u-boot flow
 
Hi,
I need to first understand how u-boot works and then port it for my ARM processor.

Can any one tell me from where the execution of u-boot will START.

Looking at the directory structure /cpu , /board , /lib_arm ,etc.

I understand at the end u-boot passes the control to the kernel.

Where is that part : /lib_arm/armlinux.c or /common/cmd_bootm.c.

Considering LPC2468 ARM7TDMI processor.

I need a sequence from Board power on till Linux Boot Start.
Thanks
Niraj

You hijacked someone elses thread, and re-opened this thread, which is two years old...both aren't good things. And did you read the documentation provided in the response?? It answers your question.

Hi TB0ne,
Sorry,I didn't mean it 'the hijacking', just thought it would be nice sharing the aspect of solved thread.I just went through the documentation (FAQ's and readme),but didn't find much helpful,and i'm still reading other things,thanks for your reply

-Thanks
