10 years ago What symbol is unknown? You can get that from the output of dmesg. My guess is that you missed something in the kernel configuration.
BTW, if you use kernel 3.12, this driver is built in.
MrEngman
commented
10 years ago Presumably the symbol is "schedule_work" that is described as undefined when the module is compiled. Checked dmesg and yes it is "schedule_work".
I try to maintain a set of compiled drivers, for wifi using 8188eu, for people using Raspbian on the Raspberry Pi. This is currently 3.6.11+ but is about to be updated to 3.10.18+ as rpi-update master branch has just updated to 3.10.18+, and I would like continue updating the compiled driver until it is include in the standard build. Rather like the 8188cus driver I used to compile and make available for people before that was included in the standard build.
Could be I've screwed up the configuration, just not sure how to figure out how if I have.
lwfinger
commented
10 years ago I just fired up my RPi that runs Raspbian and updated the git repo. I have switched to the 3.10.y branch and I am building 3.10.18. The kernel build started at 06:20 UTC on Nov 6. I do not remember how long it takes. I have never setup a cross-build system, and my sources are on an NFS volume, thus it takes a long time.
I'll let you know my results.

10 years ago Same Problem here: https://github.com/liwei/rpi-rtl8188eu/issues/4
Needs to adapt create_proc_read_entry and replace it with proc_create() and proc_create_data() and the use of seq_file facilities.

10 years ago Same problem here... I'm looking forward to the new, pre-compilled 3.10.18+ version of 8188eu. I really appreciate your efforts!
lwfinger
commented
10 years ago I finally got 3.10.18+ built for RPi. My version of the git repo had code for the driver.
In case my repo is different than yours, http://www.lwfinger.net/download/r8188eu_add_driver.patch will add the driver from scratch.
http://www.lwfinger.net/download/0001-staging-r8188eu-Update-driver-to-latest-version.patch will update what was in my repo to the latest version.
Whichever version you need to use, external firmware will be needed. http://www.lwfinger.net/download/rtl8188eufw.bin has the file.
MrEngman
commented
10 years ago Thanks for that. I'll let you know how I get on.

10 years ago Those URLs above should be lwfinger.com, not lwfinger.net. Sorry about that.

One thing I did notice on 3.10.18+ is that the ping times are very long. Is there something wrong with the USB layer?
I will try the latest version on the git repo to see if that makes a difference. I got my cross compiler fixed and I can build a new system fairly quickly.

10 years ago Hi Larry,
Thanks for your help fixing this problem on such a short time frame!
As a relative new Linux user I’m unsure what to do with these patches, is there a step-by-step procedure somewhere how to apply?
Or is there a pre-compiled 8188ey.ko file available to use, using the existing procedures?
Regards, Rob
lwfinger
commented
10 years ago No, kernel modules are quite finicky. They not only have to be built using the same configuration and headers as the underlying kernel, but they need to be built with the same version of the compiler. That means that you need to build it yourself.

10 years ago Where did you get those source files? My version has not had that daemonize call for some time.
One or the other of those patch files are meant to be applied to the Raspbian source so that you can build its kernel with driver r8188eu built in. The 3rd file is firmware, noit a patch.

I was able to compile OK as well but had the same problem and when I ran modinfo r8188eo.ko it said file was for 3.6.11+. I ran git checkout rpi-3.10.y to change from master to 3.10.y branch and now I get the error I decribed in previous post.
Very frustrating. Compile modules loads of time without problems until now.

I usually compile just the driver.ko but the format of the Makefile does not make this possible so I am having to compile the whole kernel. It’s taking a long time. Had another different error and had to restart the compile so no idea when it will finish, several hours I expect.

10 years ago Hi RobboRob,
It’s possible the problem is this.
Command uname –a shows “Linux raspberrypi 3.10.18+ #585 Thu Nov 7 15:16:15 GMT 2013 armv6l GNU/Linux” for my running kernel.
Command modinfo r8188eu.ko shows info “vermagic: 3.10.18+ preempt mod_unload modversions ARMv6” for lwfingers module, which includes “preempt”. So may be it’s compiled with a different format kernel – using preempt. Just a thought.

I was able to compile using some weird linux kernel headers I'd set up (for 3.10.18), but got Invalid exec format after using modprobe.
lwfinger
commented
10 years ago It was likely the weird kernel headers. To help all of you, I have created a copy of the repo with all the patching done. I am using 3.11.7 rather than 3.10.18, but you need to do the following:
git clone http://github.com/lwfinger/linux.git cd linux git checkout remotes/origin/rpi-3.11.y git checkout -b rpi-3.11.y git branch --set-upstream-to=origin/rpi-3.11.y rpi-3.11.y git pull cp config_save_3.11 .config make ./install_kernel

MrEngman
commented
10 years ago I haven't had, and don't have, problems with it (version from 27 Sept), and I am able to compile it as a separate module without compiling the kernel as it has a "proper" Makefile.
Would be helpful if you could restore the original format Makefile into the current version then it could be compiled without having to compile it with the kernel, and it will only take 10-15 minutes to find if it works or not. Compiling the new version with the kernel takes forever on the RPi and the module will not install for some reason. For me most recent error is "Invalid module format". Viewing modinfo data shows no difference to working modules so no idea why it fails to work.

10 years ago OK, finally sorted my problem with compiling for 3.10.18+, and now 3.10.19+. Mainly down to problems on my behalf and a certain lack of brain power, although there did seem to be some inconsistencies in the repos for linux and firmware which did not help. The Makefile problem was also mainly a lack of brain power, due to the Makefile in the patch file which was actually irrelevant for what I wanted to do.
Anyway for anyone interested in drivers, using the latest 19 Oct r8188eu source, for 3.10.18+ and 3.10.19+ read on.
