Illegal instruction error solution

Hello file compiled in the host machine when prompted to run in the target machine illegal instruction

My error is the cross compiler version problem I am using ARM926E V5 structure but cross-compilation installed The device is a friendly mini6410, the version is arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz belongs to the V6 structure of the ARM11 platform. May be incompatible.

Delete arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz corresponding decompression file (I don't know how to uninstall) after installing the corresponding 3.4.3 version of the cross compiler to compile, in The development board runs through.

At the end of the re-emphasis::: ARM9 and ARM11 cross compiler is not the same! ! ! ! ! !
