[U-Boot] u-boot for ARM

[Amandeep Bhullar]

Hello All,

I have an Atmel AT91SAM9263 evaluation board with an arm926ejs based 
processor. I want to configure U-boot for this and want to have a USB 
device boot option available too. Though the U-boot will be in NAND 
Flash but i want the board to boot from a USB device like a USB Flash 
drive etc.

I was reading the README and it talks about configuring a large number 
of options. Where do I define these options? In which file?

if i  just give the command
$ make arm926ejs_config
if comes with a message
make: *** No rule to make target 'arm926ejs_config'. Stop.

Can anybody help me in how to obtain a .bin file for my processor that i 
can load in NANDFlash and use this U-boot.

Many Thanks

Aman.

That's correct, 'make' is unable to find such target. You must specify
the target corresponding to your board, for example "make
davinci_dvevm_config", i.e. prefix preceding '_config' normally
indicate a platform's name.

Obviously, either you're responding wrong person.

Sounds like an adventure!

For your board the file with many of the defines is.

include\configs\at91sam9263ek.h

You need to type,
make at91sam9263ek_config
make

Also it's a good idea to have the environment variable 

CROSS_COMPILE

Set to point to your tool chain, as in

CROSS_COMPILE=\opt\mytoolchaintool\arm-elf-

where the directory

\opt\mytoolchaintool\

Contains your tools, such as arm-elf-gcc etc etc.

Can't help there, don't know if it's possible.  I do know that
you can boot out of NOR (parallel) and Atmel Dataflash (Serial).
I would suggest building the standard u-boot and learn how it
works and then go from there.

[U-Boot] Loading Linux Image on AT91SAM9263-EK

[Amandeep Bhullar]

Hi All,

I have Atmel AT91SAM9263 Evlauation kit and want to load Linux-2.6.27 on 
it. Here is what I did:

1. Downloaded Linux-2.6.27 and followed instructions on 
http://www.linux4sam.org/twiki/bin/view/Linux4SAM/LinuxKernel to build 
the Linux kernel. I used cross tool chain arm-none-linux-gnueabi-
2. As a result i got file "vmlinux".
3. Converted it to binary using the command -     
arm-none-linux-gnueabi-objcopy -O binary -R .note -R .comment -S vmlinux 
linux.bin
4. Since U-boot uses only uImage, I gave command -    mkimage -A arm -O 
linux -C none -T kernel -a 200000 -e 200000 -n linux-2.6 -d linux.bin uImage
    This gave me the uImage file. I used Load address and entry point as 
0x200000 because it is suggested at 
http://www.linux4sam.org/twiki/bin/view/Linux4SAM/GettingStarted#Linux4SAM_NandFlash_demo_Memory 
that linux kernel should be at 0x200000 to boot from NANDFLASH. /Please 
comment if I built the image uImage file right?/

Now I want to use this Linux image on the AT91SAM9263-EK board. I use 
the Atmel tool SAM-BA v2.7. I erased the NANDFlash. Loaded Bootstrap and 
u-boot at the said addresses. It goes to U-boot prompt fine. The 
evluation kit is connected through serial port and I use hyperterminal. 
I get the U-boot prompt.

I have questions about loading the Linux Image. Do I just use SAM-BA 
v2.7 tool and send file uImage to address 0x200000? I tied that and I 
got Error: Cant get kernel image.

Any help will be appreciated !!

Aman.
