ADB P.DG A4001N A-000-1A1-AX a.k.a. Telecom Italia ADSL2+ Wi-Fi N (AGPWI)
is a Telecom Italia braded router and it seems that there are no public
available unbranded versions of this router.
The stock Telecom Italia braded firmware has many partitions and the
partition layout changes with every firmware relase.
The PSI nvram partition is present in the stock firmware under the
"UNKNOWN" name but it's empty, full of FFs. Since removing partitions
does not cause problems with the stock firmware reflashing procedure,
I removed from the dts the PSI nvram partition from OpenWrt, expanded
the rootfs one and added the NVRAM partition contained in the
cfe bootloader.
Furthermore this router's flash needs to be entirely reprogrammed
and a new generic bcm6328 cfe must be flashed to boot OpenWrt. The
same process takes place when reflashing the stock firmware.
Here follows the original flash layout for AGPWI_1.1.0_013, the last
stock Telecom Italia braded firmware for which we have root
credentials (admin/riattizzati).

The last AGPWI firmware relase should be AGPWI_4.0.6 and it has much more
partitions than AGPWI_1.1.0_013.
The cfe partition in the stock firmware is 0x00020000 bytes long unlike the
OpenWrt dts in wich it's 0x00010000 bytes long because from 0x00010000 to
0x00020000 in the stock cfe there are only 00s and also because the cfe must
anyway be reflashed with a generic bcm6328 cfe 0x00010000 bytes long to
run OpenWrt.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
