That's right. AFAIK, The 2.6 kernel is not yet supported by the Xilinx EDK tools; and so it cannot generate a 2.6 BSP. If you want to use the generated BSP; use the montavista 2.4 kernel. > And also, I saw this thread: "Migrate Xilinx Vertex support from the OCP > bus to the platfom bus" > > http://patchwork.ozlabs.org/linuxppc/patch?id=3933 > Does it mean all of onchip peripherals for Virtex-4 FX must reside on the > PLB bus instead of OPB (OCB) bus ? No. Platform bus is a Linux construct to make it simpler to handle "directly attached" devices. ie. Anything that the processor can access directly w/o PCI et all. OPB and PLB devices are both 'platform' devices in Linux 2.6 terminology. > (i.e. during the process of creating the ref design for Linux using Xilinx > Platform studio, I have to select PLB peripherals instead of OPB > peripherals. Is is correct ?) No, use whatever peripherals you want (either PLB, or OPB). Just be prepared to port device drivers for anything beyond a serial port. > > BTW, do you have a sample ref design for ML-403 board for Xilinx Platform > studio ? Why not use the ref design that Xilinx provides? (I have a number of designs that work; but most of the time I use the ML403 ref design because I know it's proven) Cheers, g. -- Grant Likely, B.Sc.
