| 3. COMPILATION |
| ============== |
| 3.1 To create U-Boot the gcc-4.x 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 M5475AFE_config, or - boot 2MB, RAM 64MB |
| make M5475BFE_config, or - boot 2MB, code 16MB, RAM 64MB |
| make M5475CFE_config, or - boot 2MB, code 16MB, Video, USB, RAM 64MB |
