RTL8188EU Driver compilation failed

[jgrulich]

First I've installed the repo 'rtlwifi' with the firmware, but even the firmware rtl8188eufw.bin is in the firmware folder, it's not working. After some time googling, I've found some hints that the driver doesn't support the right ID 2001:3311.
I've found that it need to be recompiled. I've tried to compile the driver accordingly to this:

Code: (bash) [Select]

http://www.linux-hardware-guide.com/2014-06-06-d-link-go-usb-n150-usb-wifi-802-11n
I've installed 'make.tcz' and 'git.tcz' which are in repo, but I'm not able to locate the rest as
'build-essential' and  'linux-headers-generic' packages.
I've created the folder /lib/modules/3.14.4-piCore+/build
where it need to be compiled. Than 'make' generates:

Code: (bash) [Select]

make[1]: *** No rule to make target 'modules' .  Stop.
make: *** [modules] Error 2
Please be so kind and provide tutorial how to get the needed packages and generate the build.

Please try piCore-6.0beta2 release and install wifi.tcz There is rtl8188eu.ko.gz Check related messages at the end of dmesg and post it. The rtl8188eu.ko is a staging driver, so it may work or not. Also it may require a new firmware, but lets see it before building kernel module.

Hi Béla, thank's for reply.
I've tested the last distro Beta2 as proposed, but the same result.
New USB device found ... , but no driver, or module loaded and the ifconfig wlan0 responds "Device not found".
 I've tested to load the module manualy:

Code: (bash) [Select]

sudo modprobe r8188eu
reconnected the device, but no difference.
Than I've tested even remove the module and the rtlwifi firmware installation

Code: (bash) [Select]

tce -wi firmware-rtlwifi.tcz
and reload the module and recconected the device, but nothing happened.

I've found here:
http://www.raspberrypi.org/forums/viewtopic.php?t=62371
 that the module need to be updated accordingly to the core and that ID 2001:3311 is quite new and is available from the core 3.12.28+.
Please be so kind and update the module for the core 3.14.4.

The present driver in the "wifi" package core is dated 20131104 and the requested ID is dated from 20140908.

Wait for piCore-6.0rc1 with final kernel version and updated components, kernel and header sources and then review the case.
