Preamble

If you want to have more space available on your SiMpad (SL4/SLC) you can delete your home partition.

THIS HOWTO IS ONLY FOR SL4 CLASS (32MB) DEVICES!!!

Needed steps

• You need to reallocate your partitions and change your "linuxargs".

boot> partition delete root
boot> partition delete home
boot> partition define params 0x40000 0x40000 16
boot> partition define root 0x80000 0x1F80000 16
boot> set linuxargs "mtdparts=sa1100:0x00040000@0x00000000(bootldr)ro,0x01f80000@0x00080000(root) noinitrd root=/dev/mtdblock1 init=/linuxrc console=ttySA0 rootfstype=jffs2 jffs2_orphaned_inodes=delete mem=64M"
boot> params save

This will add a 256KB big params partition in which the linuxargs can be saved. 256KB is a lot of space, but I think it's better to have a bit too much space then too low. Also a ~31MB root partition will be created and the params will be saved in the new params partition.

You can check your partition table with this one:

(Note: the 16 is now 10 hex the adresses are all in hex and in Byte)
