DS90UB936-Q1: Init sequence to receive pattern generation

Hi Zoe,
Yes, we are using cameras with 933 and want to use 953 to simulate those cameras using the pattern generation.

Sorry I didn't make myself clear.

The init sequence shown above is for the deserializer that receives the data (ds90ub936).

I think I can generate the pattern, but it looks like the deserializer is not set to receive the data.

What I am asking is any help to perform a init sequence for the deserializer to receive the data from the evm.

Best Regards,

Leonardo

Hello Leonardo,

Thank you for the clarification! If the only concern currently is to configure the deserializer to receive the pattern generation, the following two register writes from the code in my previous response would be needed. 

board.WriteI2C(desAddr,0x33,0x03) # Enable CSI-2, continuous clock mode
board.WriteI2C(desAddr,0x20,0x20) # Forward RX0 to CSI-2 output

The register setting for 0x20 corresponds to the RX port the pattern generation is being sent on. In this example, RX0 is the port for the 953. The initialization sequence previously shared for the 936. 

Reviewing the initialization script provided for the DS90UB936, I have the following questions: 

WriteI2C(0x4c, 0xf) 

I do not suggest writing this value to F as bits 3:2 of this register are reserved. Recommend 0x2 or 0x1 to enable writes to Port 1 or Port 0, or 0x3 for both ports. 

WriteI2C(0x5b, 0xb0) 

WriteI2C(0x5d, 0x48) 

WriteI2C(0x4c, 0x1) 

WriteI2C(0x5b, 0xb0) 

WriteI2C(0x5c, 0xb0)

WriteI2C(0x5d, 0x48)  

Why is 0x5c and 0x5d written to again here? 

WriteI2C(0x65, 0x48) 

WriteI2C(0x7c, 0x81) 

This line here is configuring the device for Raw 10 8-bit mode

WriteI2C(0x72, 0x0) 

WriteI2C(0x70, 0x1e) 

Raw 10 DT has default 0x2B to match the CSI specification. Why is 0x1E being written to here? 

WriteI2C(0x6d, 0x7f)

Raw 10 mode, coax overwriting straps

WriteI2C(0xc, 0x3) 

Since the device is in Raw10 mode, please verify Pattern Generator is sending Raw10 data as well. Specifics on what is needed for configuring Raw10 are listed in Section 7.6 Pattern Generation of the DS90UB953 datasheet. 

Best,

Zoe 

Hi Zoe,

in regards to the initialization script provided for the DS90UB936, would this be a better initialization:

i was checking the the capter "7.6.4 Code Example for Pattern Generator" from DS90UB953 datasheet which provides this example:

#Patgen RGB888 1920x1080p30 Fixed 8 Colorbar
WriteI2C(0xB0,0x00) # Indirect Pattern Gen Registers
WriteI2C(0xB1,0x01) # PGEN_CTL

WriteI2C(0xB2,0x21)
WriteI2C(0xB1,0x0F) # PGEN_VFP
WriteI2C(0xB2,0x0A)


My question at the moment is related with the PGEN_CSI_DI register. By default it has the value 0x24, which is RGB888. How do we get to this value? What would be the value for RAW10 mode for example? How do we know this?

Which changes should we make to be "compatible" with the initialization script above?

Best regards,

João

Hello,

i was using the ALP in demo mode to try to configure the pattern generation registers, but i'm missing the tab for pattern generation.




I did this commands after the sytem boots up.

Hello Zoe,

i seem to be missing something on the configuration.


I booted the system and read registers GENERAL_STATUS from the Serializer and DEVICE_STS, RX_PORT_STS1 and RX_PORT_STS2 from the Deserializer.

Hi João,

The CABLE_FAULT bit in RX_PORT_STS2 reflects an issue in the hardware set up. There is no lock between the devices as denoted by a value of 0x00 in register 0x4D. Have you tried changing the cable between the serializer and the deserializer? Are you using EVMs for this testing or a custom board? What modes are the SerDes in?

Best,

Zoe

Hello Zoe,

i do not think it's a cable problem (already tried a different cable) because when i boot the system the register RX_PORT_STS1 has the value 0x51 (you can see that in my previous reply), which means it has a LOCK_STS=1, LOCK_STS_CHG=1 and RX_PORT_NUM=1. It's only after i initialize the Deserializer that the value of the register goes to 0x00.

