A quick, easy, hassle-free DVSDK setup.
This guide is adapted from this blog post, which is more verbose.
If this guide doesn't answer your questions, read that as well.
According to TI's Getting Started Guide: OMAP35x DVEVM Software Setup, you'll need the following packages:
- dvsdk_3_01_00_10_Setup.bin - source for
cmem,dsplink,lpm,sdma, etc - TI-C6x-CGT-v6.1.12.bin - DSP compiler
- data_dvsdk_3_01_00_10.tar.gz (direct link) - example files to run demos on
- cs1omap3530_setupLinux_1_01_00-prebuilt-dvsdk3.01.00.10.bin
- AM35x-OMAP35x-PSP-SDK-03.00.01.06.tgz - root file system
- Documentation found in
AM35x-OMAP35x-PSP-SDK-##.##.##.##/docs/omap3530/UserGuide-##.##.##.##.pdf, once extracted. - This is similar to the OpenEmedded
omap3-console-image, but for TI's EVM board.
- Documentation found in
- codesoucery_tools (direct link) - compiler toolchain
- This is TI's partner's version of OpenEmbedded's
gcc-crosswhich containsarm-none-gnueabi-gccand friends.
- This is TI's partner's version of OpenEmbedded's
For compiling code which uses the DSP intrinsics you'll need dsplib64plus, dsplib64plus.h, dsplib64plus.lib
- C64x+ DSP Library (DSPLIB) (direct link)
- How to include this library in a project
I'll assume that you've downloaded the above to ~/Downloads and that you accept the default paths
DVSDKDIR=~/dvsdk
cd ~/Downloads
# Accept the defaults
./dvsdk_3_01_00_10_Setup.bin --mode console --prefix ${DVSDKDIR}
./cs1omap3530_setupLinux_1_01_00-prebuilt-dvsdk3.01.00.10.bin --mode console --prefix ${DVSDKDIR}/dvsdk_3_01_00_10
sudo ./ti_cgt_c6000_6.1.12_setup_linux_x86.bin --mode console
echo 'export C6000_C_DIR=/opt/TI/C6000CGT6.1.12/include:/opt/TI/C6000CGT6.1.12/lib' >> ~/.bashrc
echo 'export C6X_C_DIR=${C6000_C_DIR}' >> ~/.bashrc
source ~/.bashrc
Although CSTOOL_PREFIX should allow you to change your toolchain prefix, it's hard coded to arm-none-linux-gnueabi in some places.
If your compiler toolchain uses a different prefix you will need to link it to the name TI's tools expect.
Example (Overo on OpenEmbedded):
cd ${OVEROTOP}/tmp/sysroots/i686-linux/usr/armv7a/bin
ls | cut -d'-' -f5-99 | while read COMP
do
ln -s arm-angstrom-linux-gnueabi-${COMP} arm-none-linux-gnueabi-${COMP}
done
You can overlay the dvsdk with this repository
cd ~/dvsdk/dvsdk_3_01_00_10
git init
git remote add fastr git://github.com/fastr/ti-dvsdk-3-overlay.git
git fetch fastr
git checkout overo -f
Which essentially makes these changes:
~/dvsdk/dvsdk_3_01_00_10/Rules.make
* `DVSDK_INSTALL_DIR=$(HOME)/dvsdk/dvsdk_3_01_00_10`
* `CODEGEN_INSTALL_DIR=/opt/TI/C6000CGT6.1.12`
* `OMAP3503_SDK_INSTALL_DIR=$(HOME)/AM35x-OMAP35x-PSP-SDK-03.00.01.06`
* `CSTOOL_DIR=$(HOME)/CodeSourcery/Sourcery_G++_Lite`
* `CSTOOL_PREFIX=$(CSTOOL_DIR)/bin/arm-angstrom-linux-gnueabi-`
cd ~/dvsdk/dvsdk_3_01_00_10
