2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
|
||||
===========================================
|
||||
2.1. 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:
|
||||
SDR: 0x00000000-0x00ffffff
|
||||
SRAM0: 0x20010000-0x20017fff
|
||||
SRAM1: 0x20000000-0x2000ffff
|
||||
MBAR1: 0x10000000-0x4fffffff
|
||||
MBAR2: 0x80000000-0xCfffffff
|
||||
Flash: 0xffe00000-0xffffffff

5. COMPILER
|
||||
-----------
|
||||
To create U-Boot the CodeSourcery's version of the GNU Toolchain for the ColdFire architecture
|
||||
compiler set (freescale-coldfire-4.1-elf) from www.codesourcery.com was used.
|
||||
You can download it from:http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
|
||||
|
||||
compiler that you used - for example, codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M
|
||||
codesourcery_elf requires -MQ in rules.mk, old M68K 2.95.3 just -M

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
|
||||

|
||||
cd u-boot-1.x.x
|
||||
make distclean
|
||||
make M54455EVB_config, or - default to atmel 33Mhz input clock
|
||||

|
||||
