| 107 | |
| 108 | 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL |
| 109 | =========================================== |
| 110 | 2.1. System memory map: |
| 111 | Flash: 0x00000000-0x3FFFFFFF (1024MB) |
| 112 | DDR: 0x40000000-0x7FFFFFFF (1024MB) |
| 113 | SRAM: 0x80000000-0x8FFFFFFF (256MB) |
| 114 | IP: 0xF0000000-0xFFFFFFFF (256MB) |
| 115 | |
| 116 | 2.2. For the initial bringup, we adopted a consistent memory scheme between u-boot and |
| 117 | linux kernel, you can customize it based on your system requirements: |
| 118 | Flash0: 0x00000000-0x00FFFFFF (16MB) |
| 119 | |
| 120 | DDR: 0x40000000-0x4FFFFFFF (64MB) |
| 121 | SRAM: 0x80000000-0x80007FFF (32KB) |
| 122 | IP: 0xFC000000-0xFC0FFFFF (64KB) |
| 123 | |
| 124 | 3. COMPILATION |
| 125 | ============== |
| 126 | 3.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or |
| 127 | uClinux version) from codesourcery.com was used. Download it from: |
| 128 | http://www.codesourcery.com/gnu_toolchains/coldfire/download.html |
| 129 | |
| 130 | 3.2 Compilation |
| 131 | export CROSS_COMPILE=cross-compile-prefix |
| 132 | cd u-boot-1.x.x |
| 133 | make distclean |
| 134 | make M52277EVB_config |
| 135 | make |
