Hello every one ,
The linux system cannot get start on my board.
There are logs printed through the serial port
U-Boot 2012.04.01-00304-g7639205 (May 11 2013 - 15:43:39) DRAM: 512 MiB WARNING: Caches not enabled MMC: SDHCI: 0 Using default environment In: serial Out: serial Err: serial Net: zynq_gem Hit any key to stop autoboot: 0 Copying Linux from SD to RAM...

Uncompressing Linux... done, booting the kernel.
the system stopped here , booting the kernel failed.
What's the reason causing this kind of problem..
Hoping your help!

I have done some trial. And I make sure that the kernel is ok. Because it works well with the official BOOT.BIN file.
But when using my BOOT.BIN file , it never works .
and the system stop at here:
## Starting application at 0x00008000 ... Uncompressing Linux... done, booting the kernel.
The difference in the serial log file between the two situation is that
SD version 2.0 High Capacity: Yes Capacity: 3.7 GiB Bus Width: 4-bit
SD version 1.0 High Capacity: Yes Capacity: 3.7 GiB Bus Width: 1-bit
I am not sure if it is the problem.
Anybody may give me some advice??

Have you asked on zedboard.com?
That is the official support for the zedboard community.
Of course, you are welcome to ask here, also.

I suppose the BOOT.BIN file is the source of the error.
The BOOT.BIN is made up of the fsbl.elf, u-boot.elf and system.bit file. I have downloaded the system.bit file to the zynq , It successed.
So only the fsbl.elf and the u-boot.elf could be wrong.

I find another phonomenon: sometimes the BOOT.BIN file can configure the PL fabric.
sometimes it cannot.
I don't know why. For I use the same system.bit file
And I compared my generated BOOT.BIN file with the official file. The size of my is 4226KB, his is 4247KB. Dose this make sense.
Hoping your help!
