greetings,
as i know the boot loader is the start-up for most of controllers today. till now i just used the boot loader written by someone but i don't have any idea about it how to write it what are the things we have to include and what parameters we have to taken into account ? could any one explain it clearly how to write it at least explanation with example for arm controllers????
Thanks and Regards.
Hello,
what do you mean by the word of bootloader?
Is it the boot program which will download program to the flash memory and jump to reset routine?
Or is it a just start-up program?
If you image the former, you must define the target device.
What is the target device?
Best regards,

Here is a cool small explain about the bootloaders, in particular for ARM soc.More explains : WebHome < U-Boot < DENX
after often there are u-boot sources included in the SDK provided by the board manufacturer.
I hope this will be a track start for you
I don't want to know the bootloadter.
I think the message will be for harshan_behra.
yasuhikokoumoto For sure it was for harshan_behra.Sorry
sorry,
i mean start up code for the controller.
thank you and sorry,
i just confused actually i want information about startup the things which were written in assembly all those stuff i want to implement. but i don't know where to start. hope now you understand
Thanks and Regards
Hello harshan_behra,
if you would like to write your own startup code, the post Writing your own startup code for Cortex-M would be helpful.
If your target device is not Cortex-M, the post D-side prefetch Cortex-A8 might be useful.
Although both are not my posts, ...
