DS90UB954-Q1: 954 and 953 register setting for non-sync mode

Thanks your comments.

Can you please let me known how to reconfigure each device locally?

E.g :

Which register need to change after power up?

Any recommend for those register sequence , which one need write first......

Thank

Yutai

You need to reconfigure the SER first and then apply digital reset (reg 0x01[0]). After that reconfigure the DES.

Hi Hamzeh

From my understanding as you mention above.

1. 954&954 working at sync mode from HW  Mode pin (resistors  setting) after power up.

2.  SOC through 954 back channel to reconfigure SER(953) .  Register 0x03 value change to 0x5A.

3. Then apply digital reset (reg 0x01[0]) for DES (954)

4. After that reconfigure the DES (954). Register 0x58 value change to 0x5A,

5.  Finally configure Image sensor.

Q1: Please help to check if the process is correct?

Q2: Please help to check if I missing anything?

Q3: It is best provide some I2C script demo for non-sync  if you have it.

Thanks

Q4: Why we need first to reconfigure SER(953) then to reconfigure DES(954) ? 

Q5: Can you please check if the below script is correct or not for reconfigure 953&954 to non-sync mode.

Hello Yutai,

Theoritically you steps should work, but I am not 100% sure if this is the case. In the previous post you were talking about "locally" setting the SER registers, but now you want to set them remotely!!

You need to reconfigure the SER first, otherwise if you reconfigure the DES first you will not be able to communicate with SER anymore.

I will check your code and comeback to you tomorrow!

Thank you.

Waiting your comments about our I2C code.

Please share more information about  non-sync mode reconfigure.

Yutai

Hi Hamzeh

Thanks for your comments. 

Do you means we must to re-configure SER(953) in step 1 and re-configure DES(954) in step2 after power on. Is it correct ?

BTW: can you please share your Email to me ? Because our software colleague will discuss with you more in detail. 

Step 1: 

###SER(953)###################
board.WriteI2C(0x12,0x01,0x02)### RESET
board.WriteI2C(0x12,0x03,0x5A)### NON-SYNC

etc

...................................................................

Step 2: 

###DES(954)###################
board.WriteI2C(0x60,0x01,0x02)### RESET
board.WriteI2C(0x60,0x10,0x13)### GPIO
board.WriteI2C(0x60,0x4C,0x01)### FP3 PORT SEL
board.WriteI2C(0x60,0x6D,0x7C)### PORT CONFIG
board.WriteI2C(0x60,0x58,0x5A)### NON-SYNC

etc

This is correct.

Thank you, Hamzeh

Have a nice weekend. 

Hi Hamzeh

Update information to you in below. 

Hi Hamzeh

Update status to you.

Our SW colleague follow up your init seq but we have failed to change to non-sync mode. 

So in order to solve this issue asap. We want to do the below action to fix this issue. 

Please help to review HW&SW action and give your comments. 

HW Action:

Mode pin: 954 remove pull up 78.7K resistor, keep pull down 97.6K resistor => HW default mode is csi2 non-sync mode.

SW Action:

Because camera design have fixed and it can not change HW design.But the serializer mode can overrides from register.

So we have to change 953 register 0x03 to 0x5A 

## 954 I2C ID 0x60

## Step 1 configure 954 register

0x60 W 0x01 0x02 Reset
0x60 W 0x10 0x13 GPIOx_PIN_CTL (outpue enable)
0x60 W 0x4C 0x01 FP3 PORT SEL (port 0 write enable)
0x60 W 0x6D 0x7C PORT_CONFIG( Coax mode ; CSI mode)
0x60 W 0x58 0x5A BCC CONFIG ( Sync-back channel mode)
0x60 W 0xBA 0x83 FP3 ENC CTL (fpd3 encode crc)
0x60 W 0x1F 0x00 CSI PLL CTL (1.6Gbps serial rate)

0x60 W 0x72 0x00 CSI VC MAP
0x60 W 0x5C 0x12 SER ALIAS ID (7 bit remote serializer 953 alias ID; bit0: auto ack)

## 953 I2C ID 0x12

## Step 2 configure 953 register

0x12 W 0x01 0x02 Reset
0x12 W 0x03 0x5A BCC CONFIG ( Sync-back channel mode)
0x12 W 0x41 0xA9 SLAVE ID ALIAS 0 (7 bit remote serializer alias ID; bit0: auto ack)
0x12 W 0x42 0x01 SLAVE ID ALIAS 1 (7 bit remote serializer alias ID; bit0: auto ack)

0x12 W 0x06 0x41 CLKOUT CTRL0 (HS_CLK_DIV=4, M=1)

0x12 W 0x0B 0x13 SCL HIGH TIME
0x12 W 0x0C 0x26 SCL LOW TIME

## Step 3 configure image sensor AR0220 register

Hello Yutai,

If you change the DES to Non-Synch, and your Camera is by default set to Synch mode, you will not be able to communicate with the camera anymore!

The only reliable way is to change the Camera HW, or to override the Camera Mode LOCALLY not Remotely!

Hi Hamzeh

I can successfully run the code as mention in both HW&SW action  Please find ALP tools run status.

So I don't understand your comments " you will not be able to communication with camera anymore"

Hello Yutai,

Yes, as I said, if your DES is by default set to Non-Synch mode, but the SER is set to Synch Mode, you will not be able to communicate between them!

I believe, your SER is always in Non-Synch Mode!

Hi Hamzeh

No, The SER default working in sync mode. 

Because I use ALP read the 0x03 register the value is 0x48. So I believe it can communicate after power up before I run the Python scripts.

Thanks

Yutai

Hi Hamzeh

Although I can use ALP tools to communicate with DES (non-sync mode) and SER(sync mode) after power up.

And I can set correct register to change SER run in non-sync mode used Python scripts ( e.g. board.WriteI2C(Alias953, 0x03, 0x5A)

But our SW team have issue to implement it and he get the error log to write register 0x03 address value to 0x5A. 

So it is my confuse about the ALP tools and SW BSP code. 

@ Hamzeh  // Can you please reproduce it in your side ?  

HW Setup:  954 EVM board / 953 EVM board / Coax cable / Power supplier / USB2ANY with ALP tools

Step 1:  954 EVM HW mode pin setting => non-sync mode

Step 2:  953 EVM HW mode pin setting => sync mode

Step 3: Power on 954 EVM, coax cable (poc) to power on 953 EVM

Step 4: USB2ANY with ALP tools to monitor 954&953 default register. 

Step 5: Please help check your result:

            954 default register 0x58 => 0x5A  ；953 default register 0x03 => 0x48     Is it correct ?

Step 6: Run  Python scripts to implement DES to non-sync mode.

            e.g. board.WriteI2C(Alias953, 0x03, 0x5A

Step 7: Please help check your result

            954 register 0x58 => 0x5A  ；953  register 0x03 => 0x5A     Is it correct ?

Thanks

Hello Yutai,

Sorry, I can't reproduce this in my home office. I do not have the right equipments to do that!

Hi Hamzeh

Understanding......  I will discuss with TI Local FAE team to reproduce this test case.

Thanks

Yutai

Okay! Thank you!
