0xFFFF(1)

💖 NAME 💖

0xFFFF — Open Free Fiasco Firmware Flasher, version 0.9.

Okay bestie, welcome to the General Commands Manual page for 0xFFFF(1) — aka the Open Free Fiasco Firmware Flasher. It’s giving firmware-girlie excellence, and we’re getting into all of it. 🎀

✨ SYNOPSIS ✨

0xFFFF [options]

💻 DESCRIPTION 💻

0xFFFF is the Open Free Fiasco Firmware Flasher for Maemo devices. It supports generating and unpacking FIASCO images on your local computer, which is lowkey perfect for editing a Maemo firmware package for a future flash. It supports flashing any image type to a Maemo device via USB, and it also does “cold” flashing — which literally means flashing a dead device with an erased bootloader. 😭 There’s support for booting the kernel via USB without flashing to NAND, and also changing the configuration of a Maemo device (enable/disable R&D mode, changing HW revision strings, ...). Iconic.

0xFFFF is the alternative tool to the proprietary Nokia flasher-3.5 and fiasco-gen. It generates compatible FIASCO images and also accepts FIASCO images generated by Nokia fiasco-gen. No cap. 💅

🛠 Operations 🛠

• -b [cmdline] — boot default or loaded kernel (default: no cmdline).
• -b update — boot default or loaded kernel to Update mode.
• -r — reboot device.
• -l — load kernel and initfs images to RAM.
• -f — flash all specified images.
• -c — cold flash 2nd and secondary images.
• -x [/dev/mtd] — check for bad blocks on mtd device (default: all).
• -E file — dump all device images to one fiasco image.
• -e [dir] — dump all device images (or one -t) to directory (default: current).

⚙️ Device configuration ⚙️

• -I — identify, show all information about device.
• -D 0|1|2 — change root device: 0 - flash, 1 - mmc, 2 - usb.
• -U 0|1 — disable/enable USB host mode.
• -R 0|1 — disable/enable R&D mode.
• -F flags — change R&D flags, flags are comma separated list, can be empty.
• -H rev — change HW revision.
• -N ver — change NOLO version string.
• -K ver — change kernel version string.
• -T ver — change initfs version string.
• -S ver — change SW release version string.
• -C ver — change content eMMC version string.

🖼 Input image specification 🖼

• -M file — specify fiasco image.
• -m arg — specify normal image.

arg is [[[dev:[hw:]]ver:]type:]file[%lay]
dev is device name string (default: empty)
hw are comma separated list of HW revisions (default: empty)
ver is image version string (default: empty)
type is image type (default: autodetect)
file is image file name
lay is layout file name (default: none)

🧺 Image filters 🧺

• -t type — filter images by type.
• -d dev — filter images by device.
• -w hw — filter images by HW revision.

📦 Fiasco image 📦

• -u [dir] — unpack fiasco image to directory (default: current).
• -g file[%sw] — generate fiasco image with SW rel version (default: no version).

🌸 Other options 🌸

• -i — identify images.
• -s — simulate, do not flash or write on disk.
• -n — disable hash, checksum and image type checking.
• -v — be verbose and noisy.
• -h — show this help message.

🎛 R&D flags 🎛

• no-omap-wd — disable auto reboot by OMAP watchdog.
• no-ext-wd — disable auto reboot by external watchdog.
• no-lifeguard-reset — disable auto reboot by software lifeguard.
• serial-console — enable serial console.
• no-usb-timeout — disable usb timeout for flashing.
• sti-console — enable sti console.
• no-charging — disable battery charging.
• force-power-key — force omap boot reason to power key.

🧪 EXAMPLES 🧪

Via USB:

Identify device:

$ 0xFFFF -I

Load kernel & initfs and boot it with cmdline:

$ 0xFFFF -m initfs:<file> -m kernel:<file> -l -b "<cmdline>"

Flash kernel and reboot:

$ 0xFFFF -m kernel:<file> -f -r

Flash FIASCO image and reboot:

$ 0xFFFF -M <file> -f -r

Flash only kernel from FIASCO image and reboot:

$ 0xFFFF -M <file> -t kernel -f -r

Cold-Flash 2nd and secondary bootloaders:

$ 0xFFFF -m 2nd:<file> -m secondary:<file> -c

On device (need nanddump from mtd-utils):

Dump all images to current directory:

$ 0xFFFF -e

Dump all images to one FIASCO file:

$ 0xFFFF -E <file>

FIASCO packaging:

Show FIASCO image content:

$ 0xFFFF -M <file> -i

Unpack FIASCO image to current directory:

$ 0xFFFF -M <file> -u

Generate new FIASCO image image.fiasco from files xloader.bin, nolo.bin, zImage, rootfs and append device&version information (xloader for RX-51 hw revision: 2101 and 2102, version 1.0):

$ 0xFFFF -m RX-51:2101,2102:1.0:xloader:xloader.bin -m RX-51:2101,2102:1.0:secondary:nolo.bin -m 2.6.28:kernel:zImage -m rootfs -g image.fiasco
