Tool/software: Linux
Hello,
I am trying to interface a DS90UB964 FPDlink-IIIb hub with a DRA76P processor (4 lanes). I currently reworked the CAL driver in order to support four capture context, but I am unable to perform an acquisition.
When I enable the pattern generator on the DS90UB964 hub, I can see the clock coming out from the hub to the processor. If I then start an acquisition through v4l2, the ComplexIO block completes its reset, but the RESETDONERXBYTECLK never goes to 1. If I enable ComplexIO IRQs, I can see several ERRSOTHS and ERRSOTSYNCHS errors.
Please note that the same driver, when used with a stream coming from a DS90UB960 deserializer, allows to perform an acquisition.
Do you have any hint to solve this issue? Have you ever connected a DS90UB964 hub to a DRA76P processor?
Best regards,
Francesco
