I have ML605 board with MicroBlaze and PetaLinux OS running, I will be using Xilinx soft IP core " PLB2PCIe bridge"
I need to connected to a SCSI device (SSD) using PCIe protocol, PetaLinux does provide device drivers for SCSI, it uses Kernel: Linux/Microblaze 18.104.22.168 which is a minimized version of the original Linux/x686 22.214.171.124.
However, in the (make menuconfig) in 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 126.96.36.199 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?
