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 (64MB) |

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 M52277EVB_config |
