[Cerowrt-devel] I have a Lantiq ADSL modem under OpenWRT; Willing to test cake

As someone on the periphery, I congratulate you in getting the TP-Link 
device flashed via a serial port. I bricked one, and moved to the 
Buffalo WMBR-HP-G300H, which has 32MB of faster flash.

Barrier Breaker is a very stable release for Lantiq devices. I had 120 
days uptime, and few retrains.

Cake requires a later kernel than Barrier Breaker, so you would need to 
reflash a device with 8MB flash over a serial link with a less stable 
build of Chaos Calmer.

If you intend to try cake, I suggest a device such as the one I mention 
would give you a quieter life. It is freely available in Europe: I do 
not know about the US.

I remember there being very little free flash on the TP-Link, as you say.

That TDW8970 is connected via an ethernet segment to a WNDR3700v2 running cero 3.10.50-1 (which is my router, leftover from using the junker DSL modem from my ISP that used to sit where the TDW8970 sits now).

As I understand their network topology, this isn’t a central office DSLAM, but a fiber-to-the-node thingy. The upshot is that unlike my last place with DSL to a central office, I have very stable line-sync rates with noise margins (as reported by luci) of about 38dB down and 28dB up. (If only Frontier would sell me a higher speed link, but I digress.)
> So, If there is any interest from the group in testing cake on such a marginal DSL configuration, I’m ready to give it a shot, but will need some instructions. Be aware that the TDW8970 is fairly constrained for overlay filespace — I currently have only ~800k free — so the install might be nontrivial.
