Texas Instruments' Technical Tranining for students concerning the DaVinci/OMAP platforms including DM64xx, DM35x/36x, OMAP35x, OMAP-L1x, and AMx. Below are the details of the labs we'll be doing from the DaVinci workshop.
Note, the workshop calls these labs 6-8. I'm renumbering them to fit our numbering scheme, so the mapping is:
|Our Lab Number||TI Lab Number|
Labs 09/5 and 10/6 appear here and Labs 11/7 and 12/8 have their own pages.
Lab 09/5a - Instillation
- Before starting on the labs, make sure to setup the BeagleBoard DSP.
- For Lab 09b, the only required setup is the DVSDK (Linux Digital Video Software Development Kit for DaVinci Devices) and XDC Tools (eXtenDed C Tools)
- Go to the class dfs site and get
- Untar the labs file on your Linux host. It will create two directories, workshop and solutions. You will find the materials needed to do the labs below in the workshop directory. The finished product for each lab can be found in the solutions directory. The directions in DaVanci-OMAP_Workshop file will tell you which directory to use for each lab.
These labs were originally done for the Digital Video Evaluation Module (DVEVM). I've adapted them for the BeagleBoard.
Lab 09/5b - gMake
Lab 09 is lab 5 on pages 125-157 of DaVinci-OMAP_Workshop_v2.0.pdf. Work through this lab. You'll learn how make works. Part C has an error in the solution, a workaround can be found here. When you get to part D, compare my version of the make file (makefile_profile.mak.yoder) to the one in the folder. The workshop assumes you have NFS setup to share files between the DVEVM and the host computer. Rather than share files, I've set up the makefile so use sftp and ssh to copy the executables to the Beagle when installing. If you can get NFS working, great!, otherwise use my setup.
To get part d to compile correctly, you have to make sure all the path information is correct. Make sure to edit setpaths.sh, setpaths.mak, and makefile_profile.mak. Because Configuro is stubborn, you will still need to link
arm-nonearm-none-linux-gnueabi-gcc if it is to compile.
cd /home/user/CodeSourcery/Sourcery_G++_Lite/bin ln -s arm-none-linux-gnueabi-gcc arm_v5t_le-gcc
Lab 10/6 - Using the OSS Driver
Lab 10 is Lab 6 is on pages 171-186 of DaVinci-OMAP_Workshop_v2.0.pdf. In doing this lab you will get audio from the line-in jack on the Beagle and sent it out the speaker jack.
- Go to the class dfs site and get:
- Move the setpaths files in the workshop directory to another location.
host $ cd workshop host $ mv setpaths.sh setpaths.sh.orig host $ mv setpaths.mak setpaths.mak.orig
- Copy the setpaths files you got from DFS into the workshop directory. In Lab 10/6 you will edit these files so they are correct.
You will still need the symbolic link from part 5, and make sure to update the file paths.
