| 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 |
| make M54455EVB_i33_config, or - default to intel 33Mhz input clock |
