we now main working on Linux 4.4, this is our development in progress

update : launcher have running success on linux 4.4 kernel ,maybe wifi will ready soon ,it is a hard work.:slight_smile:

Great! Looking good. The frequent updates really give confidence that support for the board is taken seriously. I just received my R2 boards and the hardware is very nice. Keep up the good work!

We have ported the wifi driver to Linux 4.4.70, now it’s working fine at 2.4G, please check https://github.com/BPI-SINOVOIP/BPI-R2-bsp/issues/1 for details.

WIFI 2.4G and 5G dirver have update ,anyone can help us to do some test ??

we test result at our office, But there is a balance issue at 5G mode, will focus on this issue right now

I did some WiFi tests with my Mikrotik RB435G AP, with 2x Atheros AR92xx WiFi adapter. One is configured for 2.4Ghz, the other one for 5Ghz. The BPI-R2 is about 1 meter away from the AP.

In both tests I first started iperf -s on my desktop and iperf -c <ip> on the BPI-R2. Then I did the same test the other way around.

2.4Ghz

Do you know when you build a new image of ubuntu with wifi drivers? I prepar a : IPS (suricata),DHCP and wifirouter(hostapd) but I wait a image stable for transfer to my bananapi

we had test 7615 module success

How to do auto power-on and auto start?

R2 won’t boot as soon as the power is supplied, but if you want to boot the R2 board without pressing the power button. There are 2 ways.

  1. You use a line to connect to the otg interface. or
  2. Modifying the hardware, you connect two points with ohmic resistors, pls check the location of two points by attachment

Hi gary. can you please make a higher-resolution picture on which we see the pins you mention. And the resistor (full circuit if not simply bridging 2 pins with resistor) value will be interesting.

we have try to test 720P software decode on BPI-R2, but not support 1080P .
