Aethra SV6044VWn - possible support?

For Developers
1

Hi everybody!

I found an old IAD sitting on a shelf and I would give it a try with OpenWrt. Since I'm quite a newbie for hacking and I cannot find any pre-existing topic on this router, I thought to start a new one and post all the information I could find by myself.
I hope someone with better knowledge would help me trying to boot openwrt on this device!

The device is an Aethra SV6044VWn used in Italy by different ISP to provide xDSL access and VoIP services.
It has a very useful console port on the back which I used to grab the informations and a compactflash card reader I presume I could use to store the openwrt I would try to boot.

The Processor (pardon me if the term is not correct) is a Freescale MPC8323E PowerQUICC® II Pro. I see that an mpc83xx was present in the SoC platforms (and was used as a target to compile images for OpenWrt Attitude Adjustment 12.09).

I think the xDSL chip is Lantiq (Infineon), so it should also be supported by OpenWrt.

The serial connection is 9600/8-N-1. The bootloader can be "paused" by typing 123456 at boot.

This is the bootlog I captured via serial (pausing the bootloader then resuming with boot command):

This is the "normal" bootlog:

For what I understand, the board has 64MB flash and 256MB of RAM:

These are the available commands for bootloader:

Which commands Could I use to grab more information (at bootloader prompt or ATOS-NT prompt)?

I add some pictures:

printenv and iminfo would be interesting, maybe it could be helpful for generating an image that might boot via tftpboot.

However I think most of the people here are experienced with ar71xx, ramips and brcm targets, and mpc83xx would require additional patching to make it work with the latest kernel.

So, at the moment, I'm afraid the chances are probably rather low for this device being supported any time soon.

These are the output for printenv and iminfo commands
