Hi,
thanks for the quick Answer,
The other cpsw's are also occupied for other uses.
I had a meeting with my customer yesterday and we hopefully found another
solution using a VLAN-Routing, so we only need the two CPSWs.
But because I've the AX88760 here, I try to give more information on this
bug next week to get it fixed although we don't need it any more.
Best Regards
Pascal Speck

I hope, Im thinking on all Information you need and I have the right
person.
I dont really know if the problem is sourced on musb or the ASIX driver.
The error is reproducible every time I start the system over NFS and I
have the possibility to debug into the kernel within KGDB, but at this
moment I dont know the structure of musb networking, so I dont know
where to start debugging.
Could you please give me a fast answer, if Im right on this way
telling you
if you want dedicated support you shouldn't be depending on a mailing list
giving you *free* advice.
the bug or if I should try something else and provide more information.
I really need this working driver for a very time-critical project of
one of my customers and Im willing to work on a fix if you tell me how.
what is your customer doing and why can't s/he use the internal ethernet
controller from AM335x ? There are two CPSW ports in that device.
I have the following Problem:
When booting the Linux Kernel with the following constellation:
AM335 -MUSB - AX88760 over NFS
