In addtion Pirelli modified +the Broadcom code, so Alice Gate models use a different imagetag than any +other vendor. + +The imagetag format for flashing via CFE is the same for almost all the +boards, and is the same for all images generated by the imagetag utility. +Images flashable using cfe are labelled openwrt---cfe.bin + +The imagetags for tftp/ftp flashing is based on Broadcom 3.00-3.04 imagetags +and is known to be correct as the source code GPL and is available for reading. + +Broadcom 3.00-3.02 flashing has been tested on Comtrend CT-5261, CT-536 and +Tecom GW6000, and is the version of the flashing that was present before the +imagetags were split by broadcom code version (early June 2009) + +3.04 is guessed to be the same as 3.00-3.02 based on available information + +Broadom 3.06 is thought to be the same as 3.00-3.02, however the only 3.06 +this author (Daniel Dickinson) has seen is the Alice Gate (Pirelli) firmware +which is known to be different due to vendor (Pirelli) modifications to the +Broadcom code. + +Broadcom 3.08 introduced changes to the imagetag to deal with TR69 (a remote +router management system developed by the DSL Forum). The version we are +using as 3.08 is based on the BT Voyager firmware image I looked at. It may +in fact be BT Voyager-specific, and may in fact not be 3.08, but modified 3.06 +and not apply to all 3.08 versions. + +Broadcom 3.10 uses an imagetag that is believed to apply to all 3.10 and 3.12 +versions, and has been tested on the Tecom GW6200. It is similar to 3.08. +There is a field for vendor-specific information, that at least in some cases +is not optional. It is based on the hexedit of a neufbox4 firmware image, the +information in https://dev.openwrt.org/ticket/4987, and the hexedit of a Tecom +GW6200 image. + +Some boards share the same tag format, but require vendor-specific fields in +the board.