The deserializer is in a custom board, but the serializer is in a EVM.

SerDes modes? How can i know this? Which possible modes exist?

Thank you,

João

Hi João,

Since the NO_FPD3_CLK bit is set (0x4E = 0x02), then this indicates that there may be an issue with the cable connection, since no FPD-Link clock is detected at the deserializer's Rx input port. I believe this may be due to reading from the wrong port. When the register 0x4D is first read, it is reading for port 1 (0x51). There is lock but, port pass is low. When the deserializer commands are sent, reading from port 0 is enabled. Are you reading from the intended port? 

The first script shared is primarily being used to set up different I2C addresses. After the script is run, this is when lock is lost. This portion of the script is not necessary for PatGen itself as I2C addresses are strapped to the device. When reviewing the PatGen configuration, the serializer is addressed as 0x18, which is the strapped value. 

Additionally, please verify I2C pass through is enabled in register 0x58 to write to the serializer. 

Joao Martins said:

SerDes modes? How can i know this? Which possible modes exist?

Modes are strapped values referring to the clocking mode of the serializer and deserializer. This information is provided in Section 7.4 Device Functional Modes of the DS90UB960 and DS90UB953 datasheet. For example, a table of clocking modes and straps for the 953 is available below: 

Hi Zoe,

since the first script seems to be doing "nothing" i did not run it this time.

I'm going to use both ports, that's why i was trying to setup them simultaneously.

This time i booted the unit and read some registers. You can see them below:

Checking the CSI_RX_STS i can see the i have LENGTH_ERR and CKSUM_ERR errors, which i'm assuming is a problem with the pattern generation.

When checking the CSI_PLL_CTL it's possible to see that it's 800 Mbps serial rate.

When checking the BCC_CONFIG it's possible to see that it's 50 Mbps (default for CSI Synchronous back channel compatibility) and pass through is enabled.

If everything is configured correctly, will the LOCK bit in DEVICE_STS be set to 1?

Thank you,

João

Hi João, 

I reviewed the script to verify the PatGen parameters are correct for 1280x720 @ 30fps. In addition, I ran the script provided to get the following result using the Analog LaunchPad GUI: 

First, at initial start-up, would you be able to enable PatGen on the 953, without reconfiguring any other PatGen registers, and see if these errors occur? 

WriteI2C(0xB0,0x00) # Indirect Pattern Gen Registers
WriteI2C(0xB1,0x01) # PGEN_CTL
WriteI2C(0xB2,0x01)

The devices have the ability to lock without any software writes, given the hardware is set up correctly. The device should not lose lock due to software configuring PatGen. 

Best,

Zoe

Hello Zoe,

this is what i see when i have the DS90UB953-Q1EVM connected. The deserializer that appears on the ALP is a DS90UB954/958 but what i have is a DS90UB936-Q1.

I compared the files and the differences are the registers 0x4D, 0x50, 0x73, 0x74, 0x75 and 0x76.



If everything is configured correctly, will the LOCK bit in DEVICE_STS be set to 1?

Thank you,

João

Hello João,

Thank you for the comparison! The LOCK bit in DEVICE_STS is set to 1 when the device's hardware is set up correctly. In this case, the DS90UB936 and the DS90UB953 will be able to lock to one another once both devices are powered up. This is reflected in the first register dump where 0x4D=0x41. Port pass is not set at this time as the port pass criteria has not yet been met. When PatGen is enabled, the port pass criteria has been met and 0x4D=0x43. 

Registers 0x73-0x76 are different in the second register dump as they are based on the video data received by the DS90UB936. 

Register 0x50 changed due to a difference in the detected frequency however, this change is 1/256 MHz which does not impact the device operation. 

I see here that there are also no errors reported. 

