5.2.3.1DaVinci HD EVM as TVP5158 I2C Master
Table 4 describes the jumper settings to set the DaVinci HD EVM as I2C master for the TVP5158. In this case, the Linux application and driver software control the entire system. Audio can be output from the TVP5158EVM or from the DaVinci HD EVM. See Section 5.2.1 and Section 5.2.2 for audio configurations.

5.2.3.2PC USB as TVP5158 I2C Master with DaVinci HD EVM
Table 5 describes the jumper settings to set the PC USB interface as I2C master for the TVP5158. In this case, the Video Control Center application software can be used to experiment with TVP5158 register settings through a graphical user interface.
NOTE: This system configuration has known I2C issues that sometimes occur when PC USB and DaVinci HD EVM I2C buses are used independently.

5.2.3.3Jumper Settings for Audio/Video Cascade Configuration
CAUTION
If two or more TVP5158EVM boards are cascaded together, care must be taken that the leads on the J2 and J3 connectors are in alignment, because the connectors are not keyed.
Table 6 describes the jumper settings for a second stage TVP5158EVM connected for video/audio cascade operation. In this case, the I2C slave address must be set be set differently than the first EVM. The I2C Master jumpers must be removed to allow the first stage EVM to control I2C (either from USB or from DaVinci HD EVM). USB should be connected to the first stage EVM if used. The Audio DAC I2C must be disconnected on the second stage, since they are both at the same I2C slave address.
