    Orange Pi Zero /4.11.0-sun8i/ wlan0 is gone

    in Orange Pi Zero

    Some quick results on packet loss measured via tcpdump:

    Medium traffic for 60 seconds (using tcpdump  via ssh, i.e. tcpdump measuring (and driving) its own console output): 

    65149 packets captured
65198 packets received by filter
46 packets dropped by kernel

    negligible packet loss on kernel level.

     

    Full blast with speedtest-cli running in parallel to the above scenario: 

    111886 packets captured
113448 packets received by filter
1562 packets dropped by kernel

    less than 2% packet loss on kernel level.

     

    At least in this scenario the driver seems to be quite robust.

    Quick speedtest using speedtest-cli (I know, I know ...):

     

    Test 1 - 1,5m from AP, no walls 

    Testing download speed........................................
Download: 13.20 Mbit/s
Testing upload speed..................................................
Upload: 5.42 Mbit/s

    Upload is limited by the ISP connection, dowload isn't (100Mbit/s download, 6Mbit/s upload). Repeats show similar results.

    No/few error messages (xradio_wlan mmc1:0001:1: missed interrupt)

     

    Test 2 - 8m from AP, 1 wall 

    Testing download speed........................................
Download: 1.77 Mbit/s
Testing upload speed..................................................
Upload: 0.88 Mbit/s

    fairly terrible - no errors.

    I am fully aware that that there have been issues in the past with some peoples expectations regarding this driver.

    But this very thread shows that a significant fraction of users seem to be fine with its limited function and performance.

    The download page for the OPi Zero already provides ample warning regarding the "module quality".

    This type of crashes (aes-arm related) should have been fixed yesterday by this commit, so I would suggest to rebuild the kernel.

     

    Nice - that fixed it.

    BTW, this is what the log shows when connecting to an AP in the pathed 4.11 version based on fifteenhex' driver:

    Assiciation to an AP finishes successfully, but then the driver seems to fail returning a NULL pointer:

    Adding spoiler tags for code blocks messes up the formatting. Sorry.

    The issue isn't to get the driver loaded, it is that it is flooding dmesg with tons of those errors : 

    
xradio_wlan mmc1:0001:1: received frame has no key status

    ... and if you do a "ifconfig" the whole kernel is hanging ...

     

    Same here. I also used fifteenhex's code.

     

    I used this DTS:

     

    /dts-v1/; #include "sun8i-h3.dtsi" #include "sunxi-common-regulators.dtsi" #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/input/input.h> #include <dt-bindings/pinctrl/sun4i-a10.h> / { model = "Xunlong Orange Pi Zero"; compatible = "xunlong,orangepi-zero", "allwinner,sun8i-h2-plus"; aliases { serial0 = &uart0; /* ethernet0 is the H3 emac, defined in sun8i-h3.dtsi */ ethernet1 = &xr819; }; chosen { stdout-path = "serial0:115200n8"; }; leds { compatible = "gpio-leds"; pwr_led { label = "orangepi:green:pwr"; gpios = <&r_pio 0 10 GPIO_ACTIVE_HIGH>; default-state = "on"; }; status_led { label = "orangepi:red:status"; gpios = <&pio 0 17 GPIO_ACTIVE_HIGH>; }; }; reg_vcc_wifi: reg_vcc_wifi { compatible = "regulator-fixed"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-name = "vcc-wifi"; enable-active-high; gpio = <&pio 0 20 GPIO_ACTIVE_HIGH>; }; wifi_pwrseq: wifi_pwrseq { compatible = "mmc-pwrseq-simple"; reset-gpios = <&r_pio 0 7 GPIO_ACTIVE_LOW>; post-power-on-delay-ms = <200>; }; }; &ehci0 { status = "okay"; }; &ehci1 { status = "okay"; }; &emac { pinctrl-names = "default"; phy-supply = <&reg_vcc3v3>; phy-handle = <&int_mii_phy>; phy-mode = "mii"; allwinner,leds-active-low; status = "okay"; }; &mmc0 { pinctrl-names = "default"; pinctrl-0 = <&mmc0_pins_a>; vmmc-supply = <&reg_vcc3v3>; bus-width = <4>; cd-gpios = <&pio 5 6 GPIO_ACTIVE_HIGH>; /* PF6 */ cd-inverted; status = "okay"; }; &mmc1 { pinctrl-names = "default"; pinctrl-0 = <&mmc1_pins_a>; vmmc-supply = <&reg_vcc_wifi>; mmc-pwrseq = <&wifi_pwrseq>; bus-width = <4>; non-removable; status = "okay"; xr819: sdio_wifi@1 { reg = <1>; compatible = "xradio,xr819"; interrupt-parent = <&pio>; interrupts = <6 10 IRQ_TYPE_EDGE_RISING>; interrupt-names = "host-wake"; local-mac-address = [dc 44 6d c0 ff ee]; }; }; ...

     

    wlan0 is there - "iwlist wlan0 scan" shows available networks, but connecting causes a hanging system ...

    OK, somewhat obvious: forgot to set CONFIG_WLAN_VENDOR_XRADIO in the kernel config-file.

    This time compiling the kernel failed, partly due to the face, that the current "add-xradio-wireless-driver"-patch has not been updated to the 4.11 version.

    On 11.5.2017 at 0:41 PM, tkaiser said:

     

    The driver is still there (and ready for 4.11) but not included ..

     

    Nope, I do not think it is ... (e.g. missing parameter for  ieee80211_cqm_rssi_notify function etc.)

    Orange Pi Zero /4.11.0-sun8i/ wlan0 is gone

    in Orange Pi Zero

    Like the thread-starter I was happy with the xradio-implementation in 4.10 and would like wifi-support in 4.11.

    Taking the advice of jhpadjustable and tkaiser and attempted to built a 4.11 kernel enabling the xradio-related patch.

    The kernel works alright but there still is no wlan0.

    Syslog shows a failed attempt to modprobe xradio-wlan during boot and there is no xradio-module in /lib/modules/4.11.1-sun8i/net/wireless/.

     

    I am probably missing something ultra-obvious here ... can anyone help?