From my understanding then, the DS90UB936 and DS90UB953 are being used. The customized script would be as follows: 

board.WriteI2C(Des Addr,0x4C,0x11)
board.WriteI2C(0x18,0xB0,0x02) # Indirect Pattern Gen Registers
board.WriteI2C(0x18,0xB1,0x01) # PGEN_CTL
board.WriteI2C(0x18,0xB2,0x01)
board.WriteI2C(0x18,0xB2,0x35)
board.WriteI2C(0x18,0xB2,0x2B) # RAW10
board.WriteI2C(0x18,0xB2,0x06)
board.WriteI2C(0x18,0xB2,0x40)
# PGEN_BAR_SIZE1
board.WriteI2C(0x18,0xB2,0x00)
board.WriteI2C(0x18,0xB2,0xC8)
# PGEN_ACT_LPF1
board.WriteI2C(0x18,0xB2,0x02)
# PGEN_ACT_LPF0
board.WriteI2C(0x18,0xB2,0xD0)
# PGEN_TOT_LPF1
board.WriteI2C(0x18,0xB2,0x02)
# PGEN_TOT_LPF0
board.WriteI2C(0x18,0xB2,0xD2)
# PGEN_LINE_PD1
board.WriteI2C(0x18,0xB2,0x12)
# PGEN_LINE_PD0
board.WriteI2C(0x18,0xB2,0x09)
# PGEN_VBP
board.WriteI2C(0x18,0xB2,0x00)
# PGEN_VFP
board.WriteI2C(0x18,0xB2,0x00)

Round robin forwarding of both ports from the deserializer should be enabled by default. 

Best,

Zoe 

Hello Zoe,

i executed the script and i have here the before and after of the deserializer registers (highlighted the differences).

It seems i'm getting errors like LINE_LEN_UNSTABLE and CSI_ERROR.

The filed LOCK in register DEVICE_STS (Address 0x04) is always 0. Shouldn't it be 1? Do we need to change the value of the filed LOCK_SEL at RX_PORT_CTL (Address 0x0C)?


In the script that you sent you start with this

board.WriteI2C(0x60,0x4C,0x11)

We are using port 1. Should it not be 0x12 instead of 0x11?




In a previous anwser you showed this panel. Where do i access this? I can't find it in ALP.



Thank you,

João

Hi João,

Going through the register dumps:

Joao Martins said:

Reg = 0,0x004D,0x43

The register values here are as expected as port pass and lock status are both set to 1 reading from port 0.

Joao Martins said:

Reg = 0,0x004C,0x51

Register 0x4C is used to select which port the device is reading and writing to for the port specific registers. In this case, it is set to write to port 0 and read from port 1. 

Joao Martins said:

Reg = 0,0x004E,0xCD

The register values here as already pointed out are line length change, line length unstable, line count change, and CSI error. Have you tried to read this error once and then immediately re-read? Are these errors reoccurring?

These errors may occur at the start of PatGen due to reconfiguring the video parameters. 

Joao Martins said:

Reg = 0,0x007A,0x0C
Reg = 0,0x007B,0x01

The CSI errors are length error and checksum error with a CSI error count reported of 1.

The lock bit field in register DEVICE_STS denotes which condition is met for the LOCK status pin to be set to 0 or 1. In this case, the LOCK pin will go high when port 0 is locked.

Yes, apologies for the misunderstanding here. When using port 1, 0x4C should be set to 0x12. I have edited the code sent with this I2C write to reflect this. 

Joao Martins said:

The panel appears in Analog LaunchPAD when connected to the deserializer on the Information tab. 

Since the PatGen test where it was only enabled and no other settings were reconfigured was using port 0, the problems using port 1 can still be due to hardware set up. I went through the script again using a DS90UB954 and DS90UB953 with port 1 locked and sending PatGen from the 953 and verified no CSI errors occur with this script. 

Please see the following corrected script for Port 1: 

devAddr = 0x60 #check deserializer address 
serAlias2 = 0x1A #port1

board.WriteI2C(devAddr, 0x4C, 0x12)  #read/write port0 and port 1 registers

board.WriteI2C(devAddr, 0x32, 0x03) # Write to the CSI TX Port 0 and Port 1 registers, Read from TX Port 0
#second serializer enable patgen
board.WriteI2C(serAlias2, 0xB0, 0x02) #IA_AUTO_INC=1
board.WriteI2C(serAlias2, 0xB1, 0x01)
board.WriteI2C(serAlias2, 0xB2, 0x01)      
print "patgen port 1 is enabled"

Hi João,

Were you able to get PatGen working successfully? Please let me know if any further assistance is desired.

Best,

Zoe

Hi Zoe,

i'm very sorry for the late response. I went on vacation and forgot to give an update.

We were able to get PatGen working sucessfully.

Thank you for all the help you provided.
