Introduction[edit]
This is going to be the Freetz-Alien for the Speedport W 503V MK, and the second Howto about coding a Freetz-Alien.
the first one was the FREETZ_TYPE_W504V_7270_V3, which we finished successful. We can reuse a lot from there.
A Freetz-Alien modifies an AVM firmware to build Freetz for an alien model. This is mainly used for Telekom-Derivatives.
This alien is more complicated, since the Speedport W 503V MK is a very limited and we only have older firmware for it.
Comparison[edit]
The first step is to find an AVM model which best matches the alien model.
For the w503vmk we use the 7270v3 again since it has the matching SoC and WLAN chipset.
Features[edit]
We only have half the RAM and Flash size, no DECT and FONS0 port and no USB-Host.
It will be hard to squeeze everything in the small Flash and we need a lot of Remove-Patches.

Hardware[edit]
The w503vmk also has a different FPGA. This means that we must adapt the FPGA-Bitfiles in the Alien-Script.
Firmware[edit]
For older models including the 7270v3 there are different firmwares for german and international variants of a model.
- The dumped international w503vmk firmware is 4.79-20300 using kernel 2.6.19.2
- We may have a 4.81 dump, which is not scanned yet, but nothing more recent
- The latest international 7270v3 firmware is release 5.53-27445 using kernel 2.6.32.41
Freetz supports building for international 7270v3 5.20+ and 5.50+, both using the same kernel.
Freetz supports building for german Annex B 7270v1 4.89 with matching kernel 2.6.19.2, but wrong WLAN drivers.
