Part Number: DP83848YB
I am having a problem daisy chaining two DP83848YB parts in a JTAG chain. I had problems on my board with my 6 device JTAG chain. I jumpered around the DP83848YB parts and everything runs fine.
Using the Corelis chain integrity debug tools and two of the DP83848I-MAU-EK eval cards. I can run chain integrity on each eval card independently and it passes just fine. When I daisy chain the two eval cards TDO to TDI they fail just like the chain on my PWA. Why do the DP83848YB parts not work in a JTAG chain?

In reply to Alex Panos62:
Yes that is the same error I saw, and yes I agree the BSDL looks correct. We have already implemented a work around, thank you very much for following up and confirming my test results.
