As your suggestion for me,Albert,I upgrade to uboot-v2011.06-rc3 by Git.This is the latest version i found on Git .And modified some places to make uboot buildable.Now arm-linux-readelf has no longer warns "segmentation fault", but after i burn u-boot.bin into flash,still nothing happened. I prefer to sending you a patch and readelf details that i generate with "git diff" and "arm-linux-readelf".

Patches as attachments are not really welcome on this list -- and as I said, patches which are not submissions for mainline inclusion should be avoided too.

Note that your patches have the added weirdness that many, if not all files in your patch have undergone attribute changes, with an addition of the "execute" flag that should never be set in a source code file. I suspect you are working on a Windows machine?

Also, then changes that are in your patch are strange: I can only see an addition in boards.cfg, based on what is there for B2, but nothing else. Is your board supposed to be so similar to B2 that le U-Boot baseline needs no change in the source code? But then, why would it need a change in boards.cfg?

Also, you should refrain from describing problems with "does not work" or "nothing happens". Clearly state what you do, how you do it, and then what you expect and do no get, or conversively, what happens that you did not expect.

Here for instance (assuming the code you're building is actually assumed to work with your board, which I cannot check), what exactly "does not happen"? What does the debugger tell you of the execution of the code? Does it go through the board_init_f calls sequence? Does it relocate? Does it enter the RAM execution stage?

I am a freshman with uboot.I found no book or something else introduce uboot.Even has DULG,but sometimes it was really helpless for me.Just like the problem i met ,i have no idea how to deal with.I suppose something wrong with linking stage or my cross-compiler.

I suggest you browse the mailing list archives for patch sets meant to add support for a new board and see how they are done and compare with what you did.

Because of attachment size limitation,i compress patch with bzip2. I suppose you can give me some advices.Thanks a lot.

Best regards larry

Amicalement,
