Tool/software:
Hi Team,
We are are trying to access the FPD-IV UB971 serializer using the FPD-III UB960 de-serializer.
The setup is like below:
Board 1 : Custom board has J721s2-SOC connected to UB971 serializer via CSI-Tx.
Board 2 : J721s2-evm with Fusion1 board connected.
Both the boards are connected using serial Fakra cable.
The issue arises when we try to access the UB971 using the Fusion1 de-serialzier from the J721s2-EVM board. (Here the host is J721s2-EVM) . We are not able to detect the serializer, LOCK status bit of de-serializer is also '0'.
But when we use the Fusion2 board which has FPD-IV UB9702 de-serialzier, we are able to access the serializer, so hardware looks fine.
So, the query is :
1. Is FPD-III UB960 de-serializer compatible with FPD-IV UB971?
2. Does FPD-IV UB971 serializer has the capability to fallback to FPD-III mode?
Thanks,
Jayanth.
