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 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.
