DS90UB960-Q1: 960 registers sample code.

Hi,

Where are issues in your setup coming from?  If you have set your strap values correctly and are able to communicate with the 953s you should be able to forward the video data accordingly in the FRD_CTRL registers.

Hi,
     At present, only the input source (sensor + 953) is known, and the data input to 960 is uyvy 1920 * 1080 30fps. We need to initialize the register of 960.
However, since we debugged 960 for the first time, we don't know which basic registers need to be initialized to get image data?

Hi,

It should be relatively simple, if you can verify that the serializers can communicate with the 960 you should just need to enable CSI forwarding in 0x20 and then configure the CSI port in register 0x33.

So set register 0x32 to select which CSI port to turn on then enable it in register 0x33.  Also set register 0x20 to enable forwarding of all 4 ports.

Nick

Hi,

At first, thinks you for your timely reply.

1. Now I can read the following registers of 960 through I2C:
0x5b = 0x24: indicates that a connection has been established with the serializer, and reads that the ID of 953 is 0x24
0x4d = 0x83: indicates that bit [0] = 1, receiver is locked to incoming data
0x73,0x74 = 0x438 = 1080: indicates that 1080 rows of data are received in a frame
0x75,0x76 = 0xf00 = 3840 = 1920 * 2: indicates that 3840 bytes are received in a row.
Because the transmission format is uyvy (yuv_8bit), one pixel occupies 2 bytes, so there are 1920 pixels in a row
The RX of 960 can be determined according to the value of the above registers.The RX_2 of 960 has received 1920 * 1080 YUV data.
I wonder if there is a corresponding register that can read the frame rate?
log:
# ccidbgr /dev/cci1 0x30 write 0x4c 0x24
0x4c <- 0x24
# ccidbgr /dev/cci1 0x30 read 0x4c
0x4c -> 0x24
# ccidbgr /dev/cci1 0x30 read 0x5b // Remote Serializer ID
0x5b -> 0x32
# ccidbgr /dev/cci1 0x30 read 0xdb
0xdb -> 0x68
# ccidbgr /dev/cci1 0x30 read 0x4d // Receiver is locked to incoming data
0x4d -> 0x83
# ccidbgr /dev/cci1 0x30 read 0xd9
0xd9 -> 0x00
# ccidbgr /dev/cci1 0x30 read 0x73
0x73 -> 0x04
# ccidbgr /dev/cci1 0x30 read 0x74 // LINE_COUNT = 0x438 = 1080
0x74 -> 0x38
# ccidbgr /dev/cci1 0x30 read 0x75
0x75 -> 0x0f
# ccidbgr /dev/cci1 0x30 read 0x76 // LINE_LEN = 0xf00 = 3840 = 1920*2 for UYVY
0x76 -> 0x00
#

2. How to determine that 960 has sent data to Mipi TX port?
I try to read the value of the following register.
According to the read 0x35 = 0x1, can it indicate that 960 has indeed sent the data?
# ccidbgr /dev/cci1 0x30 read 0x33 5
0x33 -> 0x03
0x34 -> 0x00
0x35 -> 0x01 // [0] : TX Port Pass
0x36 -> 0x00
0x37 -> 0x00

3.According to your reply above, I have set the following registers.But I can't get the image yet.

What else need to be checked for 960?

# ccidbgr /dev/cci1 0x30 read 0x33
0x33 -> 0x03
# ccidbgr /dev/cci1 0x30 read 0x20
0x20 -> 0x00
#

Thinks.

Hi,

I can now certain from CSI TX_Port0 output, and set 0x20 = 0x00, which is indeed forwarded from CSI Prt0.

I want to know how to confirm that the CSI TX port of 960 has sent the data? Can I read some registers?

Hello,

I don't think there is a register that states the data has been transmitted but you can look at 0x4E[4] to see if there is a buffer error with the assumption that if the buffer isn't overflowing then it must be being emptied.

Nick
