3. COMPILATION
|
==============
|
3.1 To create U-Boot the gcc-4.x compiler set (ColdFire ELF 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 M54418TWR_config, or - default to spi serial flash boot, 50Mhz input clock
|
make M54418TWR_nand_mii_config, or - default to nand flash boot, mii mode, 25Mhz input clock
|
