Wifi is another area ... we do our best but and this used to work somehow in the past ... probably its a problem with a wrong firmware since nothing else hasn't been changed. As soon as we get a working video acceleration and 3D on a modern kernel, this kernels is gone. That functionality is the only reason we keep it for download.
Chrissie Brown Posted May 13, 2018 Author Posted May 13, 2018 Ok. But Video Acceleration is the point for me, because i use it for Kodi Media Center. But for the moment, i can live without WLAN on this box, i can use LAN cable. Can i get video acceleration working on a newer Kernel, for example if i compile some librarys or other stuff? Regards, Chris.

Bootlin will develop required video codecs for 30.000 euros but it's not done yet. Then some changes to video driver might be needed, then implementation and debug ... few more months in the most optimistic scenario. 8 minutes ago, Chrissie Brown said: i can live without WLAN on this box This WLAN - when it works - is probably too slow for multimedia.
Chrissie Brown Posted May 13, 2018 Author Posted May 13, 2018 Quote This WLAN - when it works - is probably too slow for multimedia. Really? Never heard about such an issue. My Main Use ist Simple IP TV Plugin in Kodi, and when this works, i am satisfied. I think my DSL 16.000 is the limiting factor here? Should i use a USB Wifi Module in the meantime? Does this provide better performance? Cannot imagine.
Igor Posted May 14, 2018 Posted May 14, 2018 13 hours ago, Chrissie Brown said: My Main Use ist Simple IP TV Plugin in Kodi, and when this works, i am satisfied. Wireless chips on those boards are mostly low performance - all are 1T1R and N at best. It's probably enough for streaming video under optimal conditions. You have to pick 3rd party USB wifi module carefully since kernel 3.4.y is very old and most of the modern ones won't work there. A20 boards are not really the best choice for KODI so I would rather pick something else. A big step forward are already (cheap) H3 boards with dedicated Openelec or some Amlogics on a bit expensive side.
Chrissie Brown Posted May 14, 2018 Author Posted May 14, 2018 Thanks for the insight. I got this Banana Pi board cheap. I installed kodi and did some configuration. Everything, except the Wifi works so far, so it fits for me. For example, i bought a random IR Remote, switched it to a NEC compatible mode which is actually a LG Sat Receiver, did some Kodi Keyboard Mapping, and it worked out of the box. I also thought about Orange Pi Board, maybe in the future But i can also wait for a newer Kernel to appear.

Chrissie Brown Posted May 15, 2018 Author Posted May 15, 2018 Ok, finally i managed to resolve all issues and got USB Wifi and onboard Wifi working. At first, there is an issue about loading Firmware to USB Devices. This matters all devices, i testet two. To see this / fix this, do the following: Get a well-known Device like RT2800 compatible. Plug it in. You will see in dmesg: [...] [ 944.529335] usbcore: registered new interface driver rt2800usb [ 1005.163497] phy3 -> rt2x00lib_request_firmware: Error - Failed to request Firmware. [...] You can start # udevadm monitor --property and watch the events. No Firmware gets loaded. To fix this, i did: * clone firmware, maybe not neccesary / you can get firmware somewhere else git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git cp rt2870.bin /lib/firmware/ * install the missing Firmware loading script and install. Get it for example from: wget https://raw.githubusercontent.com/msekletar/udev/master/extras/firmware/firmware.sh cp firmware.sh /lib/udev chmod 755 /lib/udev/firmware.sh * change loading udev rule, edit file: /lib/udev/rules.d/50-firmwarerule # stub for immediately telling the kernel that userspace firmware loading # failed; necessary to avoid long timeouts with CONFIG_FW_LOADER_USER_HELPER=y #SUBSYSTEM=="firmware", ACTION=="add", ATTR{loading}="-1" SUBSYSTEM=="firmware", ACTION=="add", RUN+="firmware.sh --firmware=$env{FIRMWARE} --devpath=$env{DEVPATH}" * now plug in and out the USB Device, firmware gets loaded. See in dmesg. * further working demo / debug with iPhone as an access point, orignal commands # dmesg [ 173.237800] Registered led device: rt2800usb-phy1::radio [ 173.242351] Registered led device: rt2800usb-phy1::assoc [ 173.251511] Registered led device: rt2800usb-phy1::quality [ 212.394061] ADDRCONF(NETDEV_UP): wlx7cdd901d63cb: link is not ready [ 306.550771] wlx7cdd901d63cb: authenticate with 80:2a:a8:d7:d1:fe [ 306.603112] wlx7cdd901d63cb: send auth to 80:2a:a8:d7:d1:fe (try 1/3) [ 306.609799] wlx7cdd901d63cb: authenticated [ 306.647584] wlx7cdd901d63cb: associate with 80:2a:a8:d7:d1:fe (try 1/3) [ 306.667489] wlx7cdd901d63cb: RX AssocResp from 80:2a:a8:d7:d1:fe (capab=0x431 status=0 aid=1) [ 306.716286] ADDRCONF(NETDEV_CHANGE): wlx7cdd901d63cb: link becomes ready [ 306.719199] wlx7cdd901d63cb: associated [ 317.426175] wlx7cdd901d63cb: no IPv6 routers presen # cat /etc/wpa_supplicant/wpa_supplicant.conf network={ ssid="Chrissie's iPhone" psk="asdf1234" } # wpa_supplicant -i wlx7cdd901d63cb -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf -B # dhclient wlx7cdd901d63cb # ifconfig wlx7cdd901d63cb Link encap:Ethernet HWaddr 7c:dd:90:1d:63:cb inet addr:172.20.10.4 Bcast:172.20.10.15 Mask:255.255.255.240 root@bananapipro:/home/chrissie# ping 172.20.10.1 PING 172.20.10.1 (172.20.10.1) 56(84) bytes of data. 64 bytes from 172.20.10.1: icmp_seq=1 ttl=64 time=35.9 ms 64 bytes from 172.20.10.1: icmp_seq=2 ttl=64 time=30.4 ms The second issue is about the onboard wifi driver. If i blacklist the module, and modprobe it when the system has fully booted, it works. you can even automate this with rc.local See: resolve: blacklist module, load when system is fully booted via modprobe, race condition? # vi /etc/modprobe.d/blacklist.conf [...] blacklist ap6211 [...] # reboot # modprobe ap6211 # dmesg [...] [ 135.443706] [ap6211] Firmware up: op_mode=0x0001, Broadcom Dongle Host Driver mac=98:3b:16:e9:6c:36 [ 135.461025] [ap6211] Firmware version = wl0: Mar 10 2014 14:59:50 version 5.90.195.89.18 FWID 01-b13c09c7 [ 135.464100] [ap6211] Chip: a962 Rev 1 Pkg 9 # ifconfig [...] wlan0 Link encap:Ethernet HWaddr 00:90:4c:11:22:33 [...] * to make this permanent, insert the following to the end /etc/rc.local: # By default this script does nothing. sleep 5; modprobe ap6211 exit 0 Well Igor you said, this had worked somewhere in the past, and there havent been changed anything - this ist hard for me to believe. At least i worked it out - maybe this helps some other people :) Chris.
