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)
|
ATA: 0x90000000-0x9FFFFFFF (256MB)
|
PCI: 0xA0000000-0xBFFFFFFF (512MB)
|
FlexBus: 0xC0000000-0xDFFFFFFF (512MB)
|
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:
|
Atmel boot:
|
Flash0: 0x00000000-0x0007FFFF (512KB)
|
Flash1: 0x04000000-0x05FFFFFF (32MB)
|
Intel boot:
|
Flash0: 0x00000000-0x01FFFFFF (32MB)
|
Flash1: 0x04000000-0x0407FFFF (512KB)
|
|
CPLD: 0x08000000-0x08FFFFFF (16MB)
|
FPGA: 0x09000000-0x09FFFFFF (16MB)
|
DDR: 0x40000000-0x4FFFFFFF (256MB)
|
SRAM: 0x80000000-0x80007FFF (32KB)
|
IP: 0xFC000000-0xFC0FFFFF (64KB)
|
|
3. SWITCH SETTINGS
|
==================
|
3.1 SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
|
SW1 Pin4: 0 - ULPI chip not in reset state or 1 - ULPI chip in reset state
|
SW1 Pin5: 0 - Full ATA Bus enabled, FEC Phy1 powered down
|
1 - Upper 8 bits ATA data bus disabled, FEC PHY1 active
|
SW1 Pin6: 0 - FEC Phy0 active or 1 - FEC Phy0 powered down
|
SW1 Pin3: 0 - Boot from Atmel or 1 - INTEL
|
|
4. COMPILATION
|
==============
|
4.1 To create U-Boot the gcc-4.1-32 compiler set (ColdFire ELF version)
|
from codesourcery.com was used. Download it from:
|
http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
|
|
4.2 Compilation
|
export CROSS_COMPILE=cross-compile-prefix
|
cd u-boot-1.x.x
|
make distclean
|
make M54455EVB_config, or - default to atmel 33Mhz input clock
|
make M54455EVB_atmel_config, or - default to atmel 33Mhz input clock
|
make M54455EVB_a33_config, or - default to atmel 33Mhz input clock
|
make M54455EVB_a66_config, or - default to atmel 66Mhz input clock
|
make M54455EVB_intel_config, or - default to intel 33Mhz input clock
|
