hi experters:

I'm a newcomer in U-boot, I want to understand the U-boot,but i don't know how to start!Anyone can help me ? Thanks, Peter wang

Hi Peter,

Start by looking in the u-boot code/documentation to see if your processor is supported. Look through boards using that processor to get a feel for what needs to be customized for a port.

See the DULG manual: http://www.denx.de/wiki/DULG/WebHome

Browse the source: http://git.denx.de/

Read the README: http://git.denx.de/?p=u-boot.git;a=blob;f=README;h=5cbe7c1e80daabeee8c43247db7041b999919025;hb=HEAD

(especially starting at line 3732 ;-) http://git.denx.de/?p=u-boot.git;a=blob;f=README;h=5cbe7c1e80daabeee8c43247db7041b999919025;hb=HEAD#l3732

Then come back and ask specific questions and we will give you more specific answers.

Best regards, gvb
