settings that COM port is available in the Windows Device Manager and is not being
used by another program.
Wrong cable type Use a null MODEM 9-pin serial cable. Pins 2 and 3 at one end should be
wired to pins 3 and 2 at the other end.

connector J2 to connector J3 of the Stage 1 TVP5158EVM.
On the Stage 2 board, check that jumpers W2, W1, and W0 are connected
across pins 1-2, 1-2 and 2-3 (L, L, H) respectively, to specify slave address
0xB2.
On the Stage 2 board, check that jumpers W3 and W4 are both removed to
allow I2C to be mastered by the stage 1 board.
Also on the Stage 2 board, remove W7 and W8 to remove the second Audio
DAC from the I2C bus.
The Stage 1 TVP5158EVM can have I2C controlled by USB or the DaVinci
HD EVM.
Any changes to the above setup require that VCC be exited and restarted so
that the correct I2C slave address(es) can be selected.
