uCLinux is up and running! After hours of sysnthesis, compiling, and numerous error messages, I FINALLY have uCLinux running on my board

As explained below the hardware fully works, I am currently in the process of building the microblaze core capable of runing uCLinux. I have a linux machine which has been setup to compile using microblaze gcc, and this completes compilation of the uCLinux-dist.
Current status:
The PCBs have been made (4) and all components soldered.
The board works! Using Xilinx XPS I made a microblaze project using with generic SDRAM and using RS232 as standard IO. A small software app is automatically made which tests the memory and outputs the results on the consol. The board passed all memory tests, confirming the board works, as do all the conponents.
Description
So far I have only mainly been using quite simply Microcontrollers in
my projects. I decided to expand my skills and make something that will
be quite challenging.
This project is the design and build of a small FPGA board(s) (70mm X 65mm)
which I can use for future projects. The board will contain everything
needed to program and run the FPGA + it will include extra memory (SDRAM
+ EEPROM) and plenty of I/O. Due to the flexibility of the FPGA the boards
can be used for many projects.
The schematic entry and PCB layout was done in Eagle. Eagle seems to be quite popular, but takes a bit of time to get used to. PCB-POOL also accept the .brd files made by Eagle which made life easier.
The boards were made by PCB-POOL.
The service they provided was excelent and the boards are very high quailty,
it cost about £65 for the 4 boards.
