lsz would make board stuck after sending file.
File was transmitted successfully.
Actually board doesn't die, just the console dies, board still can be pinged through.
The following debugging information can help reproduced the phenomenon on board BF527-EZKIT:

This problem exist whether the toolchain version is 2013R1 or 2014R1 release.
If we use toolchain which compiled from git-a2bfd7b or git-46c6a72, the problem disappear when BR2_GCC_TARGET_CPU_REVISION in buildroot was set to 0.0.
If we set BR2_GCC_TARGET_CPU_REVISION in buildroot to 0.2, lsz also stuck the board.
lsz from uImage which BR2_GCC_TARGET_CPU_REVISION is 0.0 can work normally in linux which boot from uImage which BR2_GCC_TARGET_CPU_REVISION is 0.2.
But lsz from uImage which BR2_GCC_TARGET_CPU_REVISION is 0.2 always stuck the board in linux which boot from uImage which BR2_GCC_TARGET_CPU_REVISION is 0.0.
And execute file of lsz is different when BR2_GCC_TARGET_CPU_REVISION is different.
Different versions of lsz related file are in the attachment.
