The image neede to flash onto a Broadcom 63xx-series board depends on the board, method you are using to flash, and, for web-based flash, on the version of the Broadcom code your router uses. There are two major revisions of the Broadcom code as far as imagetags are concerned, before 3.08 and after 3.08, however there are some variations within in that, either due to vendor differences or due to changes at Broadcom (it's not clear yet which is the case). 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 code 2.21 is based on the BT Voyager firmware image I looked at. It may in fact be BT Voyager-specific. 2.21 is actually more difficult to deal with the imagetag from 3.00 as it has three different CRC calculations in addtition to the header CRC. 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 3.10 uses an imagetag that is believed to apply to all 3.10 and 3.12 versions, and has been tested on the Tecom GW6200. This version introdec changes to the imagetag to deal with TR69 (a remote rouer management system developed by the DSL forum). 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 |filename +-------------+-------------+---------+--------------------------------------- |any |cfe+most web | any |openwrt-<board>-<fs>-cfe.bin |AGVoIP2+WiFi |cfe |alice3.06|openwrt-AGV2+W-cfe-<fs>-cfe.bin |AGVoIP2+WiFi |web |alice3.06|openwrt-AGV2+W-cfe-<fs>-cfe.bin |CT536 |web |3.02 |openwrt-CT536_CT5621-<fs>-cfe.bin |CT5621 |web |3.02 |openwrt-CT536_CT5621-<fs>-cfe.bin |DG834GT |web |3.02 |openwrt-DG834GT_DG834PN-<fs>-cfe.bin |DG834PN |web |3.02 |openwrt-DG834GT_DG834PN-<fs>-cfe.bin |DSL-2640B |web |3.10 |openwrt-DSL2640B-<fs>-cfe.bin |DSL-2740B |web |3.10 |openwrt-DSL2670B-<fs>-cfe.bin |F5D7633 |web |3.10 |openwrt-F5D7633-<fs>-cfe.bin |F@ST2404 |web |3.0X? |openwrt-F@ST2404-cfe-<fs>-cfe.bin |F@ST2404 |web |3.1X? |openwrt-F@ST2404-<fs>-cfe.bin |GW6000 |web |3.00 |openwrt-GW6000-<fs>-cfe.bin |GW6200 |web |3.10 |openwrt-GW6200-<fs>-cfe.bin |Neufbox4 |web |3.12 |openwrt-NEUFBOX4-<fs>-cfe.bin |TD8810A |web |3.06 |openwrt-TD8810-<fs>-cfe.bin |TD8810B |web |3.06 |openwrt-TD8810-<fs>-cfe.bin |TD8811A |web |3.06 |openwrt-TD8811-<fs>-cfe.bin |TD8811B |web |3.06 |openwrt-TD881-<fs>-cfe.bin |TD8900GB |web |3.06 |openwrt-TD8900DB<fs>-cfe.bin |USR9108 |web |3.0X? |openwrt-USR9108-<fs>-cfe.bin |V2091_BTR |web |2.21 |openwrt-V2091_BTR-<fs>-cfe.bin |V2091_ROI |web |2.21 |openwrt-V2091-<fs>-cfe.bin |V2091_WB |web |2.21 |openwrt-V2091-<fs>-cfe.bin |V210_BTR |web |2.21 |openwrt-V210_BTR-<fs>-cfe.bin |V210_ROI |web |2.21 |openwrt-V210-ROI_WB<fs>-cfe.bin |V210_WB |web |2.21 |openwrt-V210-ROI_WB<fs>-cfe.bin |V2110 |web |2.21 |openwrt-V2110-<fs>-cfe.bin |V2110_AA |web |2.21 |openwrt-V2110-<fs>-cfe.bin |V2110_ROI |web |2.21 |openwrt-V2110-<fs>-cfe.bin |V2500V |web |2.21 |openwrt-V2500V<fs>-cfe.bin |V2500V_AA |web |2.21 |openwrt-V2500V-<fs>-cfe.bin |V2500V_SIP_CLUB |web |2.21 |openwrt-V2500V-<fs>-cfe.bin Old imagetag routers -------------------- Davolink DV201AMR Redboot routers --------------- Inventel Livebox Known router->code versions --------------------------- Vendor |Model |Code Ver ---------------------------+------------------------------------------+-------- Belkin |F5D7633 |3.10 British Telecom (BT) |Voyager V2091_BTR |2.21 British Telecom (BT) |Voyager V2091_ROI |2.21 British Telecom (BT) |Voyager V2091_WB |2.21 British Telecom (BT) |Voyager V210_BTR |2.21 British Telecom (BT) |Voyager V210_ROI |2.21 British Telecom (BT) |Voyager V210_WB |2.21 British Telecom (BT) |Voyager V2110 |2.21 British Telecom (BT) |Voyager V2110_AA |2.21 British Telecom (BT) |Voyager V2110_ROI |2.21 British Telecom (BT) |Voyager V220V |2.21 British Telecom (BT) |Voyager V2500V |2.21 British Telecom (BT) |Voyager V2500V_AA |2.21 British Telecom (BT) |Voyager V2500V_SIP_CLUB |2.21 Comtrend |CT-5261 |3.02 Comtrend |CT-536 |3.02 D-Link |DSL-2640B |3.10 D-Link |DSL-2670B |3.10 NetGear |DG834GT |3.02 NetGear |DG834PN |3.02 Neuf Cegetel |Neufbox 4 |3.12 Pirelli |Alice Gate Wi-Fi (+VoIP models?) |ag 3.06 Sagem |F@ST2404 |?
