rtl8192eu driver on GoFLEX Net (4.17.2)

Hello Bodhi!

Sorry, I have to bother you again, with such a problem.
I made a new thread, because I found that I have another device.
My WiFi device is an 'Bus 001 Device 004: ID 0bda:818b Realtek Semiconductor Corp.'
I have been trying to build a module for this device on my GoFlex Net, with Debian and Kernel 4.17.2 for about 30 hours, yet. But still it doesn't work.
I encountered multiple problems, with the weirdest of them being, that I have to add massess of symlinks for actually getting the compilation started.
For example, symlinks like: 'ln -s /usr/include/arm-linux-gnueabi/bits/* /usr/src/linux-headers-4.17.2-kirkwood-tld-1/include/bits/'
Same for asm, gnueabi, sys and so on. Why is this? Is there something wrong with the header files, or did I install them wrong?

Then, when I finally had gotten the git driver-packets (I tried about 5 different sources) to actually start compiling, the build stopped. Always with errors about missing declarations, non defined structs and so on. I guess the reason is that I simply 'replaced' all those missing header files by symlinks towards another file with same name, that I had found to be the best guess for a replacement. What could I do about this?
Thank you and have a nice day :)

ElMariachi,

I am away from home so it’s hard to see your problem clearly.

Which model of Realtek device is this, do you know for sure that is rtl8192eu?

Hello Bodhi, yes it is an 8192eu for sure.

lsusb tells me it's an 0bda:818b

lsusb
Bus 001 Device 004: ID 0bda:818b Realtek Semiconductor Corp.

And this table tells, that this device id is an 8192eu: https://wiki.ubuntuusers.de/WLAN/Karten/Realtek/
lsusb

RTL8192eu 	USB 	0bda:818b 	Realtek 	WEP WPA WPA2 	b/g/n 2,4GH

But besides this, I think that there is a general problem with the build setup, that I don't understand, yet, because the header files seem to be spread around so many folders, where they are not found by each other.

ElMariachi,

> Hello Bodhi, yes it is an 8192eu for sure.

It is already supported in the mainline kernel. Not sure which module you can load, though. I need to look at the source code to find out.

Perhaps also I need to configure it in 4.17.2-kirkwood-tld-1.

Perhaps not. I could not find the ID 818b in staging driver folder. Only 8192u driver.

Yes, this driver really is a pain. I think I have read somewhere, that it couldn't be included in the main branches, just because Realtek forgot to add a proper license.

I remember having compiled it from sources before, but with the older Kernel, not the 4.17.

ElMariachi,

Have you tried

apt-get update
apt-get upgrade

before compiling the module?

Yes, I do update adn dist-upgrade everytime, before doing any modifications.
Also I installed the header files and created like dozens of symlinks for making the header files being found.
But then I had errors about undefined structs and such from gcc.

I believe these errors came either because the symlinks I made where wrong, or because the driver might need some patches for working with the current kernel. I don't know how I could find out, which of both is the true reason, or where I would have to search for a patch.

I tried building the 5 most recent forks on github: https://github.com/search?utf8=%E2%9C%93&q=RTL8192eu and
also I have tried the dkms packet that someone made for Ubuntu with Kernel 4.3 there:https://forum.ubuntuusers.de/post/7323198, but there where build errors, too.
And then there's rtl8xxxu in the mainline sources. It's said to work with 8192eu somehow (but slow and unstable), but I could not build it, because when I tried cloning the kernel sources to my GOFLEX, the NAS obviouslly stalled for 2 days, until I pulled the power cord.

Before I hade created that masses of symlinks, I always got this error first:

PS:
After reading this, I am pretty sure it's a problem with the header files. But where does this problem come from? Why are the header files not matching each other, regarding their search pathes?

I have not tried comple it to see for myself, but looks like this is the case.

It is typical to see problem like this when header files are not found because the driver build did not set up correctly with the kernel headers and libraries you are building with.The best approach to track this down by yourself (if there is no active supports) is to try building with an older kernel that you know working and go from there forward.

How would I get an older Kernel onto the GoFlex/Debian?
Isn't there a better alternative for building?
What are you building on?

I watched some tutorial about Linaro toolchain, but they where all Android-Centric and depend on sources provided by the smartphone's vendor. How would I replace that part for a device like the GoFlex?

Thank you!

ElMariachi,

Look in the release thread:

This Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 is to keep in sync with kernel Linux-4.4.0-kirkwood-tld-1.

Hello!

I tried to get Kernel 4.4.0 working for some time now, but with no success. net console showed it booted fine, but after loading the kernel there was no network connectivity. I could not even ping the GoFlex, even with setting a static ip in /etc/interfaces.

So I installed Debian with the included Kernel 4.12.1 now, as it's at least somewhat older than the 4.17 kernel that I tried before.

Did you install kernel 4.4, or did you create a new 4.4 rootfs from the released tarrball?

I formatted the partition and freshly created the rootfs from Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2.

That should work.

The only thing I would look for is your router. Does it use MAC address to assign certain IP address range?

Also, mount the Debian 4.4 rootfs on another Linux box and look at this issue:

ElMariachi,

Please post the link for the driver source code or kernel patch (preferred). Perhaps I could try to include this in the kernel 4.18.4 that I am starting to build to see if I get these errors (I can't promise that I will spend lot of time, but my build environment should be a good test for this).

Hello bodhi!

The most recent driver sources for the 8192eu I have found are those by Mange: https://github.com/Mange/rtl8192eu-linux-driver. They are only patched for up to Kernel 4.15. though.

For building the dkms drivers I did the following changes:
1. Added an entry for the glofex net to the makefile:

ifeq ($(CONFIG_PLATFORM_GOFLEX), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_PLATFORM_TI_DM365
EXTRA_CFLAGS += -DCONFIG_USE_USB_BUFFER_ALLOC_RX
EXTRA_CFLAGS += -DCONFIG_SINGLE_XMIT_BUF -DCONFIG_SINGLE_RECV_BUF
ARCH := arm
#CROSS_COMPILE := /home/cnsd4/Appro/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-
#KSRC := /home/cnsd4/Appro/mv_pro_5.0/montavista/pro/devkit/lsp/ti-davinci/linux-dm365
#CROSS_COMPILE := /opt/montavista/pro5.0/devkit/arm/v5t_le/bin/arm-linux-
#KSRC:= /home/vivotek/lsp/DM365/kernel_platform/kernel/linux-2.6.18
CROSS_COMPILE ?=
KSRC:= /usr/src/linux-headers-4.18.4-kirkwood-tld-1/
KERNELOUTPUT := ${PRODUCTDIR}/tmp
KVER  := 4.18.4
endif

2. created a line for adding the goflex config in the makefile:

CONFIG_PLATFORM_GOFLEX = y

3. added an symlink that seems to be required:

ln -s /usr/src/linux-headers-4.18.4-kirkwood-tld-1/ /lib/modules/4.18.4-kirkwood-tld-1/build

4. and then get the following error:

I tried adding a symlink to /usr/include/arm-linux-gnueabi/sys/socket.h, but this just lead to hundreds more of missing files.
I don't know what's wrong with the header files. They are installed like the instructions say.



I have also seen someone offering compiled packages for the RasPi with Kernel 4.17, but he did not provide sources.

Also there's a driver in the kernel that is supposed to be a generic Realtek wireless driver, I think: https://github.com/torvalds/linux/tree/master/drivers/net/wireless/realtek/rtl8xxxu. But when I tried cloning the sources of this from the kernel, my GoFlex worked for like 3 days and then crashed, because it couldn't handle all the load.

ElMariachi,

I have not tried this compilation yet. However, here is my observation.

> Makefile:606: arch/armv5tel/Makefile: No such file
> or directory

> oot@debian:~/rtl8192eu-linux-driver# make
> make ARCH=arm CROSS_COMPILE= -C

ARCH=arm is correct.

> ./include/linux/if.h:28:54: fatal error:
> sys/socket.h: No such file or directory
> #include <sys/socket.h> /* for struct sockaddr.

I believe this file sys/socket.h is in glibc. So your build environment might have been not correct. It was because either the script is out-of-date, or the script expects it is already in your enviroment but could not find it.

Since you said you've already install build-essential, I think the script has problem.

-bodhi

And that's not the only problem. As soon as I symlink this file, there are literally hundreds more of missing header files; they are all at the wrong path. For example, a directory named 'armv5tel' does not even exist in the header's tree.

Do you mean one of your scripts for installing the header files?

ElMariachi Wrote:

No, I meant the build script. Somehow your glibc path is not there (or not right) so you could not find that header.

I have discovered that the same problem occur when trying other build scripts, like this one: RTL8188EUS_linux_v4.1.4_6773.20130222 (First sockets.h is missing and after fixing with a symlink the other missing files follow..)

What I have seen in the docs that where delivered with that driver sources, the build script was made for "PCLinuxOS".

I don't understand why this is, but it's the same problem with another source for another code. So the problem cannot originate in the source self, can it?
