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: 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: 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-4.1-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-1.x.x make distclean make M5373EVB_config make 4.
