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

i am going to do this activity,if there is anyone who is already working on this please let me know.

vibi, this project already exists :-)

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:

1. identify on which u-boot revision the patches will apply

2. 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

3. take the AT91 u-boot patch set and apply it on top of the original

u-boot:

  # wget

http://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.

hello Remy, thanks for your support. the error i got is this

arm-linux-ld: ERROR: /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_udivdi3.oS) uses hardware FP, whereas u-boot uses software FP arm-linux-ld: failed to merge target specific data of file /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_udivdi3.oS) arm-linux-ld: ERROR: /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_clz.oS) uses hardware FP, whereas u-boot uses software FP arm-linux-ld: failed to merge target specific data of file /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_clz.oS)

and i solved this by commenting the "-msoft-float " option for compiler in cpu/arm926ejs/config.mk & cpu/arm926ejs/at91sam926x/config.mk

but what makes me think is that same flag was given for at91rm9200 and it worked.

thanks & regards

Hello vibi,

I have similar problems on the AT91SAM9261-ek, and I use a hack (attached) to be able to compile the code. It is not nice, but it worked for me until I (or someone else) have time to figure it out more deeply.

Maybe you have the same problem?

Kind Regards,

Remy
