I am trying to build ramdisk image and launch bootsplash image at boot time.
Steps I followed:
1. get splash image initrd.splash using splash binary.
...
8. results in initrd.gz
Now while compiling kernel image I am embedding initrd.gz into it. Here is what I am doing
You don't need nothing special for *embedded *, not external "MIPS initrd" on a 2.4 kernels.
It works just fine from the CVS.
1) Prepare your "ramdisk.img" with EXT2FS/other FS
2) gzip it.
3) Put this "ramdisk.gz" into the arch/mips/ramdisk/
4) Enable in the configfile :
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_INITRD=y
CONFIG_EMBEDDED_RAMDISK=y
CONFIG_EMBEDDED_RAMDISK_IMAGE="ramdisk.gz"
5) make . Kernel build system will find this image automagically.
6) Run this kernel (vmlinux) without a "root=" parameter.
There is example of my kernel bootlog:
...
Determined physical RAM map:
memory: 01800000 @ 00000000 (usable)
Initial ramdisk at: 0x801b1000 (593920 bytes)
...
RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize
...
RAMDISK: Compressed image found at block 0
Freeing initrd memory: 580k freed
VFS: Mounted root (ext2 filesystem) readonly.
...
root FS is mouned now as /dev/ram0
