Disk Layout

The following was obtained by placing the HD into an ipod and using the ipod's emergency disk mode to gain an fdisk inspection of the drive's layout.

Disque /dev/sda: 60.0 Go, 60011642880 octets
64 têtes, 32 secteurs/piste, 57231 cylindres

Unités = cylindres de 2048 * 512 = 1048576 octets
Cela ne ressemble pas à une table de partition.
Probablement vous avez sélectionné le mauvais périphérique.

And translated into English (sorry for any mistakes -- AlexParker - 02 Nov 2007):

Loading code from Windows

Running code on the Gigabeat involves patching the original nk.bin file, inserting the custom binary executable, and using the patched Gigabeat V update utility to upload the new nk.bin file to the player.

What you need:

• mknkboot (see below)
• Windows Media Player 10 (required to detect the player)
• Patched Gigabeat V updater (download below)

Step 1

Compile (or use the precompiled binaries) and use the mknkboot tool (below) on a unmodified nk.bin file. A unmodified nk.bin file can be found in the patched Gigabeat V updater (nk_orig.bin). The mknkboot tool inserts the binary executable, and patches it to bypass the signature check. Usage :

mknkboot <firmware file> <boot file> <output file>

This will create a file in the current directory, which is what you need to upload to the player.

With the current build system for the Gigabeat S, the <firmware file> you should use is the nk_orig.bin file from the patched Gigabeat V updater. The <boot file> is bootloader/bootloader.bin after you've built the bootloader with the rockbox toolchain. This creates an original firmware image (i.e. with Windows Mobile) plus the Rockbox bootloader. Alternatively, you can skip the mknkboot step, and use the nk.bin file in the build directory. This doesn't include the original firmware however, and therefore dual-booting is not possible.

Step 2

For the gigabeat to accept the firmware update, it must either be in the recovery mode, or in the original firmware.
To enter recovery mode, HARD reset the player (turn off the battery switch and turn it back on), and hold left (on the cross, not '<--') and the windows button while booting to enter recovery mode. This will format the hard drive.
Performing the update from the OF will not format your player.

Step 3

Download the install.bat script and put it together with the modified nk.bin file in the same directory as the patched Gigabeat V updater. Connect the gigabeat to the computer and to the charger, and then run the install.bat script. Remove the usb cable when the updater is done, and the gigabeat will flash the new firmware (be careful not to remove the power while it's flashing), then run it. Once this is done when the Gigabeat is powered up again, if you want the Official Firmware to be loaded, you need to switch the hold switch on the device to the "On" position.

Loading code from Linux

What you need:

• mknkboot (in SVN)
• sendfirm (in SVN)

Step 1

Compile (or use the precompiled binaries) and use the mknkboot tool (below) on a unmodified nk.bin file. A unmodified nk.bin file can be found in the patched Gigabeat V updater (nk_orig.bin). The mknkboot tool inserts the binary executable, and patches it to bypass the signature check. Usage :

mknkboot <firmware file> <boot file> <output file>

This will create a file in the current directory, which is what you need to upload to the player.

With the current build system for the Gigabeat S, the <firmware file> you should use is the nk_orig.bin file from the patched Gigabeat V updater. The <boot file> is bootloader/bootloader.bin after you've built the bootloader with the rockbox toolchain. This creates an original firmware image (i.e. with Windows Mobile) plus the Rockbox bootloader. Alternatively, you can skip the mknkboot step, and use the nk.bin file in the build directory. This doesn't include the original firmware however, and therefore dual-booting is not possible.

Step 2

For the gigabeat to accept the firmware update, it must either be in the recovery mode, or in the original firmware.
To enter recovery mode, HARD reset the player (turn off the battery switch and turn it back on), and hold left (on the cross, not '<--') and the windows button while booting to enter recovery mode. This will format the hard drive.
Performing the update from the OF will not format your player.

Step 3

Compile the sendfirm tool (available in SVN in /utils/MTP), and use it to send the modified nk.bin file (produced by mknkboot) to your gigabeat. The sendfirm utility requires the libraries lib-mtp and lib-usb present to compile.

Usage:

sendfirm <file to send>

This will transfer the new firmware to the device (doesn't flash anything, much safer), and reset it, at which point it will then load the new firmware.

Note: The sendfirm tool is only meant to send either a patched nk.bin or a nk.bin compiled from the Gigabeat S bootloader. Anything else like a rockbox binary or tar will result in your device becoming non-functional. A format and restore is required.

Running Rockbox

Since we can only use MTP to transfer files we can not create a traditional .rockbox dir, however the bootloader is able to untar a rockbox archiv transferred using MTP.

To create the archive run

 make tar 

 mtp-sendfile rockbox.tar rockbox.tar 

The bootloader should then untar the rockbox directory and delete the tar afterwards.

To start rockbox, start the player with the "hold" switch engaged. To start the OF disengage the "hold" switch and reset using the battery switch.

Note: Before the bootloader was able to untar a complete rockbox build the single rockbox.gigabeat was transfered to the device. Since the first found 'rockbox.gigabeat' file will be used you have to delete rockbox.gigabeat first in order to update if you haven't used a complete rockbox.tar build before.

Mknkboot Gigabeat S Code Injection Tool

• mknkboot.c

This is a tool that bypasses the signature check, and will allow developers to insert their custom code into the Gigabeat S nk.bin firmware file.

Firmware Analyst

• Small firmware Analyst and extracted romimages of nk.bin: GigabeatSRomfiles.rar
• Extracted Eboot.bin (Bootloader): EbootBin.rar
• Extracted Recovery.bin (Recovery Image in case of Firmware load malfunction, ex. booting of unsigned code): RecoveryBin.rar

Eboot.bin and Recovery.bin were extracted with guidance from Zunepet. The dumprom utility was used written by Willem who extracted the kernel/firmware image.
