hi, i have tried that patch.but when i compile the source for at91sam9260ek i am getting error that u-boot uses soft floating point where as libgcc.a in my cross-compiler tool chain uses hard floating point . but i compiled a working u-boot for at91rm9200dk using this tool chain, and here also -msoft-float option was given.
has any one faced this kind of problem before?
thanks & regards vibi sreenivasan

Getting the AT91 u-boot bootloader
To get the u-boot bootloader up and running on an AT91 product you have to go through the following steps:
identify on which u-boot revision the patches will apply
download the corresponding u-boot
# wget ftp://ftp.denx.de/pub/u-boot/u-boot-x.x.x.tar.bz2 # tar xvjf u-boot-x.x.x.tar.bz2 # cd cd u-boot-x.x.x
take the AT91 u-boot patch set and apply it on top of the original
u-boot:
# wgethttp://www.at91.com/repFichier/Project-218/u-boot-x.x.x_atmel_y.y.diff.bz2 # bzcat u-boot-x.x.x_atmel_y.y.diff.bz2 | patch -p1
You will now have a fresh copy of the AT91 u-boot.
