Orange pi Zero WiFi 819 not works

Troubleshooting
#1

The built-in WiFi module in Orange pi Zero does not work.
With an external 802.11n USB Wireless LAN Card (MediaTek, Inc. RT2870) the module works.
How to solve this problem?

#2

Hi,

Known issue, please see here for a workaround/fix:

#3

Created the daemon file /etc/systemd/system/xradio_wlan.service

Code:

Systemctl enable xradio_wlan.service

Systemctl daemon-reload

Reboot


…


dmesg | Grep xradio

[12.662315] xradio wlan power on
[13.167005] [XRADIO_ERR] xradio_load_firmware: can not read config register, err = -110.
[13.167045] [XRADIO_ERR] xradio_load_firmware failed (-110).
[13.503539] xradio wlan power off



On other images, XR819 works (there are two orange pirou modules, the “debian_server_For_OrangePizero_v0_9_2.img” image).

In these images there are files XR819*.bin.

And in the image “DietPi_OrangePiZero-armv7- (Jessie) .7z” the XR819 files are missing.

How this system can work with a chip, if there is no mention anywhere?

What am I doing wrong?
