Why don't you use current U-Boot code your new development?

And what the heck is GCC 2.4.6???

You still have to get it right.

See the FAQ why this doesn't mean anything.

Really? CFG_MONITOR_BASE != TEXT_BASE ? Are you sure about this?

Really? Not aligned to a sector boundary? Are you sure about this?

Really? Your U-Boot image needs nearly 2 MB ? Are you sure about this?

...as expected for a FAQ #1 entry question.
