[U-Boot-Users] Boot Loader Development - Information

[Srinivas G.]

Dear All,

 

I am new to this boot loader development. I am developing the boot
loaders. I have gone through the google about the requirements to be
considered while developing. I did not get the much information about
what the boot loaders consist. 

 

Could some one send me samples / links so that it helps me in moving
forward further?


Thanks and Regards,

Srinivas G

You've gone through the google.  Wow.

Did you try something like searching for "U-Boot Design Principles" ?

And then follow the very first link it presents?

They are software...

See above.

Dear Wolfgang Denk,

Thank you very much for your information.

> You've gone through the google.  Wow.

Actually I have gone through the following links.

I know they are softwares. I mean, I need the information about the role
of the boot loader, what will it initialize? I think, in general it
initializes  the memory controller, processor, board specific hardware
etc. This is also varies from board to board and CPU to CPU. That too,
the boot loader written for PC is different from a boot loader written
for an embedded board. In case of PC, the most of the functionality will
be performed by BIOS and then executes the boot loader from the MBR. In
case of embedded board, they do not have the BIOS to perform the initial
system configuration. I am looking into the embedded board boot loader.
I need the information about the role of the boot loader in embedded
board. 

I did not find any document related to the role of the boot loader. So,
could you please send me some useful information on it.

Thanks in advance.

Thanks and Regards,
Srinivas G

http://en.wikipedia.org/wiki/Booting ?

Hmm... The links, you've gone through seem to provide lots
of information. What exactly do you want to know regarding the boot
loader we develop (u-boot)?

Clemens Koller

Do you really think that anybody wants to do your homework *for free*?
It seems that you need a paid consultant in order to give you some
training and possibly also implements the bootloader itself. And please
keep in mind that this mailing list is not a general helpdesk but only
intended for *specific* questions, bug reports, recommendations, etc.
about U-Boot.

With best regards
