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
|
|
|
|
|

- 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:
|
|
|
|
|
|
2012-11-25 22:57:04 +01:00
|
|
|
$ 0xFFFF -m initfs:initfs.jffs2 -f -r
|
2007-06-16 05:52:46 +02:00
|
|
|
|
2012-11-25 22:57:04 +01:00
|
|
|
The format of the argument is [[[device:[hw-revision:]]verion:]piece-type:]file-name[%layout-file-name]
|

|
|

|
2012-11-25 22:57:04 +01:00
|
|
|
Pieces can be automatically identified by using the '-i' flag:
|
2007-06-16 05:52:46 +02:00
|
|
|
|
2012-11-25 22:57:04 +01:00
|
|
|
$ 0xFFFF -m initfs.jffs2 -i
|
2007-06-16 05:52:46 +02:00
|
|
|
|
|
|
|
|
You can dump these pieces from the internal memory of the internet
|
|
|
|
|
tablet by using the mtd-utils over /dev/mtd* or just running:
|
|
|
|
|
|
2012-06-24 11:43:11 +02:00
|
|
|
770$ 0xFFFF -e /media/mmc1
|
2007-06-16 05:52:46 +02:00
|
|
|
|
|
|
|
|
There is another way for dumping pieces with extra parameters and options,
|
|
|
|
|
