[edit] Using the Firmware Updater

It is aparent, like all of the Linkstations, that the firmware does not want to update the firmware if the LS-GL reports the same firmware version as the the one to be that's to be sent to the LS-GL (i.e. a modified firmware). The work around is to:

• Add to lsupdater.ini

[SpecialFlags]
Debug = 1

• Change in lsupdater.ini

VersionCheck = 1

to

VersionCheck = 0

• Open linkstation_version.txt in any text editor (i.e. vi). Edit either the BOOT=, KERNEL=, INITRD=, or ROOTFS= (this is the main firmware and filesystem) to choose what to update by changing the version to a higher number.
  • i.e. by setting rootfs to a higher number, the filesystem will get updated, but uboot, kernel, and initrd won't get updated.
• Steps originally drafted by Georg.

Note: We are not positive if only one segmet (i.e. rootfs) will get updated. This method must be fully tested to find this out.

jonli, should I move the following more technical part about Erics excellent work into a separate section? - Georg

[edit] Updater Specifications

• As EricC documented on the LS-GL side clientUtil_server handles the update process and replies to various "ACP"-Commands, which are similar for the LS-GL and the Kurobox:

• LSP Commands

8020 ACP_Discover

8080 ACP_FIRMUP2

80A0 ACP_?? Possible Password?

8A10 ACP_CMD

8B10 ACP_?? Sent after 8080 and contains the filename. TCP File transfer starts after reply

8B20 ACP_?? Sent after TCP file transfer

• LSP Responses

C020 ACP_Discover_Reply

COAO Reply of 80A0

CA10 ACP_CMD_Reply

CB10 ACP_??_Reply 8B10

CB20 ACP_??_Reply 8B20

CB21 Sent after CB20. Same format with data changes Update complete?

• KuroBox Commands

8020 ACP_Discover

8070 ACP_FIRMUP_END

8080 ACP_FIRMUP2

8090 ACP_Info_HDD

8A10 ACP_CMD

• KuroBox Responses

C020 ACP_Discover_Reply

• Looking at the command word

Bit 15 = 1

Bit 14 is 0 for command and 1 for reply

Bits 11 to 8 appear to be the command class

Bits 7 to 4 appear to be the command in the class.

Bits 3 to 0 appear to be a sequence number in the response.

• The updater on the LS-GL receives ziped images and tries to unzip them by testing for the following passwords
  • 1NIf_2yUOlRDpYZUVNqboRpMBoZwT4PzoUvOPUp6l
  • aAhvlM1Yp7_2VSm6BhgkmTOrCN1JyE0C5Q6cB3oBB
