1.
Install cross toolchain |
| |
|
• get gcc 2.95.3 and binutils 2.10 for Linux from the CD provided |
| |
|
• uncompress and copy them to /usr/local/arm/2.95.3 |
| |
|
• set path and environment variables
|
| |
|
$setenv GCC_ARM_HOME/usr/local/arm/2.95.3
|
|
| |
|
$setenv GCC_EXEC_PREFIX $GCC_ARM_HOME/lib/gcc-lib/
|
|
| |
|
$set path=($GCC_ARM_HOME/bin $path) |
|
| |
|
|
| |
2.
Install kernel source and patches
|
| |
|
$tar -zxvf linux-2.4.18.tar.gz
|
|
| |
|
$gzip -dc patch-2.4.18-rmk7.gz | (cd linux;patch -p1)
|
|
| |
|
$gzip -dc patch-2.4.18-rmk7-swl8.gz | (cd linux;patch -p1)
|
|
| |
|
$gzip -dc patch-2.4.18-rmk7-swl8-cy2.gz | patch -p0
|
|
| |
|
$gzip -dc patch-2.4.18rmk7-swl8-cy2-lc2.gz | (cd linux;patch -p1) |
|
| |
|
|
| |
3. Edit linux/.config to determine root file system |
| |
|
$cd linux |
|
| |
|
$vi .config |
|
| |
|
• 5 partitions (/dev/mtdblock0 ~ 4) in 32Mbytes NAND flash |
| |
|
• default root file system is /dev/mtdblock4 of 16Mbytes (root=/dev/mtdblock4) |
| |
|
• For different partition scheme, change partition table in drivers/mtd/nand/smdk2410.c |
| |
|
• For RAM disk, set CONFIG_CMDLINE="root=/dev/ram0 console=ttyS0" |
| |
|
|
| |
|
| |
|
$make oldconfig |
|
| |
|
|
| |
5. Build kernel |
