TVP5158EVM Evaluation Procedures
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.
