Blackfin firmware loading

[Chuckles67]

AX-86U running Merlin 386.2_2. Found my Router was not providing internet connection over WiFi. I could log in to the Router GUI, and the router stated internet connection was up/working.

Did a power-off manual reboot and all good.

Looking at the logs for failure, this happens nine hours before the manual reboot:

The logs continue for another 15 seconds, general rebooting, then no logs until I did the manual power reboot nine hours later.

Similar logs from another user here: http://www.snbforums.com/threads/as...ta-stage-2-is-now-available.69116/post-650121

After manual reboot the logs do not show Blackfin B0 firmware loading. Anyone know what Blackfin B0 firmware does in AX-86U?

why do you care. The logs are normal

Simply trying to understand why the WiFi was not working (WiFi stopped supplying internet, but could still access local network).
