[microblaze-uclinux] Microblaze + uCLinux+ SATA+ PCI

["Sheikh M.Farhan" <sheikh.m.farhan@xxxxxxxxx>]

Hi all,

This is my second attempt to get some help from this mailing list. My problem is a bit complex and having no previous exposure to microblaze and uCLinux, it makes my problem even worst.

I am working on an embedded storage system with real time data acquisition with storage on SATA HDD. The embedded system houses a Spartan 3 xc3s1000 FPGA, SATA controller (Silicon Image Sil3512), microcontroller, SATA HDD and A/D. I am supposed to store real time data at 40 MBytes/sec on the SATA HDD and later on retrieve the stored data. For that I have to have a File Management Sytem on board. Actually it is this need of FAT that has made me explore microblaze and uCLinux. I am exploring the possibility of putting microblaze on my FPGA, porting uCLinux on it and using FAT support of it to access SATA HDD.

The problems I am facing and need guidance on are:

 

*The SATA controller that I am using talks through PCI interface. That means, I have to implement PCI interface on the FPGA side as well. This will be accomplished by using PCI bridge available at open-cores.org.

*The second problem is, I need to have the Linux driver for the controller, hopefully this will be arranged from Silicon Image.

*The third problem is, how to get all these things integrated? Is it possible what I am saying?

 

Kindly provide me some guidelines, I have seen many reference designs on microblaze but no one is actually talking about my problem area.

 

Thanks,

Sheikh Muhammad Farhan
