U-Boot for FriendlyARM Mini2440 (s3c2440)
|
||||
|
||||
This file contains information for the port of U-Boot to FriendlyARM
|
||||
mini2440
|
||||
|
||||
All information about the board can be found on :
|
||||
http://www.friendlyarm.net/products/mini2440
|
||||
|
||||
To build u-boot : ./MAKEALL mini2440
|
||||
|
||||
Overview :
|
||||
--------
|
||||
FriendlyARM Mini 2440 SBC (Single-Board Computer) with 400 MHz Samsung S3C2440
|
||||
ARM9 processor. The board measures 100 x 100 mm, ideal for learning about ARM9
|
||||
systems. It's a low cost board.
|
||||
|
||||
Boot Methods :
|
||||
------------
|
||||
Mini2440 can boot from NOR or NAND.
|
||||
|
||||
Build :
|
||||
-----
|
