includes video input data to the DVO_C and DVO_D video ports and audio cascade input from a lower
cascaded stage TVP5158 device.
2.5 I2C Configuration Options
The TVP5158EVM uses one PC USB port for I2C communication. The I2C bus master can be changed
based on jumper settings. Control is via the PCB USB interface (VCC application controls TVP5158), via
the DaVinci EVM (DSP driver software controls TVP5158) or via the cascade input/output connectors J3
or J2.
2.6 Test Points and Jumpers
Various test points are available on the TVP5158EVM for the user. This includes the various power
supplies as well as a few GND test points. The user can also use J2/J3 for primary test-point headers to
access video/audio data, video/audio clocks, I2C and GND.
There are several jumpers available on the TVP5158EVM that configure I2C address select, I2C control
configuration, clock source selection and I2S source select. Each jumper is set by default in its preferred
state for the TVP5158EVM. Next to each jumper on the TVP5158EVM is the silkscreen that describes the
various jumper configurations. If the I2C address is changed on the TVP5158EVM while the
TVP5158EVM is powered up, then that device will not recognize the new I2C address. The reset button
on the TVP5158EVM must be pressed and the VCC application must be exited, restarted, and
re-configured for the new I2C address. Table 1 shows the TVP5158EVM jumper settings.

TVP5158EVM Evaluation Procedures www.ti.com
Since the DaVinci HD EVM is not packaged with the TVP5158, it is usually necessary to program its
NAND flash memory to the recommended clock frequencies, as described by the following procedure:
1. Unzip the UBL_DM646x_NAND_675_324.zip archive file onto the PC’s local hard drive.
Suggested location is C:\UBL
2. Connect a null MODEM 9-pin serial cable from the DaVinci HD EVM UART connector to the PC COM1
serial port.
3. Close any open program that is using the COM1 serial port.
4. Turn OFF the DaVinci HD EVM power switch.
5. Set SW3 Boot Mode Configuration positions 1-3 to OFF and position 4 to ON to select UART0 Flash
Boot. SW3 is located beneath the Samtec HQCD digital video ribbon cable. In the OFF position, the
switch is moved toward the PCI connector.
6. In the Windows Start menu, click Run, type cmd, and click OK to open a command window.
7. Execute these commands in the command window:
cd \ubl
sfh_DM646x.exe -nandflash UBL_DM646x_NAND_675_324.bin u-boot.bin
8. After the Waiting for the DM646x... message appears in the terminal window, turn ON the DaVinci HD
EVM power switch.
9. After flash programming has completed, turn OFF the DaVinci HD EVM power switch. Set the SW3
Boot Mode Configuration positions 1-3 to ON and position 4 to OFF to select NAND Flash boot mode.
7.2.2 Evaluation Procedure for Line-Interleaved Video Output Modes
The following are the instructions for evaluation of TVP5158 for line-interleaved modes. The digital video
output from TVP5158 is captured using a DM6467 DaVinci HD EVM and is demultiplexed and displayed
on a 1080i HD monitor.
7.2.2.1 DaVinci HD EVM Boot
1. Start the VT100 terminal application of your choice. For example, HyperTerminal can be started in
Windows XP using these steps:
(a) Click Start > All Programs > Accessories > Communications > HyperTerminal.
Set "Connect using" to:
COM1 (or other available serial port)
Set "Port Settings" to:
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
2. Turn ON the DaVinci HD EVM power switch. It may be necessary to halt the boot process (by striking
a key at the terminal) to modify boot parameters (especially the first time). For details of the boot
methods see separate documentation that is provided with the DaVinci HD EVM: TMS320DM6467
DVEVM Getting Started Guide (SPRUF88).
NOTE: See the mcvip_tvp5158\README.TXT file for instructions on running or building target
image and application. This is found in the zip file containing the DaVinci HD video/audio
driver source code.
