Hi, 
can Anyone point me to u-boot startup documentation. I am newbie to u-boot, infact new to bootloaders. 

I am using ARM7 core.

Good starting points are the DULG (http://www.denx.de/wiki/DULG/Manual),
and the README in the U-Boot sources (the current version could be found
here: http://source.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=README;h=09eb76fe4528dfedca027b119ac760fce2570e35;hb=HEAD)

Hi Bhagwat,
 
knowing one other bootloader, and being new to U-Boot, too, I welcomed
this article very much.
All things it says about bootlaoders in common is perfectly true.
http://www.informit.com/articles/article.aspx?p=674698&rl=1

This is a nice article about ARM core in case it aborts with an
exception, so you can trace back where it crashed:

Anja

HI all, 

I got the U-boot code and I am trying to compile it for my SOC. 
I am using ARM926EJS core. 
I have done follwing steps
1. In makefile I have added below lines 
        moschip_config :        unconfig
                    @./mkconfig $(@:_config=) arm arm926ejs moschip
2. I have copied header file in include dir
    $ cp include/configs/armadillo.h include/configs/moschip.h

3. Then I have copied dir
    $cp board/armadillo/ board/moschip/

after doing 
$make moschip_config
$make 

I am getting follwoing errs.. 
armadillo.c: In function `dram_init':
armadillo.c:58: error: `PHYS_SDRAM_1' undeclared (first use in this function)
armadillo.c:58: error: (Each undeclared identifier is reported only once
armadillo.c:58: error: for each function it appears in.)
armadillo.c:59: error: `PHYS_SDRAM_1_SIZE' undeclared (first use in this function)
make[1]: *** [armadillo.o] Error 1

Can anyone tell me, If i am missing any steps for compilation.

Hi Bhagwat,

This is the basic U-Boot porting process. Start with a reference board if
you can, copy files, make adjustments, attempt to compile, and then resolve
errors.

Part of the DRAM setup involves defining bank sizes. You need to declare
PHYS_SDRAM_1 and PHYS_SDRAM_1_SIZE in your include/config/moschip.h header
file. PHYS_SDRAM_1 should be the address of your SDRAM, and
PHYS_SDRAM_1_SIZE should be the size.

You will most likely encounter many different errors as you port U-Boot to
your board. Examine the error, look at the source, determine what's wrong,
and look at other working boards/configurations to figure out what you need
to do when required. If all else fails, post an e-mail here!

cheers,
Craig

[Bhagwat]

Hi
thanks for your response,
I am able to compile the code, but while linking at end ie after
        -Map u-boot.map -o u-boot
I am getting getting follwing errors.

net/libnet.a(net.o)(.text+0x108): In function `ArpRequest':
/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:234: undefined 
reference to `eth_send'
net/libnet.a(net.o)(.text+0x24c): In function `NetLoop':
/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:306: undefined 
reference to `eth_halt'
net/libnet.a(net.o)(.text+0x280):/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:318: 
undefined reference to `eth_init'
net/libnet.a(net.o)(.text+0x3e8):/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:400: 
undefined reference to `eth_halt'

I am not getting any pointer to this error, as I have not done any 
modification in /net folder.
Do I need to enable somewhere conditioanl compilation flag. please suggest.

regards,
__Bhagwat

Hi Bhagwat,

 If u have mentioned CONFIG_NET in your board config file then ethernet
related functions needed to be defined in your code. Have u defined
CONFIG_NET and other ethernet related defines in <board>.h in
uboot/include/configs/ directory.

Regards
Gururaja

Hi Bhagwat

   If u r working on arm926ejs, then i recommend u to check with versatile
config. its a very good starting point for arm926ejs. i too started with the
same. u can get good docs for this board from net. download the pdf and
check the memory map of versatile board and compare the same with versatile
config file inside include/configs directory. U will know how to setup ur
board.

Gururaja
