| 114 | 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL | |
| 115 | =========================================== | |
| 116 | 2.1. System memory map: | |
| 117 | Flash: 0x00000000-0x3FFFFFFF (1024MB) | |
| 118 | DDR: 0x40000000-0x7FFFFFFF (1024MB) | |
| 119 | SRAM: 0x80000000-0x8FFFFFFF (256MB) | |
| 120 | IP: 0xFC000000-0xFFFFFFFF (256MB) | |
| 121 | ||
| 122 | 2.2. For the initial bringup, we adopted a consistent memory scheme between u-boot and | |
| 123 | linux kernel, you can customize it based on your system requirements: | |
| 124 | Flash0: 0x00000000-0x00FFFFFF (16MB) | |
| 125 | DDR: 0x40000000-0x4FFFFFFF (256MB) | |
| 126 | SRAM: 0x80000000-0x80007FFF (32KB) | |
| 127 | IP: 0xFC000000-0xFC0FFFFF (64KB) | |
| 128 | ||
| 129 | 3. COMPILATION | |
| 130 | ============== | |
| 131 | 3.1 To create U-Boot the gcc-4.x-xx compiler set (ColdFire ELF or | |
| 132 | uClinux version) from codesourcery.com was used. Download it from: | |
| 133 | http://www.codesourcery.com/gnu_toolchains/coldfire/download.html | |
| 134 | ||
| 135 | 3.2 Compilation | |
| 136 | export CROSS_COMPILE=cross-compile-prefix | |
| 137 | cd u-boot | |
| 138 | make distclean | |
| 139 | make M53017EVB_config | |
| 140 | make | |
