segmentation fault on kernel 3.4.6

[drheiser]

cross compiled driver for arm kernel 3.4.6 (busy box on qnap nas). Compiling succeeds with lots of warnings. Tried to insmod new kernelmodul 88x2bu.ko, but I get a segmentation fault. dmesg says kernel oops. Any ideas?

dmesg:

Please check "Platform Related" flags in Makefile.

On ARM devices, the CONFIG_PLATFORM_I386_PC flag must be set as "n". And you have to set "y" to one of correct flag.

[drheiser]

Thank you, but I set CONFIG_PLATFORM_I386_PC flag to „n“ already and tried different ARM settings, recently CONFIG_PLATFORM_ARM_GENERIC.

Didn’t solve the problem, I assume the driver is not compatible with Kernel 3.4.6

Maybe yes. The upstream supports later Linux-4.7. And I forked the upstream to support later Linux-4.12.

[FomalhautWeisszwerg]

@drheiser This driver released by EDiMax seems to support Linux kernel 3.4.6. https://www.edimax.com/edimax/mw/cufiles/files/download/Driver_Utility/EW-7822ULC_Linux_Driver_5.2.4.3.zip

Please try it.

[drheiser]

thanks I tried it, but same issue. The driver compiles with a bunch of warnings, but the process runs through. I then load the driver modul with insmod. When the WLAN adapter is already plugged in I get a segmentation fault. If I first disconnect the WLAN dongle then the driver is loading without error, but the device is not detected when I re-connect the WLAN dongle.
