| 1 | * todo |
| 2 | * add hostname and user in image type configuration |
| 3 | * mdns avahi zeroconf bonjour not work? maybe wrong hostname |
| 4 | * confirm that the only real problem was incorrect user and hostname |
| 5 | * maybe http://elinux.org/RPi_Advanced_Setup search 'avahi' |
| 6 | * also https://stackoverflow.com/questions/10537816/cannot-connect-to-beaglebone-local |
| 7 | * set time on beagleboard based on host system time |
| 8 | * set timezone on beagleboard based on host system timezone |
| 9 | * get network up and running, share network through host system |
| 10 | * do this during bbb boot |
| 11 | * make a ~/bin dir, add it to path |
| 12 | * add full-update.bash to ~/bin |
| 13 | * initial setup on beaglebone should do |
| 14 | * sudo aptitude install -y v4l-utils # for v4l2-ctl |
| 15 | * sudo aptitude install pkg-config # for compiling |
| 16 | * for opencv: |
| 17 | * sudo aptitude install -y libopencv-dev |
| 18 | * check whether libopencv-dev is the only package necessary |
| 19 | * add ssh key to bbb image to make sshing easier |
| 20 | ** trying to compile grabber.c from derek molloy |
| 21 | *** problem |
| 22 | **** what i did |
| 23 | gcc -O2 -Wall `pkg-config --cflags --libs libv4l2` grabber.c -o grabber |
| 24 | |
| 25 | **** what i expected |
| 26 | compilation finishes and i can run grabber |
| 27 | |
| 28 | **** what actually happened |
| 29 | Package libv4l2 was not found in the pkg-config search path. |
| 30 | |
| 31 | **** potential solution |
| 32 | sudo aptitude install -y libv4l-dev |
| 33 | |
| 34 | ***** did it work? |
| 35 | * retrying compile |
| 36 | * compile finished, created grabber! |
| 37 | |
| 38 | ** another problem, getting image from camera failed |
| 39 | *** problem |
| 40 | **** what i did |
| 41 | after compiling grabber, tried to run it |
| 42 | |
| 43 | **** what i expected |
| 44 | grab images and maybe there would be a picture in the current directory |
| 45 | |
| 46 | **** what actually happened |
| 47 | grabber ran for a bit and output the following: |
| 48 | |
| 49 | "Warning: driver is sending image at 1280x720" |
| 50 | |
| 51 | after waiting for a bit, killed grabber with C-c. no picture in the |
| 52 | current directory |
| 53 | |
| 54 | **** possible solution |
| 55 | * read source of grabber.c and look for anything out of |
| 56 | ordinary. |
| 57 | * saw that frame size was hard coded to 1920x1080 |
| 58 | * redid code to 640x480. recompiled the code |
| 59 | * ran it, got no terminal output |
| 60 | * killed it with C-c after a bit |
| 61 | * saw grabber000.ppm |
