Summary

There are several ways to commit your firmware, or bootloader to NAND. These methods can update your Didj with a fresh firmware, or a modified one with proper packaging.

Caution Make sure your batteries are charged, or you have an A/C adapter. Also that you understand, there is a certain level of risk making these modifications. Make sure you read through it first, and understand what is being done, before proceeding. Its best to first test these methods with a known working firmware or bootloader. And reading through U-Boot NAND Flashing to make sure you can recover if things go wrong.

Prerequisites

Programs Needed

Terminal program: Hyperterminal or equivalent

Hardware Needed

Software Needed

  • DIDJ-0x000E0002-000001.lfp (bootloader)
  • DIDJ-0x000E0003-000001.lfp (firmware)

Update With Console Access

Using Built in Tools

This method will use a few built in programs that come with the Didj for updating the firmware and bootloader. You will need to copy, or create a folder, and certain files in it for this to work It is easiest to extract the folder from the lfp archives and modify it as needed.

Firmware

For firmware this method will install into the opposite partitions, than the one you are on, so if you are on RFS0, the update will be installed to RFS1. And the Didj will be configured to boot from that one.

The firmware folder should be named firmware-LF_LF1000.

Mount your Didj and copy you're prepared folder to the /Didj/Base directory on your Didj.

After loading your folder onto the Didj, its best to run the check program, to make sure it can find it.

On Didj

# fwcheck
/Didj/Base/firmware-LF_LF1000

This should return the path to your folder, indicating it was found.

Now you can run the actual update program:

# fwupdate /Didj/Base/firmware-LF_LF1000/ > /dev/console
Found /Didj/Base/firmware-LF_LF1000/
Package Integrity Test Passed
Installing kernel.bin in Kernel1 (mtd5)
Kernel install successful.
Installing erootfs.jffs2 in Linux_RFS1 (mtd6)
Rootfs install successful.
Switching from RFS0 to RFS1

Bootloader

The folder must be prefixed with 'bootstrap-' (ex. bootstrap-LF1000).

The only files that are needed are:

lightning-boot.bin
lightning-boot.md5

Check that the updater can find your folder.

On Didj

# blcheck
/Didj/Base/bootstrap-LF_LF1000

Then run:

# blupdate /Didj/Base/bootstrap-LF_LF1000 > /dev/console
Found /Didj/Base/bootstrap-LF_LF1000/
Package Integrity Test Passed
Installing lightning-boot.bin in LF1000_uniboot (mtd0)
Bootloader install successful.

Caution

  • If you keep getting the Tune Up screen after ejecting your device, you'll need to remove firmware-LF_LF1000/ and/or bootstrap-LF_LF1000 from /Didj/Base on the device. As it will keep thinking it needs an update.

Manually

This method is for the advanced user. You must understand the partition layouts. Copy your file to /Didj/Base and run the following commands:

flash_eraseall /dev/mtd0
nandwrite -p /dev/mtd0 /Didj/Base/lightning-boot.bin

Update With Out Console Access

Force Update with Custom SCSI Commands

This update can be done with out a console connection, and mimics how LFConnect handles the task. Both updates can be done at the same time. This is exactly like With Built in Tools except we trigger the Didj to run those commands for us, by giving our package a higher version number and telling the Didj to eject. This is nice if you do not have console access to the device.

There are two ways to do trigger the update with the eject command.

If you want to do both at the same time, load both folders into /Didj/Base then run the command to eject.

Bootloader

For bootloader create a folder in /Didj/Base called prefixed with 'bootstrap-' (ex. bootstrap-LF_LF1000)

It should have the same files as the lfp package.

Make sure meta.inf has a version number higher than Version="1.35.2.4222" or if you've changed the version number in your file system, higher than that one.

Firmware

For the firmware create a folder in /Didj/Base called firmware-LF_LF1000

It should have the same files as in LFP package DIDJ-0x000E0003-000001

Make sure meta.inf has a version number higher than Version="1.35.2.4222" or if you've changed the version number in your file system, higher than that one.

Trigger Update With SCSI Commands

Then run the SCSI Command C6 "Disconnect Ok", which will cause it to say its "Learning New Tricks" before saying its okay to disconnect your Didj.

Then turn the Didj off.

This processes causes the Didj state machine to look for a folder called firmware-LF_LF1000, if its a newer version, which is found in meta.inf and compared to /etc/version on the Didj, it will update the files with the new ones.

Trigger Update With OpenDidjConnect

This is a program that does the SCSI Commands for you. You just need to give it the action desired, and the drive letter (Windows) or device (Linux).

Mount your Didj and Assign it a Driver Letter if in Windows. Else use dmesg in Linux to find the /dev/? it is.

Prepare your firmware or bootloader folder, just like the SCSI Commands section. But instead of running those commands, use OpenDidjConnect instead.

On Host

$ OpenDidjConnect -d <drive_letter> -c eject

Which will cause it to say its "Learning New Tricks" before saying its okay to disconnect your Didj.

Then turn the Didj off.

This processes causes the Didj state machine to look for a folder called firmware-LF_LF1000, if its a newer version, which is found in meta.inf and compared to /etc/version on the Didj, it will update the files with the new ones.


Caution

  • If you keep getting the Tune Up screen after ejecting your device, you'll need to remove firmware-LF_LF1000/ and/or bootstrap-LF_LF1000 from /Didj/Base on the device. As it will keep thinking it needs an update.

Update With LFConnect

If you are using Windows, and have LFConnect installed, you may find this way suites your needs. There is no special programs or need to run commands on the device itself.
