PRUSS-C

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 root@beaglebone.local:/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 root@beaglebone.local:~/ ###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
