CCS/TDA2SX: Initialisation Sequence for Deserializers

Hi,

Can anyone help me on this,

i am waiting for response

Hi Arunkumar,

Is the IMX390 camera from D3? 

This is because this camera board is already supported in the vision sdk, you could get the configuration for 953/960 from vision sdk.

Hi Brijesh,

Thanks for quick response,

Actually, It's not for D3. It's for our Custom Board. The connection is like this.

Even I referred D3 configuration also. But I am asking I2C sequence and all other initialization for our custom board.

Whatever i mentioned the sequence registers above are right ? Do I miss any information?

Hi ArunKumar,

D3 camera is what we support, for the new camera, it requires bringup.. Checking the sequence will not help much.

Can you just try and see if it works.

Hi Brijesh,

I tried like D3 Intialisation for my Camera. But in my custom board, we are not using IO Expander. I directly used GPIO to control all pins.

These are the steps i did :

1) Set PDB bits high for all FPD Link channels

2) Set Lock and Pass bits high for Driver cam FPD Link channels

3) Set OE bits high for all FPD Link channels

But I missed other 2 steps :

1) How to Enable VDD_FPD Sepic A, B - EN ? ( We are not using Sepic) ?

2) How to Enable VDD_FPD Sepic Enable output power FPDA & B SW EN  ?

which pins i have to enable ??

Hi Arunkumar,

Please check schematic of the board and set the pins accordingly.

Hi Brijesh,

As per the schematic, i set the pins as like D3. These are the below pins configured in my custom board,

• FPD_PDB
• FPD_LOCK
• FPD_PASS
• FPD_OEn

Anyhow in D3,  above pins and these below pins also enabled.

/*Select voltage and Sepic A, B - 12V Sel*/
   if (voltage == BOARD_FPD_VOLTAGE_12V)
    {
        Bsp_boardSetBitsInGPIOExpander(KTCA9539_U33_I2CBUS, KTCA9539_U33_I2CADDR,
                                       BOARD_TCA9539_OUTPUT0_REG, 0x11);
    }*/

    /* Enable VDD_FPD Sepic A, B - EN */
    /*Bsp_boardSetBitsInGPIOExpander(KTCA9539_U33_I2CBUS, KTCA9539_U33_I2CADDR,
                                   BOARD_TCA9539_OUTPUT0_REG, 0x22);*/

    /* Enable output power FPDA & B SW EN */
    /*Bsp_boardSetBitsInGPIOExpander(KTCA9539_U33_I2CBUS, KTCA9539_U33_I2CADDR,
                                   BOARD_TCA9539_OUTPUT0_REG, 0x44);*/

For my custom board,

i am not using sepic chip. The VDD and VCC pins not configured as GPIO. Its handled in HW.

So, My Question is :

1) In 934 & 954 Deserializer what are the pins have to do pin muxing ?

2) Is selecting FPD_Voltage from S/w side is neccessary ?

Hi all,

Can anyone help me on this,

i am waiting for response

1) What are the initialization sequence has to follow ?

PDB, LOCK, PASS, OE configure as output and set to high for both De-serializers.

2) I want to know the CMLOUT sequence for  934-933 and 954-953 De-serializer.

Am I did proper sequence as like above mentioned in the post ? Any changes needed ?
