Nice. I checked the patch files but they're big and I missed anything obvious. I now see the pp_init_enable and hilariously a comment about hiding the diag commands.Nice find. after skimming through the patch files some more it turns out the secret mode is still there, they just renamed the routine and environment variable.
I defer to fohdeesha but for me, the other models using u-boot and Linux means Arris has to release their modifications. It's then "easy" (the u-boot patch is 400k lines) to go through their changes and find stuff they've hidden. In the case of Linux, it's easier to take their firmware images and open them to see the surrounding environment and how it boots. Actual hardware control however is still limited to FastIron and their kernel module. Those are proprietary and much harder to inspect, much less modify.Is there any way to leverage all the access we have with these dev builds to modify the firmware to allow for fan modifications?
The 6610 has none of this however. Someone else was working on a way to lie about the fan RPMs and I think that will be the quickest/only way to modify the fans.
