Cannot load driver

[nietoperz809]

Hi, I'm new to Linux. I successfully build this driver but can't get the 8188eu.ko to work.

sudo insmod 8188eu.ko ... says ... insmod: ERROR: could not insert module 8188eu.ko: Invalid parameters

uname -a says 5.4.0-kali4-686-pae #1 SMP Debian 5.4.19-1kali1 (2020-02-17) i686 GNU/Linux

sudo modinfo 8188eu.ko gives me ...

what am I doing wrong? What parameters are invalid? Thanks in advance for your help.

Seems to be a problem with my compiler/makefile setup? What can I do to fix that?

[nietoperz809]

I'm now trying to install the driver on a fresh Linux system. Maybe my cfg80211.ko is fucked up because I installed a monitor driver for rtl8187 before.

I'm now trying to install the driver on a fresh Linux system. Maybe my cfg80211.ko is fucked up because I installed a monitor driver for rtl8187 before.

did you blacklist the previous driver?

[nietoperz809]

Yes I did. Meanwhile I can load the driver. I have to manually load cfg80211.ko before. But it still didn't work. It won't enter monitor mode. Also the LED isn't blinking like in windows. The power-on routine is called but the firmware-download code not. I don't know why ....

[nietoperz809]

Meanwhile I got it running. Also monitor mode works, but the device name doesn't change to wlanXmon but remains wlanX. The only problem now is packet injection which causes a CPU exception (as shown by dmesg).

[hinell]

@nietoperz809 I'm experiencing the same problem with LED indicators. Would you like to create a separate issue on that?

[nietoperz809]

Hi hinell, there is a #define that is commented out. Sorry, I forgot name and .h file where it exists. The name is something with LED (all capitals). Scan all .h files for a define continuing LED and you'll find it. The identifier is pretty self-explanatory. Activate it and the LED will work just as in the windows driver.

[hinell]

@nietoperz809 Hi! I checked out two file called include/autocnfig.h include/rtl8188e_led.h and there is control directive called CONFIG_RTW_LED. I just have placed the following line into make file to see if it works:

   CONFIG_RTW_LED = y

I will report later on whether it works or not. Thanks.

Update : I did not work for me.

[sanqudui8ban]

kernel config has a item that called cfg80211 . if you set this item, the problem will be solved.
