It seems that the Renesas µPD720200 host controller has some problems with ISO transfers. We have seen burst transfers where some packets have zero length but do actually contain valid data.
Do you have any explanation for this?
Renesas µPD720200 firmware version: 188.8.131.52
FX3 SDK: 1.2.1
It might be possible that the burst size you are using might not be supported completely by the Renesas controller.
