I'm designing with Virtex 5 XC5VLX50T ML505 and DDR
I'm using EDK 10.1 and the code that i wrote in it is too large to fit the FPGA
text data bss dec hex
110440 1484 4640992 4752916 488614
The DDR has a starting address 0x90000000.
What i want to do is to use PROM so that the FPGA is configured at power-on, also because of the size of the .elf file i want the same PROM to load the .elf file into the DDR at power-on.
Is there any post or tutorial available to use?

I'm loading the .BIT file into the FPGA without 'Mark to initialize the BRAMs'.
What i do then is to use 'Launch XMD' to download the .ELF and start my application.
This isn't what i wanted to do every time the power of the board is cut off.

When I execute this command I have a leak of memory.
/home/mavouzi/Xilinx/14.4/ISE_DS/ISE/bin/lin64/data2mem -bm system.bmm -bt system.bit -bd boot_esssai.elf output.bit
I place an examle of error that I can see in the console this is the latest. Do you have an idea why I have a leak of memory.
INTERNAL_ERROR:Data2MEM:45 - Memory allocation leak of 8 bytes at 0x019B15F8 for 'CharPtrArrayType' data.
Total memory in use at allocation was 7605 bytes.
Source file "StringUtils.c", line number 901.

I have spartan 6 and I want programme the flash with a file who contains the .elf and the .bit. I think that with the impact 14.4 I load the file output.bit in the cable SPI. Unfortunately the file output.bit did'nt generate.
