HI ,
I am newbie to U-Boot, I have a customized board with u-boot with it, I have seen through top level makefile of U-Boot.Below stated is what I have observed from makefile.
- First initialization of processor (ARM922t in my case) is
done in CPU folder with Startup.S where this assembly routine will call low_level_init code for initialization of RAM of customized board.
- Further I have observed rest all code which are required
for boot-up is made as library and compiled at once.
I would like to know how the code flow of U-Boot takes place , which are all the files which will be called in sequence while boot operation takes place, as far I have seen the code, Startup.S is one which starts first clearing Stack & PC which will further calls low_level_Init, I am unable to know how U-Boot works further from this place.
I would request U-Boot users to share there knowledge in explaining me how the code flow of U-Boot takes place, which will help me in finishing my project where RAM & Flash is changed.
Best Regards, Rajesh
