Kali 2 @ H3 boards doesn't switch to monitor mode

y52

Tkaiser @ armbian tipped the solution, although the grain of salt is discovered after the drive is built.
Could the "kernel tainted" be resolved?

Could you provide output of this:

1. file 8189es.ko
   
2. modinfo 8189es.ko

Copy code

"kernel tainted" is usually harmless, check this http://unix.stackexchange.com/qu ... is-a-tainted-kernel

y52

The "kernel tainted" is  harmless, but I can't load the driver.
Any ideas?

I wouldn't say that tainted kernel is the reason, it's just a information. I don't see any reason why it doesn't work. I will try to use this driver in a few days. Maybe I will find out something then.

In fact, our attention went to a different direction. The error is :
ERROR: could not insert module 8189es.ko: Invalid module format

Hence the module's format is under scrutiny. Hopefully, you can troubleshoot it.

jernej

That's why I asked you for modinfo and file output. But their output seems ok.

Strange issue.  

I made another clean build disabling the default module in the

jernej

Ok, it seems that you have problems with version magic. This means that kernel thinks that module was compiled for different version, which is strange. I don't know much about this magic strings, but at least they should match in kernel version (3.4.110 vs 3.4.110-sun8i). Probably this is a result of crosscompiling. Ask again in Armbian forums.

I'm using a kernels which have this check disabled.

y52

Apparently, the magic version mismatch could be corrected with the setting
EXTRAVERSION =

http://linux.die.net/lkmpg/x380.html

I looked for that setting in the driver's tree, but unable to find it.

This setting exists in the
# /lib/modules/`uname -r`/build/Makefile
and it is empty.

As I understand it, this Makefile is the one used for the kernel building, not the module, hence it is not the one to correct.

Probably, it is not as complicated to resolve, provided to find where the setting is defined.
