[U-Boot] [ Uboot code understanding guide ]
Hi All,
I have started working on uboot porting on beaglebone black. I want to learn the code flow of uboot code so that i can add necessary HOOKs for the porting and understanding the kernel and fs porting further.
i am new to uboot and linux so could you please let me know the way to start with the walk through of the code ?
Regards, Devarsh

What exactly needs porting on this board? Does UBoot not work right out of the box?

As it has been pointed out several times in the last few days: start at _start, and follow the flow... See also the archives.

Hey wolfgang,
I am trying to port uboot on beagle boneblack. Eventhogh uboot has support for beagle board(but not for BBB), I'd like to port uboot 2013.10 on BBB as 1 task of ubuntu porting on BBB.
There are omap Soc supprted code in uboot source but to understand the flow as a beginner is a bit more complex. I'd search for the similar details in the mailchain first. Thanks for your response. On Jan 27, 2014 7:56 PM, "Wolfgang Denk" wd@denx.de wrote:

Ah why a 3rd port? there's always two configs you can use on the BBB..
"am335x_evm" which supports: AM335x GP EVM AM335x EVM SK Beaglebone White Beaglebone Black
or the "am335x_boneblack" which is just a tweak of "am335x_evm" to support only the BBB
