PCI Express Bus Driver for PetaLinux - Xilinx ML605 FPGA
Dear All,
I have Xilinx ML605 FPGA development board with MicroBlaze and PetaLinux OS running, I will be using Xilinx soft IP core " PLB2PCIe bridge" configured as root complex I want to connect it to a SCSI device (SSD) using PCIe protocol, PetaLinux does provide device drivers for SCSI, it uses Kernel: Linux/Microblaze 2.6.37.6 which is a minimized version of the original Linux/x686 2.6.37.6. However, in the (make menuconfig),the Bus options, it only provides "PCI support", which includes: "Xilinx PCI host bridge support" "PCI stub driver" "PCI IOV support" there is no support for PCI express as in the original 2.6.37.6 kernel. what are my options here? can I take the standard linux PCIe drivers and make them work for Xilinix' PLB2PCIe bridge? Should I write a module for PCIe from scratch ? Please, if any one can help. I need some guidance here because I'm totally lost. How do I make PetaLinux support Xilinx PLB2PCIe bridge IP core? Best Regards, bfr03 |
