Re: the way of making ramdisk image for smdk2410?

["dishui" <dishui@xxxxxxxxx>]

there's the document of my implementation, I hope it will be helpful

1.    make sure the bootargs env of Uboot looks like：
console=ttySAC0,115200 init=/linuxrc root=/dev/ram0
2.    kernel configuration:
Device Drivers  --->
        Block devices  --->
               <*> RAM disk support
 (16)  Default number of RAM disks 
               (12288) Default RAM disk size (kbytes)
 (1024) Default RAM disk block size (bytes) 
[*] Initial RAM filesystem and RAM disk (initramfs/initrd) support
       File systems  --->
              <*> Second extended fs support
3.    download the kenel & ramdisk image （initrd.boot），bootm kernel_addr ramdisk_addr
tftp 0x33000000 uImage ;tftp 0x31000000 initrd.boot;bootm 0x33000000 0x31000000
4.    to tailor the ramdisk image:
1) extract ramdisk.tar.bz2
2) dd if=/dev/zero of=initrd.img bs=1k count=12288
3)  mke2fs ?F initrd.img
4)  mount ?o loop initr.img /mnt/usb
5)  cp ?a ramdisk/* /mnt/usb
6) customize your FS in /mnt/usb
7)  umount /mnt/usb
8)  gzip -9 initrd.img
9)  mkimage -n "XXX ramdisk FS" -A arm -O linux -T ramdisk -C gzip ?d initrd.img.gz initrd.boot

Dear all:
 who can give me some suggestion  about making ramdisk image for smdk2410 board? website or guidline is OK.

Thanks a lot
