Table 15. Troubleshooting with DM6467 DaVinci HD EVM

Symptom	Cause	Solution
No serial communication	Wrong serial port	Set terminal program to 115200 baud, 8 bit data, no parity, 1 stop bit. Check
	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.
Boot up process fails	No wired network	Connect Ethernet LAN cable to DaVinci HD EVM
	connection
	No FTP server available	Boot up arguments must specify the IP address of the computer that contains
		the image file to be loaded. An FTP server program must be runnning on that
		computer.
	No Linux host available	A PC running the Linux O/S or a PC running the Windows O/S with a virtual
		Linux O/S must be accessible on the LAN and provide a shared file system
		for the boot process.

Table 16. Troubleshooting I2C Connections and Cascaded EVMs

Symptom	Cause	Solution
When PC USB (VCC application) is I2C master for TVP5158
USB: I2C Error Code 1	I2C bus master	Check that jumpers W3 and W4 are connected across pins 1-2 to select USB
error message.	jumpered incorrectly.	as I2C master.
When DSP video/audio driver is I2C master for TVP5158
I2C error messages	I2C bus master	Check that jumpers W3 and W4 are connected across pins 2-3 to select
from demo application.	jumpered incorrectly.	DaVinci HD EVM as I2C master.
When cascading two TVP5158EVMs together
I2C error messages	I2C bus master	The Stage 2 TVP5158EVM feeds cascaded video and audio data through
from demo application.	jumpered incorrectly.
		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.
