Fiasco firmware pieces
======================
The firmware for the maemo devices is composed by a set of pieces containing
the required parts to update the whole system following a partition layout
defined by NOLO on the internal flash memory.
Nokia provides a blob packed with a proprietary format called 'FIASCO'. This
blob contains the following pieces:
- 2nd - for Cold Flashing
- xloader - first part of nolo
- secondary - second part of nolo (usb support and launches kernel)
- kernel - the kernel
- initfs - initial system that initializes everything and runs rootfs
- rootfs - the whole system image
Some of these pieces are versioned to match board specific features
(mostly xloader and secondary ones).
To flash an initfs partition and reboot:
$ 0xFFFF -m initfs:initfs.jffs2 -f -r
The format of the argument is [[[device:[hw-revision:]]verion:]piece-type:]file-name[%layout-file-name]
Pieces can be automatically identified by using the '-i' flag:
$ 0xFFFF -m initfs.jffs2 -i
You can dump these pieces from the internal memory of the internet
tablet by using the mtd-utils over /dev/mtd* or just running:
770$ 0xFFFF -e /media/mmc1
There is another way for dumping pieces with extra parameters and options,
read doc/dumping for more information.
