RTOS/TDA3XEVM: Serializer alias address

Blessy Abraham

Part Number: TDA3XEVM

Tool/software: TI-RTOS

Hi,

i have four Serializers along with sensors connected to the EVM board through ub964 Deserializer. While probing the I2C connections, i am getting error as shown below. Serializer alias address 0x7A only gets probed successfully. The rest three (0x74, 0x76, 0x78) gets failed. Even though this happens, the sensor aliases are detected and the 4 camera output is obtained.

Hi Blessy,

Can you please share the UB964 configuration's?

Hi Sujith

Thank you for your reply. I got it solved. The serializer physical address mentioned was wrong.

I have another doubt in one of the code in bsputils_ub960.c,

BspUtils_Ub960I2cParams gUb960Cfg_IMI[] = {
{0x01, 0x01, 0xFFF}, /* Digital Reset 0 */
{0x1F, 0x05, 0x4FF},

/* IMI OV10640 1 */
{0x4C, 0x01, 0x0},//RX0
{0x58, 0x58, 0x0},//BC FREQ SELECT: 2.5 Mbps
{0x6D, 0x7D, 0x0},
{0x5D, 0xBA, 0x0},--------------------------------------------------------------> Serializer physical address provided here.
{0x65, ((UInt8) (IMI_PORT_0_SER_ADDR << 1U)), 0x0},
{0x5E, 0x62,0},------------------------------------------------------------------------> Sensor address is 0x62?
{0x66, ((UInt8) (IMI_PORT_0_SENSOR_ADDR << 1U)), 0x0},

When i had referred the datasheet of OV10640, the physical address was mentioned as 0x60. Why 0x62? How have you designed it?
while referring datasheet i saw that the 0x300C register sets the address, but couldn't find that setting. So how have you come up with 0x62?
PS: I am getting the camera output using 0x62 register value. Tried changing it to 0x60, not getting the output.

Could you please help me through.

Hi Blessy,

It is nice to hear that you solved the issue. I will close this thread.
The discussion of the OV10640 address can continue in the other thread:

In Ov10640, lower 3 bits of the address comes from the GPIO.

But according to the tidrjx7 schematic (OV10640 interface with ub913) Gpio0 used for fclk, GPIO1 - GND, GPIO2 - GND, GPIO3 - GND. So how 0x62?

Hi Blessy,

The IMI module is not same as "tidrjx7". In case of tidrjx7, what you have done/saying is correct. The sensor address should be 0x60.

"gUb960Cfg_IMI" supports IMI module.
