[U-Boot-Users] Hi, I am new to U-Boot, how do I get started?
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.
Dear Christophe,

Please enter the "while (learning) { ... }" loop as documented in the "Porting Guide" section of the README. Post again when you have reached the "if (clueless)" clause in the "while (!running) { ... }" loop ;-)
Best regards,
Wolfgang Denk
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 Cheers, T.mike -----Original Message----- From: u-boot-users-admin@lists.sourceforge.net [mailto:u-boot-users-admin@lists.sourceforge.net]On Behalf Of christophe peyronnet Sent: Friday, September 03, 2004 6:41 AM To: u-boot-users@lists.sourceforge.net Subject: [U-Boot-Users] Hi, I am new to U-Boot, how do I get started?
