113 2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
114 ===========================================
115 2.1. System memory map:
116 Flash: 0x00000000-0x3FFFFFFF (1024MB)
117 DDR: 0x40000000-0x7FFFFFFF (1024MB)
118 SRAM: 0x80000000-0x8FFFFFFF (256MB)
119 IP: 0xFC000000-0xFFFFFFFF (256MB)
121 2.2. For the initial bringup, we adopted a consistent memory scheme between u-boot and
122 linux kernel, you can customize it based on your system requirements:
123 Flash0: 0x00000000-0x00FFFFFF (16MB)
124 DDR: 0x40000000-0x4FFFFFFF (256MB)
125 SRAM: 0x80000000-0x80007FFF (32KB)
126 IP: 0xFC000000-0xFC0FFFFF (64KB)
130 3.1 To create U-Boot the gcc-4.x-xx compiler set (ColdFire ELF or
131 uClinux version) from codesourcery.com was used. Download it from:
