Need some help compiling a driver

[Zebra]

Hi all,

I need to compile a driver for my OS Debian Squeeze 2.6.38 to get my WiFi stick running. Unfortunaley, I'm unable to locate and install the Linux headers successfully to compile it by myself (I've already spent a lot of time to fix it, searched for answers for my questions in several forums, asked my teachers, etc...).

I would be REALLY appreciated if somebody can help me out! Unfortunaley, I'm not allowed to post the link to the official driver here unless I have made 15 posts, so you have to google for it: It's the RTL8188CUS driver, you can find it by going to the offical Realtek homepage.

Thank you in advance!

2.6.38 is not the squeeze kernel. Where did you get that kernel from?

Refer to the debian wiki for installing the driver: rtl819x - Debian Wiki

You need a newer kernel (2.6.39) and non-free firmware.

I'm running a Singleboard-Computer, a "Foxboard G20" and I downloaded it from the developers homepage.

A newer kernel you say? This is weird, because the driver which I need is a "Linux driver for Kernel 2.6.38(and earlier)", at least it's described as such one.

Yeah that's pretty much it. My guess is that the module "r8712u" is the wrong one for my WiFi Stick, that's why I'm looking for a compiled version of 8192cu. If I'm trying to set wlan0 per "ifconfig wlan0 up" up, I get no response.

The Debian wiki has some instructions for getting that adapter working on Squeeze.

Alright, I'll give it a try!

It's me again,

I'm getting an error at Step 4 of the tutorial:

debarm:~# modprobe r8192s_usb
FATAL: Module r8192s_usb not found.

The wiki states which controllers are supported by the kernel driver included in the squeeze kernel and yours is not one of them. The kernel module you need is also not included in 2.6.38 - you need at least 2.6.39 for the RTL8188CUS support, so no luck there either.

The module you're trying to insert was removed form the mainline kernel in 2.6.37 (which is what the fatal error refers to) and replaced by r8712u (also covered in the same wiki page) which is actually being loaded according to the report you posted - but it looks like r8712u is not the correct module for RTL8188CUS which should use the rtl8192cu - which is not in your kernel version (this is probably why it's loading r8192s_usb).

If the 2.6.38 kernel you have is the one from squeeze-backports, and you already have the backports repo set up, just install the 2.6.39 kernel from there and reboot. The module should load and all should be well, you will still need to install wireless-tools and wpasupplicant then configure your device as required: WiFi/HowToUse - Debian Wiki

I'm unable to locate and install the Linux headers

The squeeze-backports repo may have the header pkg you're looking for:

Debian -- Package Search Results -- headers-2.6.38

If so, add this line to /etc/apt/sources.list file, then update:

 deb http://backports.debian.org/debian-backports squeeze-backports main

I'm getting an error at Step 4 of the tutorial:

debarm:~# modprobe r8192s_usb
FATAL: Module r8192s_usb not found.

Try r8192u_usb
