3.8.2.2 DVSDK System Demonstration
DVSDK (Digital Video Software Development Kit) is software developed by TI Company, the
function of which is to establish a connection between ARM and DSP.
The application program runs at the ARM end, and ARM processes IO interface and the
application program. ARM uses VISA APIs interface provided by Codec Engine to process video,
image and voice signals. Codec Engine then uses DSP/BIOS Link and xDIAS as well as xDM
protocol to communicate with the Codec Engine server. DSP processes these signals and puts
results of processing in the memory space shared by ARM, such that the ARM end can obtain
these results.
• The computer end has to be installed with Linux operating system in
advance; and the instruction in Step 1 is finished in PC.
• uImage_4.3 mentioned in the following context means 4.3-inch
screen; please use uImage_7 if the user uses 7-inch screen.
1) Divide the TF card into two partitions (please refer to Appendix IV for specific operation),
connect the TF card to PC, and then execute the following commands:
cp /media/cdrom/linux/demo/dvsdk/image/MLO /media/LABEL1
cp /media/cdrom/linux/demo/dvsdk/image/u-boot.bin /media/LABEL1
cp /media/cdrom/linux/demo/dvsdk/image/uImage_4.3 /media/LABEL1/uImage
rm -rf /media/LABEL2/*
sudo tar jxvf linux/demo/dvsdk/image/ dvsdk-dm37x-evm-rootfs.tar.bz2 -C
/media/LABEL2
sync
umount /media/LABEL1
umount /media/LABEL2
2) Prepare TF card, insert it in the development board, and turn the power switch on; it is
necessary to configure parameters of u-boot; the boot-up serial port information is as follows:
