Here's what I did:
1. Install FreeBasic compiler in BBB 1.1. Download package from http://www.freebasic-portal.de/downloads/fb-on-arm/bbb-fbc-fbc-fuer-beaglebone-black-283.html wget http://www.freebasic-portal.de/dlfiles/452/bbb_fbc-0.0.2.tar.xz 1.2. Uncompress and copy files cd bbb_fbc-0.0.2 cp usr/local/bin/fbc /usr/local/bin/ cp -R usr/local/lib/freebasic /usr/local/lib/ 2. Install pruss driver kit for freebasic and BBB. 2.1. Download and uncompress package from http://www.freebasic-portal.de/dlfiles/539/FB_prussdrv-0.0.tar.bz2 2.2. Copy files cd FB_prussdrv-0.0 cp bin/libprussdrv.* /usr/local/lib ldconfig mkdir /usr/local/include/freebasic/BBB cp include/* /usr/local/include/freebasic/BBB cp bin/pasm/usr/local/bin cp bin/PRUSSDRV-00A0.dtbo /lib/firmware 2.3. Install am335x-pru-package apt-get install am335x-pru-package 2.4. Activate the PRUSS by enabling the tree overlay. This must be done everytime, after each boot or before running your programs. echo PRUSSDRV> /sys/devices/bone_capemgr.9/slots 3. Install libpruio 3.1. Download and uncompress package from http://www.freebasic-portal.de/dlfiles/554/libpruio-0.0.2.tar.bz2 3.2. Copy files cd libpruio-0.0.2 cd src/c_wrapper/ cp libpruio.so /usr/local/lib cp libpruio.a /usr/local/lib ldconfig cd ../pruio/ cp pruio.bi /usr/local/include/freebasic/BBB cp pruio.hp /usr/local/include/freebasic/BBB cp pruio_pins.bi /usr/local/include/freebasic/BBB 4. Here's a simple example C program that uses the library #include <stdio.h> #include <unistd.h> #include "pruio_c_wrapper.h" #include "pruio_pins.h" int main(int argc, const char *argv[]) { PruIo *io = pruio_new(0, 0x98, 0, 1); if (io->Errr) { printf("Initialisation failed (%s)\n", io->Errr); return 1; } if(pruio_config(io, 0, 0x1FE, 0, 4, 0)){ printf("Config failed (%s)\n", io->Errr); return 1; } int a = 0; int i; while(1){ printf("\r%12o %12o %12o %12o %4X %4X %4X %4X %4X %4X %4X %4X\n", io->Gpio[0].Stat, io->Gpio[1].Stat, io->Gpio[2].Stat, io->Gpio[3].Stat, io->Value[1], io->Value[2], io->Value[3], io->Value[4], io->Value[5], io->Value[6], io->Value[7], io->Value[8]); fflush(STDIN_FILENO); usleep(1000); } pruio_destroy(io); return 0; } 5. To compile it, here's a makefile: all: bbb-io.c Makefile gcc -Wall -o bbb-io bbb-io.c /usr/local/lib/freebasic/fbrt0.o -lpruio -L"/usr/local/lib/freebasic/" -lfb -lpthread -lprussdrv -ltermcap -lsupc++ -Wno-unused-variable -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
