Make
sure you have a JTAG debugger (e.g. BDI2000)
Find a
board in .../include/configs that is close to your hardware
Make a
new board file in ...include/configs for your board
Copy
the starting board's files from .../board/xyz to your board's directory
.../board/myboard
With
JTAG device, verify, minimally, working RAM (where u-boot image
is
loaded), working serial port (for login and command line) working
Ethernet
for
network access.
Start
making same devices work under u-boot.
Hint,
try following this execution path... (arm)
.../cpu/at91rm9200/start.S
_start -> reset
reset -> _start_armboot
.../lib_arm/board.c
start_armboot -> (calls a bunch of init
functions)
enters forever loop calling main_loop
.../common/main.c
main_loop
Hope
this helps

Hello,
I am new to U-Boot, and I need to port it on an
custom board based on MPC852T.
As write in the Readme file of U-Boot directory,
I send my first e-mail to have some information, on
how to port U-Boot on my board.
Thanks in advance.
Christophe.
