First of all -> check that your mss contains memory size because your board
doesn't have 64MB memory but only 32MB. But please keep 64MB in HW design ->
that's ok.

Why did you compile it? It is pre-build folder -> there is download.bit already
prepared and linux & u-boot too.

Thanks, I found them now.

your serial is uartlite not serial8250. serial8250 is for uart16550.

I hope you have working xmd on windows.
Go to hardware/reference-design/pre-build/Xilinx-Spartan3E500-RevD/implementation/
There is download.bit -> please load it to your board.
Then go to ../images.
run xmd
connect mb mdm
dow -data image-2.6.bin 0x24000000
rwr pc 0x24000000
con

and look to your serial line on x86 or whatever you use. Just for sure - serial
line baudrate should be 115200.

What does happen?

I do have xmd in windows. I started it up and try to connect using the connect command above. If I plug in my USB JTAG cable, xmd fails to detect the cable. If I plug in a straight USB cable from my computer to the board, I get a listing of cable detection failures followed by this:

JTAG chain configuration

ERROR(201): Could Not Detect MDM Peripheral on Hardware. Check:

        2. MDM Core is Instantiated in the Design

I've tried specifying the -cable attribute, but it didn't seem to work.

Thanks.
