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
