[U-Boot] Want to burn a u-boot to a customized board

[U-Boot] Want to burn a u-boot to a customized board

[narke]

Hi, List

I've just built an u-boot boot-loader based on the configuration of 
smdk2410.  I built this by using buildroot, without additional 
customizing and modifications.

My problem is, I want to use the boot-loader to boot another s3c2410 
board which is a customized board cannot found configurations in the 
u-boot source tree.  I don't have smdk2410 actually, I choose this board 
just for making a good starting point.

My customized S3C2410 board looks not a strange one, it have common 
components usually found on other S3C2410 boards, such as Flash, SD Card 
Socket, Serial Ports and Ethernet interfaces.

My question is, if I download the boot-loader I just built for smdk2410 
to my customized board, how much chance I can see it can boot the board 
with success?  At this step, I don't expect I can load a Linux kernel 
successfully, I just what to see it can boot and give me a prompt on the 
serial console.

How much is that possible?

Hi Narke,

every board has a specific include/configs/xxyyzz.h configuration file,
based on the board-specific memory map (where flash, sdram etc are mapped).

So, if you are not lucky enough that other similar boards use same memory
map and similar periferic hardware, you have to arrange new board 
specific files for this custom board.

Look inside similar boards configuration (include/configs/*.h) files 
with same cpu, and try to figure out a working mix for the custom board,
and read the important README file for help on this.

Start from the memory map, as flash and sdram addresses, it could be a
good starting point to have something working briefly.

Best Regards,
Angelo Dureghello

Angelo,

Many thanks!  Looking through the include/configs/mdk2410.h gave me many 
hints.  I will start from here.
