hi all,
 
I got a problem that I cannot fix,when I am trying to compile uboot1.3.4 for my processer s3c2440.
===============================================================
root at john-desktop:/home/john/u-boot-1.3.4 #  /usr/local/arm/3.3.2/bin/arm-linux-
ar: libyt2440.a File format not recognized
 
-bash:/usr/local/arm/3.3.2/bin/arm-linux-ar:: No such file or directory 
 
===============================================================
libyt2440.a is a file under my board directory, I found nothing in it when I opened it.
 
I have no idea about this problem,any idea you guys?
 
any help is appreciated!
