Is your code in mainline?  Which board configuration si this?

[Otherwise: see http://article.gmane.org/gmane.linux.kernel.embedded/3534 ]

Really?  What are the exact problems? [Please post this on the ELDK
mailing list.]

Is this the exact error message?  And it gets printed by U-Boot?
Problem is, I cannot find any such text in mainline U-Boot.

The AT91RM9200 uses a ARM920 core, i. e. it belongs to the ARM9TDMI
family, ARMv4T architecture.

As the tool chain name "armv5te" clearly suggests, this is configured
for the ARMv5TE architecture (for example ARM9E, ARM10E, XScale
families).

So yes, this is configured for a more advanced architecture.  OTOH, if
you provide correct compiler options, it should still work for U-Boot.
But the, I don't know your code...

Best regards,

Wolfgang Denk
