| 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) |
| IP: 0xFC000000-0xFFFFFFFF (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: |
| Flash0: 0x00000000-0x00FFFFFF (16MB) |
| DDR: 0x40000000-0x4FFFFFFF (256MB) |
| SRAM: 0x80000000-0x80007FFF (32KB) |
| IP: 0xFC000000-0xFC0FFFFF (64KB) |
| |
| 3. COMPILATION |
| ============== |
| 3.1 To create U-Boot the gcc-4.x-xx compiler set (ColdFire ELF or |
| uClinux version) from codesourcery.com was used. Download it from: |
| http://www.codesourcery.com/gnu_toolchains/coldfire/download.html |
| |
| 3.2 Compilation |
| export CROSS_COMPILE=cross-compile-prefix |
| cd u-boot |
| make distclean |
| make M53017EVB_config |
| make |
| |
