Other Parts Discussed in Thread: ALP
We have setup 2 x 1080 30ips streams yuv 422 8bit from 2 separate 953 devices with the same Frame sync from one 953 feeding both sensor frame syncs via GPIO2 .
We can see a 10% duty 30 FPS sync on the scope and ALP reports 1920 x 2160 received per RX port.
The code below sets up the link after the sensors are running

# frame sync is GPIO2 xx1x
# 953A is common to both image sensor sync pins

board.WriteI2C(UB953A_alias,0x0e,0xf0) # sets all GPIO as outputs on 953A :
board.WriteI2C(UB953A_alias,0x0D,0xF0) # Enable Remote of all 4 GPIOs from DES
board.WriteI2C(UB954,0x6f,0x8A) # BC GPIO Control: Link BC GPIO2 to be Frame Sync output
board.WriteI2C(UB954,0x18,0x01) # FS CTL: Enable Frame Sync and set Internal Frame Sync for Port0 also feeds port1 953B

We are not seeing any video at the csi2 receiver end so need to examine the 954 output , does the above script seem OK ?
If so , is there a set of registers we can probe to examine the output of the 954
