Heh. Of all the hackerboards I tried, the odroid c2 was the fastest and is generally my default target these days.
The "chip" is coming along nicely but lacks network. The odroid c1 and rpi2 have been the most reliable. (I'm still looking for a board with a decent toslink port....) ... I just foolishly tried to update my linksys 1200ac, but... it turned out the cable modem behind it was acting up and I lost touch with it (lacking a babel pre-installed)... aha! (/me worms his way through multiple hops through another modem) It looks like my default command line, post install is basically: opkg install luci-ssl luci-app-sqm babeld kmod-sched-cake netperf The 1200ac still has bug https://bugs.lede-project.org/index.php?do=details&task_id=294&order=status&sort=asc&order2=severity&sort2=desc I triggered it with: root@apu2:~/t# flent -H 172.26.64.1 -t 'isitfixed' --te=download_streams=12 tcp_ndown Warning: Program exited non-zero (1). Command: /usr/bin/netperf -P 0 -v 0 -D -0.20 -4 -H 172.26.64.1 -t TCP_MAERTS -l 60 -f m -- -H 172.26.64.1 Program output: netperf: send_omni: connect_data_socket failed: No route to host Warning: Command produced no valid data.

I guess it's one way around bugs like this. On Fri, Dec 23, 2016 at 6:51 PM, Aaron Wood <[email protected]> wrote: > Excellent.
