Well, As you know, we now need a PLB version, XPS_LL_TEMAC is con= nected to PLB not MPMC2...yes I remember those days of Xilinx GSRD and MPMC= 2 however it seems that the current architecture has slight changes.
about the git repository of Xilinx, Although I do not believe on it, I'll= give it a try...thanks for info.

well, what about Grant Likely... a= nd his git tree?

Subject:=20 RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC

thanks for you reply david,

As far as I know the Linux dr= iver=20 for Xilinx PLB TEMAC was two parts : 1- adapter.c and 2- the rest of the dr= iver=20 files

Only adapter.c was really a linux related file and the rest of= the=20 files were Xilinx generic driver code for PLB TEMAC.

correct?
then=20 now, I know EDK 9.2 generates the needed Linux support package and needed=20 related files, so if this is the case can we use these files as the needed= =20 driver in our linux kernel?

by the way, i did never hear about this = git=20 repository before...can you describe us, where is it and how we can access = it=20 and which projects are now hosted by it?


thanks
