it means your link is not run well, you can check:
1. UB964's pattern gen. works correctly?
2. UB964's lock pin status?
3. UB964 and UB913a's mode_sel setting is correct or not?

regards,
Steven

(1) The pattern gen test mode is ok, can output colorbar;
(2) 0x4d = 0x3 // "Receiver PASS" and "FPD-Link III receiver is locked to incoming data" bit is 1, it should be locked
(3) Mode Sel:
1) 964:
0x4C 0x01
0x6D 0x7E // raw12
0x4C 0x01
0x71 0x1E // data type is YUV
2) 913：
0x05 0x18 or 0x3A

my 964 setting:
0x01 0x02
0x01 0x00

0x4C 0x01
0x58 0x58
0x5C 0xB2
0x5D 0x48
0x65 0x22

0x1f 0x02
0x32 0x01
0x33 0x01
0x20 0xE0

0x70 0x1E
0x4C 0x01
0x71 0x1E
0x4C 0x01

STATE REGISTER:
0x35 = 0x1 // tx pass bit is 1

0x4d = 0x3 // Receiver PASS and FPD-Link III receiver is locked to incoming data are 1
0x4e = 0x4

Hi,
Yes, the link is indicated as "lock" status.
you can further analyze:
1. what is the video format from camera? HS/VS is aligned with UB964's setting? video format YUV422-8-8 or YUV 12bits?
2. you can refer to page22 of UB964 EVM user guide, which has one reg. setting refer based on one specific case.

regards,
Steven
