=======

C Library for the BeagleBone (Black) Programmable Realtime Unit SubSystem

###Compiling App Loader

    git clone https://github.com/BeaglePilot/PRUSS-C.git

    cd PRUSS-C/am335x_pru_package/ pru_sw/app_loader/interface

    make

    cd ../lib

    scp libprussdrv.so [email protected]:/usr/local/lib

    

###Basic Command for Compilation

You can find an example blinkled PRU code @ `PRUSS-C/am335x_pru_package/pru_sw/example_apps/blinkled/blinkled_pru.c`

####for 64-bit systems only:    

    sudo apt-get install ia32-libs-multiarch

####else for 32-bit systems start from here 

######for x86_64/i686

    export PRU_C_DIR="/opt/ti/PRUCGT1.0.0B1/include;/opt/ti/PRUCGT1.0.0B1/lib"

    export PATH="/opt/ti/PRUCGT1.0.0B1/bin;/opt/ti/PRUCGT1.0.0B1/;/opt/ti/PRUCGT1.0.0B1/example":$PATH

    clpru --silicon_version=3 -o1 blinkled_pru.c -z AM3359_PRU.cmd -o PRU_tests.out -m PRU_tests.map

    hexpru bin.cmd PRU_tests.out

This generates 2 files: data.bin (containing the data sections) and text.bin (containing the .text sections).

######for arm systems

    export PRU_C_DIR="/path/to/ARMLinuxA8/include;/path/to/ARMLinuxA8/lib"

    export PATH="/path/to/ARMLinuxA8/bin:/path/to/ARMLinuxA8/:/path/to/ARMLinuxA8/example":$PATH

    clpru --silicon_version=3 -o1 blinkled_pru.c -z /path/to/ARMLinuxA8/AM3359_PRU.cmd -o PRU_tests.out -m PRU_tests.map

    hexpru /path/to/ARMLinuxA8/bin.cmd PRU_tests.out

This generates 2 files: `data.bin` (containing the data sections) and `text.bin` (containing the instruction sections).

###Compiling PRU source code with StarterWare driver library

Examples included inside the PRUSS_LIB :- blinkled

    cd PRUSS_C/PRUSS_LIB/

    export PRU_BASE_PATH=path/to/PRUSS_LIB

    export PATH="/path/to/ARMLinuxA8/bin:/path/to/ARMLinuxA8/":$PATH

    cp path/to/ARMLinuxA8 path/to/PRUSS_LIB

    cd example

    make

This generates 2 files: `build/data.bin` (containing the data sections) and `build/text.bin` (containing the instruction sections).

###Compiling your BBB main app

#####Example blinkled:

    cd PRUSS-C/am335x_pru_package/pru_sw/example_apps/

    make

    cd bin/

    scp blinkled [email protected]:~/

###Executing your Application on BBB

Copy data.bin and text.bin to the same folder as blinkled application.

Note:follow the steps in the shown order

    export LD_LIBRARY_PATH=/usr/local/lib

    modprobe uio_pruss

Create BB-PRU-00A0.dts with contents as shown @ http://hipstercircuits.com/category/pru/ and load the cape using capemgr.

and finally

    

    ./blinkled

you should see two LEDs blinking
