Dear forum members,
We are facing LAN trouble now. We are using Vybrid VF5 chip and Timesys Linux(3.0) on our prototype.We think the trouble relates to Vybrid errata e6358. The symptom is as follows:
(Symptom)
(Condition)
We think this issue is related to the Vybrid errata e6358, “ENET: Write to Transmit Descriptor Active Register (ENET_TDAR) is ignored”. We made a patch to avoid that errata (the patch is attached to this message), then the trouble does not occur after the modification.
We are not so familiar with both linux driver and Vybrid so please give us the comment whether our patch is designed appropriately.
Best regards,
Makoto Katsukura
