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-<board>-<filesystem>-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. In that case the tagid is shared, but the filename of the generated +image reflects the router for which the image was created. + +router |method| codever |tagid |filename ++----------+------+---------+------+------------------------------------------- +|any |cfe | any |bccfe |openwrt-<board>-<filesystem>-bccfe-cfe.bin +|any |t/ftp | any |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +| |web |3.00-3.06|bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +| |web |3.08 |bc308 |openwrt-<board>-<filesystem>-bc308-cfe.bin +| |web |3.10-3.12|bc310 |openwrt-<board>-<filesystem>-bc310-cfe.bin +|CT536 |web |3.02 |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|CT5621 |web |3.02 |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|GW6000 |web |3.00 |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|USR9108? |web |? |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|USR9108? |web |? |bc310 |openwrt-<board>-<filesystem>-bc310-cfe.bin +|DG834GT |web |3.02 |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|V2500V |web |3.08 |bc308 |openwrt-<board>-<filesystem>-btvgr-cfe.bin +|GW6200 |web |3.10 |bc310 |openwrt-<board>-<filesystem>-gw6200-cfe.bin +|Neufbox4 |web |3.12 |bc310 |openwrt-<board>-<filesystem>-nb4-cfe.bin +|F@ST2404 |web |? |bc300 |openwrt-<board>-<filesystem>-bc300-cfe.bin +|F@ST2404 |web |? |bc310 |openwrt-<board>-<filesystem>-bc310-cfe.bin +|AGVoIP2+Wi|web |alice3.06|ag306 |openwrt-<board>-<filesystem>-agv2+w-cfe.bin + +Old imagetag routers +-------------------- +Davolink DV201AMR + +Redboot routers +--------------- +Inventel Livebox + +Known router->code versions +--------------------------- + +Vendor |Model |Code Ver +---------------------------+------------------------------------------+-------- +Comtrend |CT-5261 |3.02 +Comtrend |CT-536 |3.02 +Tecom |GW6000 |3.00 +Tecom |GW6200 |3.10 +Pirelli |Alice Gate Wi-Fi (+VoIP models?) |ag 3.06 +? |TD-88xx |3.06 +BT |Voyager V2500V |3.08 (?) +Belkin |F5D7633 |3.10 +Neuf ? |Neufbox 4 |3.12 +NetGear |DG834GT |3.02 +Sagem |F@ST2404 |? +USR |9108 |? |
