Hi all, I use a Xilinx Virtex-4FX (with powerpc) Board (Ml403) with U-boot and Linux.
I am currently wondering if someone has experience with the emaclite driver. When I unset the "ping pong" (double buffering) parameters of the core, I can use it unter Linux and U-boot. But the performance is near to non-functional (wget tells me about 10kByte/sec). Then I switched to double buffering. Now it runs very well - but only under Linux. I found a driver (xilinx_emaclite.c) in the U-boot git. That completely refuses to work correctly (of course with parameters corrected). The other driver I once found "somewhere" (in the Petalinux distribution). It at least worked without the double buffering. Both drivers talk about the ping pong options in their source, so I think they *should* know about it. Does anyone know that problem? Is there an improved driver around?
