DS90UB954-Q1: Setting SER_ALIAS_ID (Address 0x5C) + Enabling PG

Part Number: DS90UB954-Q1

Hello,

I am trying to bring up TI 954 with 913. We already brought up 913 with 914 so, 913 camera should be OK.

I can read write other registers but somehow 0x5C cannot be written. Anyone knows why ?

E.g. I can modify 0x0c below (I2C address for 954 is 0x38)

root@computing# echo 38 0c > i2c_reg_value ; cat i2c_reg_value
I2C read OK: id = 0x38, addr = 0xc, data = 0x83

root@computing# echo 38 0c 80 > i2c_reg_value ; cat i2c_reg_value
I2C read OK: id = 0x38, addr = 0xc, data = 0x80

However I cannot modify 0x5C

root@computing# echo 3a 5c > i2c_reg_value ; cat i2c_reg_value
I2C read OK: id = 0x3a, addr = 0x5c, data = 0x0

root@computing# echo 3a 5c aa > i2c_reg_value ; cat i2c_reg_value
I2C read OK: id = 0x3a, addr = 0x5c, data = 0x0

root@computing# echo 3a 5c > i2c_reg_value ; cat i2c_reg_value
I2C read OK: id = 0x3a, addr = 0x5c, data = 0x0

Once I verify this I2C back channel access, I want to enable pattern gen and see how my FPGA is getting the MIPI video stream.

If anyone has steps to try pattern generator, please share with me.

FYI, I dumped some register reading below.

Kwan,

Register 0x5C is reserved for the Serializer Alias ID value - Is your question that you have trouble writing the Alias ID value of the 913 to Register 0x5C?

When setting up your script,
Be sure to enable the correct port for read and write on the 954 (Register 0x4C)
Set up the Back Channel Config (Register 0x58)
Set up the Serializer ID (Register 0x5B)
Set up Serializer Alias ID (Register 0x5C)
Set up Slave camera ID (Register 0x5D)
Set up Slave camera Alias ID (Register 0x65)

Regards,
Jonny

Kwan,

In regards to setting up the PatGen for the 954, please refer to the comments in this E2E thread: e2e.ti.com/.../671813

There is some example code in the comments that shows how to set up the Pattern Generation.

Regards,
Jonny

Hi, Jonny

Thanks for your reply.

1) Pattern Generation now works.

I do receive below pattern. I guess this is expected pattern.

Still more questions on pattern generation.

1-a) I play with CSI_PLL_CTL and for both 1.6G and 800Mbps settings, I get same pattern from FPGA side. Does it make sense to you ?

1-b) FPGA side is configured as YUV 422. Does it have any meaning ? I guess test pattern just generate fixed pattern and FPGA receive it ? Then even for real case, for data receiving, FPGA color setting has no meaning ?

2) For back channel I2C access, it still doesn't work. (Eventually I want to make sure camera gets triggered but for now, I am focusing on back channel I2C work to make sure, the communication between 913 and 954 are good.) Below is register dump. Could you check it and let me know what is not right ? I did set the registered you mentioned.
