1. Download and install VirtualBox
Version 4.3.20 used in this example.
2. Create Virtual Machine
3. Create a Name
Select OS Type and Version you will be installing:
Ubuntu (32 bit)
4. Memory Size
5. Create Virtual Hard Drive
6. VDI (VirtualBox Disk Image)
7. Dynamically Allocated
8. File Location and Size
NOTE: In addition to the OS, the EZSDK plus add-ons take up a fair amount of space.
Controller: IDE Add CD/DVD Device Choose disk ubuntu-10.04.4-desktop-1386.iso Ok
NOTE: This sets the ISO as the boot image.
1. Download VirtualBox Guest Additions ISO
NOTE: Make sure you select the version that matches the version of Virtual Box and the OS matches the guest OS.
Controller: IDE Add CD/DVD Device Choose disk VBoxGuestAdditions_4.3.20.iso Ok
NOTE: This mounts the ISO as a CD
Open a terminal
cd /media/VBoxGuestAdditions_4.3.20 sudo ./VirtualBox-4.3.20-96996-Linux_x86.run Shutdown
4. Creating a Share Folder
Create folder on host to be used as your share folder between host and guest (ie VirtualShare)
Settings Shared Folders Folder Path Browse to share folder location on Host machine Select Auto-Mount
5. Set of Copy and Paste Between Host and Guest
Advanced Shared Clipboard: Bidirectional Drag'nDrop: Bidirectional
NOTE: Share folder is located at /media/sf_VirtualShare (depends on folder name).
6. Network Setup
Attached to: Bridge Adapter Start
NOTE: System uses dash shell as /bin/sh despite echo $0 telling me bash.
sudo dpkg-reconfigure -plow dash Install as /bin/sh? ---No
sudo chmod 777 arm-2009q1-203-arm-none-linux-gnueabi.bin ./arm-2009q1-203-arm-none-linux-gnueabi.bin
NOTE: Anything may be chosen, but installed @ '/home/tim/CodeSourcery/Sourcery_G++_Lite/'
sudo chmod 777 ezsdk_dm816x-evm_5_05_02_00_setuplinux
NOTE: Should find your cross compiler automatically but if not, proceed to guide it to the '/<home/tim>/CodeSourcery/Sourcery_G++_Lite/bin' folder
3. Setup Build Path
NOTE: If Ubuntu is used you may need to first run "sudo apt-get update" to update the package lists.
4. Update files
upzip SI-EZSDK zip file.
cp the content of SI-EZSDK to ti-ezsdk dir.
Please notice that SI-EZSDK will overwrite some files of ti-ezsdk to support the customization of SI-DM816x.
The default targetfs dir generated by ti-ezsdk installation contains too many unnecessary files. Inside SI-EZSDK/filesystem, SI provides a slim version of targetfs (SI-initrd.tar.gz).
Change EXEC_DIR inside Rules.make to targetfs path (the dir that will be used as rootfs on target board) make u-boot-min: will build u-boot image to be used as first stage make u-boot: will build u-boot image to be used as second stage make test: will build Linux kernel, Linux Modules, Video in&out Demo & Rootfs
The RS-232 serial port is used to communicate with the SI-DM816x module via a host using a serial terminal program.
Pin connections on the IDC2x5 header on the SI-DM816x module are arranged to form a null modem cable, such that a simple ribbon cable may be used to connect to a standard RS-232 9 pin DSub connector. However, many motherboards no longer offer an externally accessible 9 pin DSub connector, but instead may have an IDC2x5 header on the motherboard which should allow for a direct null modem connection to the SI-DM816x using a straight ribbon cable with an IDC2x5 pin socket on each side. Please be aware to properly align polarity with pin 1 as the reference.
|Host DSub9 Connection|
|DSub9 at PC||Signal Name||IDC2x5 at DM816x|
|1||DCD <-> GND||1|
|6||DSR <-> GND||2|
|2||RxD <-> TxD||3|
|7||RTS <-> CTS||4|
|3||TxD <-> RxD||5|
|8||CTS <-> RTS||6|
|4||DTR <-> n/c||7|
|9||RI <-> n/c||8|
|5||GND <-> GND||9|
|Host IDC2x5 Connection|
|IDC2x5 at PC||Signal Name||IDC2x5 at DM816x|
|1||DCD <-> GND||1|
|2||DSR <-> GND||2|
|3||RxD <-> TxD||3|
|4||RTS <-> CTS||4|
|5||TxD <-> RxD||5|
|6||CTS <-> RTS||6|
|7||DTR <-> n/c||7|
|8||RI <-> n/c||8|
|9||GND <-> GND||9|
The RS-232 port is configured as follows:
Baud Rate: 115200 kbits/sec
Data bits: 8
Stop bits: 1
Hyperterminal is available for hosts running Win XP and earlier. However, Hyperterminal has been removed from Win 7 and later and therefore other serial port terminal programs may be used; SI recommends Tera Term. Meanwhile, hosts running Linux can use Minicom.

The program saLoopBackFbdev is used to test video IO. The source code is in $TI-EZSDK/example-applications/linux-driver-examples-psp04.04.00.01/video/. The executable is in /bin on target filesystem. When Linux is booted on DM board, type ./bin/saLoopBackFbdev on console to run the test.
NOTE: the Video I/O demos only apply to cards populated with composite video circuitry.
