Dissecting a uRamdisk

In update packages, ramdisk.img is renamed to /boot/uRamdisk.

   1 # Skip 64-byte header
   2 dd if=ramdisk.img bs=64 skip=1 of=ramdisk.gz
   3 # Uncompress
   4 gunzip ramdisk.gz
   5 # Extract
   6 mkdir ramdisk
   7 cd ramdisk
   8 cpio -iv < ../ramdisk

Once modifications are made, you can recreate the image:

   1 find . -regex "./.*"| cpio -ov -H newc | gzip > ../ramdisk.gz
   2 mkimage  -A ARM -T RAMDisk -n Image -d ../ramdisk.gz ../uRamdisk
