Cross Compiling uboot - devkit 8000
prabu
i am using Devkit 8000 board, i recently cross compiled my u-boot source
*'u-boot-1.3.3*' available in the TIMLL's provided CD.
i cross compiled using these steps,
*make CROSS_COMPILE=arm-none-linux-gnueabi- distclean
make CROSS_COMPILE=arm-none-linux-gnueabi- omap3devkit8000_config
**make CROSS_COMPILE=**arm-none-linux-gnueabi-** all*
and obtained the following error
*hello_world.c:1: error: bad value (armv7a) for -march= switch
make[1]: *** [hello_world.o] Error 1
make[1]: Leaving directory
`/home/dcsystem2/Desktop/tmp_usage/u-boot-1.3.3/examples'
make: *** [examples] Error 2
*what could be done to get the uboot compiled.
Regards,
Prabu.J

I guess you need a *old* version of ARM cross compiler.
In my experience,
1.3.3 is fail to be compiled with arm2009q3, arm2010q1
(I means CodeSourcery G++ Lite),
but can be compiled with *arm2007q3* only.

Website:
http://www.denx.de/wiki/U-Boot
Download release version source tarball:
ftp://ftp.denx.de/pub/u-boot/
And you also need newer version of linux-omap kernel
or you will not get to boot.
website: http://gitorious.org/devkit8000
get source by git plz...
$git git://gitorious.org/devkit8000/linux-omap-devkit8000.git
I used CodeSourcery G++ Lite arm2010q1.
And some commands for build:
# Make u-boot.bin
cd u-boot-2010.03/
ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make CROSS_COMPILE=arm-none-linux-gnueabi- mrproper
make CROSS_COMPILE=arm-none-linux-gnueabi- devkit8000_config
make CROSS_COMPILE=arm-none-linux-gnueabi-
# result: ./u-boot.bin
# Make uImage
cd linux-omap-devkit8000/
ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make distclean
make ARCH=arm devkit8000_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
# result: ./arch/arm/boot/uImage

I used latest Das U-Boot for DevKit8000

http://www.denx.de/wiki/U-Boot
Download release version source tarball:

And you also need newer version of linux-omap kernel

I am trying to update the devkit8000 kernel, from the git repo.
After pulling the latest updates , I tried to build the kernel but it does not boot.
I use the openembedded generated toolchain, so CROSS_COMPILE is arm-angstrom-linux-gnueabi-
I build the uImage using
mkimage mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d vmlinux uImage
And the u-boot the is shipped with the board, U-Boot 1.3.3-svn (Feb 4 2010 - 15:16:04)
same for the x-loader.
The system is configured to load u-boot and kernel from nand and the filesystem from mmc
## Booting kernel from Legacy Image at 80300000 ...
Image Name: Linux
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 6675907 Bytes = 6.4 MB
Load Address: 80008000
Entry Point: 80008000
Verifying Checksum ... OK
Loading Kernel Image ... OK
OK
Starting kernel ...
it stops here..
Thanks

Try to replace the shipped U-Boot 1.3.3 with newer Das U-Boot (latest 2010.06).
The Das U-Boot latest stable version source can be found at: ftp://ftp.denx.de/pub/u-boot/
The building commands ref.: http://elinux.org/BeagleBoard#U-Boot
e.g.:
make CROSS_COMPILE=arm-none-eabi- mrproper
make CROSS_COMPILE=arm-none-eabi- devkit8000_config
make CROSS_COMPILE=arm-none-eabi-
(compile with "Sourcery G++ Lite for ARM EABI")
Btw, I didn't use the mkimage tool for converting vmlinux to uImage, but just directly use "make uImage".

I'll try it out this afternoon. I'll still stick to arm-angstrom-linux-gnueabi..
Using the Makefile out of the git repo "make uImage" was not available that's why I used mkimage

this fixed the boot problem but I have now new issues with the u-boot environment.
I used u-boot from the git repo so
U-Boot 2010.06-00236-g7385c28 (Aug 03 2010 - 12:01:32)
can you post the environment for the 7" lcd?
Thanks
Fabio

or mine:
$ vi boot.cmd
--------------------------------------------------------------------------------
setenv bootcmd 'mmc init; fatload mmc 0 80300000 uImage; bootm 80300000'
setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rw rootwait vram=12M omapdss.def_disp=lcd omapfb.mode=lcd:800x480'
boot
--------------------------------------------------------------------------------
$ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Linux" -d ./boot.cmd ./boot.scr
--------------------------------------------------------------------------------
# In order to get 'mkimage' tool, you need to install 'uboot-mkimage' package
$ sudo apt-get install uboot-mkimage
fabio ferrario
Thanks
these bootargs look familiar to me, the lastest u-boot has a more elaborated scripting in the environment that allows ( I think so ... ) for multiple boot options at runtime
Using the boot.scr out of the MMC should work an I'll go for it, although I have u-boot and the kernel in NAND and the filesystem on the MMC

I am also working on the devkit 8000 board.
please provide linux kernel information, I am using 2.6.34 kernel.i compiled with arm-linux-2009.
I got same result it's not booted. I checked bdinfo(mach-id) in boot loader is differs from kernel.
so i loaded the u-boot.4.3 reload and boot the kernel.
