Hi,
im new to uboot. i need to know what software are required to incorporate
uboot for hardware based on ARM architecture. it would be great if i can get
the step by step procedure to incorporate uboot. what is the use of ELDK?
what are the files that needs to be customized and how to get the
information required?

Hi Vanee,

1) Use git to clone u-boot:
   git clone git://git.denx.de/u-boot.git  <your_repository_name>/

2) Read the README.  You might start at line 3923 "U-Boot Porting Guide"
<http://git.denx.de/?p=u-boot.git;a=blob;f=README;h=2a553c274c372b014075cf67387dea964bd0722d;hb=HEAD#l3923>

3) Read the DULG manual (it talks about a specific processor and board 
in places, but is mostly general purpose).
   <http://www.denx.de/wiki/DULG/Manual>

4) Port u-boot to your board.

5) ???

6) Profit!

It is a cross compiler suite.

All the information is available on the web + manufacturer's manuals.
You will have to read and understand it - U-Boot is free in the freedom
sense, but not free in that you have to invest your time to understand 
it.  You can trade off paying money for investing your time.

If you only add a new board, this is very easy and doesn't require a lot 
of work. Maybe
if you want to support particular peripherals that are not included in 
u-boot support you must
write codes. A good starting point is a board that is quite similar to 
your board and try to
support the console first and the relocation process (so the sdram). 
When the console and the
relocation code are ok, you are quite near the end.

I think the best information is the code and the mailing list and all 
the documentation that
you can find in denx site.

[U-Boot] Reg. working with uboot

[Vanee S]

Hi,
I want to configure u-boot for Armadillo board. When i try make all i get
the error
Generating include/autoconf.mk
arm-linux-gcc: compilation of header file requested
make: *** [include/autoconf.mk] Error 1
This error does not occur if i comment the line
'$(CC) -M $(HOST_CFLAGS) $(CPFLAGS) -MQ $@ include/common.h > $@.dep ; \'
in the Makefile. How to rectify this error without commenting the above
line? im using u-boot 1.3.2 version.
But, will this disable any of the features?
And, when i make all after commenting the above line
im get the error
"Assembler messages:
Fatal error: Invalid -march= option: 'armv4'
make[1]: *** [hrllo_world.o] Error 2
make[1]: Leaving directory '/usr/eldk/usr/src/u-boot-1.3.2/examples'
make: *** [examples] Error 2
Pls do suggest on what needs to be done.

Regards,
S. Vanee

Try using a more recent toolchain, and a more recent version of
U-Boot.

It may cause subtle failure modes as you don;t build the make
depencies corectly, then.
