Hello.
I have TDA2PX and two ub960 connected to it via CSI2 interface: first UB960 use 4 lanes of CSI2 ans second UB960 use only 2 lanes. On TDA2PX I see 30 fps flow from first UB960 and no frames from second UB960.
Then I turn off pattern generator - I see video streams from FPDLink cameras connected to both of UB960. Only pattern generator on second UB960 (which has 2 lanes setup) is not working.
My setup:
- Vision SDK 3.0.7
- late attach
- pipeline on M4 core (ipu2)
UB960 initialization:
