install the ARM toolchain

The ARM toolchain will be in


 * Download the 5.41.09.34 DSP/Bios package from here.

host$ chmod +x bios_setuplinux_5_41_09_34.bin host$ ./bios_setuplinux_5_41_09_34.bin --mode silent --prefix ~/toolchains
 * Install the DSP/Bios package (you implicitly accept a EULA when doing this)

host$ tar -C ~/toolchains -xzf c6run_0_95_02_02_beagleboard.tar.gz
 * Install the pre-built C6Run package

host$ cd ~/toolchains/c6run_0_95_02_02_beagleboard host$ vi environment.sh
 * Edit the c6run enviroment settings to correctly point to the location of the components on your host PC (replace ${HOME} with the absolute path)

host$ source environment.sh
 * Source the environment variables

A this point the enviroment and components are all setup to build the examples and test cases included in the the C6Run package. All the makefiles for the examples and test cases rely on FOUR environment variables: ARM_TOOLCHAIN_PREFIX, ARM_TOOLCHAIN_PATH, CFLAGS, and C6RUN_TOOLCHAIN_PATH. The compilation scripts (c6runlib and c6runapp scripts) rely on these and the other variables from the environment.sh file.

It is suggested that the test and example makefiles be used as a template for any builds done for your own code.

Target Preparation

 * 1) Setup the beagleboard to boot using the included kernel image (uImage binary file). This should just require replacing the uImage file on your SD card with the provided one (rename the file to be just ' ').
 * 2) Copy the the contents of the provided   to the target's   path. I found I didn't need to do this.
 * 3) Copy the contents of c6run_target.tar.gz to the target file system.  I place it in  . It contains the kernel modules form the TI components and the loadmodules.sh script which should be used to install them.  The pre-built examples and test cases are also included in this archive
 * 4) Before running any c6run based application, make sure you run the loadmodules.sh script to load the needed kernel modules.
