how to install this on openwrt ?

I wanted to build this driver for my pcDuino3B board which has a rtl8188EU wireless LAN card.
The SoC of pcDuino3B is sunxi7i A20 (arm). Version of the Linux Kernel I used is 6.0.2.
I modified the Makefile of the driver as below:
CONFIG_PLATFORM_I386_PC = n CONFIG_PLATFORM_ARM_SUNxI = y CONFIG_PLATFORM_ARM_SUN7I = y

At first, an error occurred saying "mach/sys_config.h is missing", so I copied "arch/arm/mach-sunxi/include/mach" folder from official linux-3.4-sunxi source code which doesn't appear in the mainline Linux Kernel source code to the driver's "platform" folder.
Then, it proceeds with another error saying "script_parser_fetch function was not declared". After searching on the web, I found that this function may come from some tools from sunxi which I didn't find somewhere.
The two errors both come from "platform/platform_ARM_SUNxI_usb.c".

I found another rtl8188eu driver by an unofficial maintainer:
https://github.com/lwfinger/rtl8188eu

The above driver can be built and loaded with the above Linux Kernel 6.0.2. But it cannot work properly on pcDuino3B with a long existed issue.

Is it possible to combine these two drivers together?

Thanks very much!

hi there
i use your wpa_supplicant.conf and the final command doesnt work ! ()
i change channel and ssid ; not work.

please help me.
(WN722n v3)
and then i use this config . but client dont connect to ap !

If I change the txpower to anything and start ap with airbase, I cannot connect with any device. I tested I now multiple times and this problem only occurs with modded txpower. Works perfect otherwise. This occurs for txpower greater than 1800.
Otherwise i also wasn't able to provide and internet access with anything great than the original 1600.

Just for your consideration (this example assumes x86/x86_64):

Of course for Pi would need to change Makefile. But the same basic steps should work. By the way, I have seen a couple of Makefiles that figure out the architecture, so you don't have to do the Pi specific tweaks of the Makefile.

Would not be to hard to create a install-driver and remove-driver scripts. If your are open to a PR?

Hi,
the driver was successfully built for OpenWrt using buildroot, but doesn't recognize my adapter (TL-WN 722N v3).
Seems like the module is loaded ok, but when inserting an adapter it fails to init.

First of all, let me say thank you for your excellent project. I've been looking for a project like this for a long time and finally found this. It works fine with these steps on the RPi OS Buster which is available on the Raspberry Pi Imager as Raspberry Pi OS Lite (Legacy) and version of kernel is 5.10.103+.
But on the RPi OS Bullseye which is available as Raspberry Pi OS Lite (32-bit) and version of kernel is 5.15.84+, I got the below error:

Creating symlink /var/lib/dkms/rtl8188eu/5.15.84+/source ->
                 /usr/src/rtl8188eu-5.15.84+

DKMS: add completed.
Error! echo
Your kernel headers for kernel 5.15.84+ cannot be found at
/lib/modules/5.15.84+/build or /lib/modules/5.15.84+/source.
You can use the --kernelsourcedir option to tell DKMS where it's located.
rtl8188eu, 5.15.84+: added

The /lib/modules/ folder is as follows:

pi@raspberrypi:~/gc_setups $ ls /lib/modules
5.15.84+  5.15.84-v7+  5.15.84-v7l+  5.15.84-v8+  6.1.21+  6.1.21-v7+  6.1.21-v7l+

I can see there are unexpected folders for kernel version 6.1.21 created. Also, in the collect folder 5.15.84+ is as follows:

pi@raspberrypi:~/gc_setups $ ls /lib/modules/5.15.84+
kernel             modules.builtin            modules.builtin.modinfo  modules.devname  modules.symbols
modules.alias      modules.builtin.alias.bin  modules.dep              modules.order    modules.symbols.bin
modules.alias.bin  modules.builtin.bin        modules.dep.bin          modules.softdep

There was neither a build folder nor a source folder.

On the contrary, in the 6.1.21+, the build folder was created:

pi@raspberrypi:~/gc_setups $ ls /lib/modules/6.1.21+
build

I guess that as if the dkms is confusing as the kernel version of 5.15.84 and 6.1.21 but no idea why.

Do you have any suggestions on what I've missed steps or how I can fix it? Thank you for your kind help.

Any help?

Hi,

Thanks for the project!

Are there a list of differences with the vanilla Edimax drivers you have used as base?

Compiled fine on Pi OS 11 32 bit (ARM), but on Pi OS 11 64 bit (ARM64), make fails? I am using rpi-update to latest firmware/kernel, and rpi-source to pull the very latest raspberry pi kernel headers to match rpi-update. As I noted above, this seemed to work fine under 32 bit, but hit the following error(s) under 64 bit. Any idea why? Should it not work under 64 bit?

Error detail...

I get the following error running make:

I like the driver since Its rtl8188eu for TP Link TL-WN722N working on latest kernel 5.18.x and the best part was LED was working, at least it has a job now to blink like how the v1 does. Great.

Hi again,
i ran into another problem while using my adapter in client mode on OpenWrt 21.02.0 r16279-5cc0535800.
Initial AP connection works fine but an attempt to change station (Edit->Save/Apply) leads to wireless authentication error and disconnection. The same goes to Restart or Disable/Enable radio via LuCI interface.

RTW: rtw_cfg80211_unlink_bss(): cfg80211_unlink AP-name!!
RTW: rtw_cfg80211_indicate_disconnect(wlan2) ,reason = 15
RTW: rtw_cfg80211_indicate_disconnect(wlan2) call cfg80211_disconnected, reason:15

Reason 15 means 4-way handshake timeout. But the same connection goes back online after reboot, so WPA key is valid. Also it's possible to revive a connection by reloading the module rmmod 8188eu insmod 8188eu.
Nevertheless, the situation when a client connection successfully established and its AP restarted does not lead to the issue.

Besides, there is no signal strength and bitrate shows up for the radio in LuCI Wireless Overview regardless of connection state. Though this is a minor compared to handshake timeout issue.

Yesterday I upgraded to kernel 5.19.0.26-generic and after reboot my TP Link TL-WN725N was not recognized. It has worked perfectly with Kernel 5.19 until now, including the latest patch release 5.19.0-23-generic.

I checked it is not an adapter failure after trying it on an old Mac running OS 10.13 - it still works fine.

System:
Ubuntu 22.10
TP Link TL-WN725N (V1)

I am currently facing a minor issue while attempting to load the 8188 kernel module with the product ID 8179 on OpenWrt. Previously, loading the kernel module with product ID 0179 worked seamlessly and performed perfectly on the same platform.

If the only issue lies in changing the product ID, could you kindly provide guidance on which file I should modify the product ID before cross-compiling the driver again in the context of OpenWrt?

when I try to do the blacklist command in the tutorial it gives me a Permission denied error, Im doing this on a Raspberry Pi 2B on Raspberry Pi OS bullseye
