2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
|
===========================================
|
2.1. System memory map:
|
Flash: 0x00000000-0x3FFFFFFF (1024MB)
|
DDR: 0x40000000-0x7FFFFFFF (1024MB)
|
SRAM: 0x80000000-0x8FFFFFFF (256MB)
|
IP: 0xF0000000-0xFFFFFFFF (256MB)
|
|
2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and
|
linux kernel, you can customize it based on your system requirements:
|
Flash0: 0x00000000-0x00FFFFFF (16MB)
|
|
DDR: 0x40000000-0x4FFFFFFF (256MB)
|
SRAM: 0x80000000-0x80007FFF (32KB)
|
IP: 0xFC000000-0xFC0FFFFF (64KB)
|
|
3. COMPILATION
|
==============
|
3.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or
|
uClinux version) from codesourcery.com was used. Download it from:
|
http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
|
|
3.2 Compilation
|
export CROSS_COMPILE=cross-compile-prefix
|
cd u-boot-1.x.x
|
make distclean
|
make M5373EVB_config
|
make
|
