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 - make M54455EVB_i33_config, or - default to intel 33Mhz input clock - make M54455EVB_i66_config, or - default to intel 66Mhz input clock - make - -5.
