I have wrote .sdef file and .mdef file to install ko file to wp76xx but it’s have an error:
insmod: can’t insert ‘/legato/systems/current/modules/wfx.ko’: invalid module format
wfx.sdef :
kernelModules:
{
/home/exars/workspace/legatoAF/legato-19.02.0/drivers/wf200/wfx.mdef
}
wfx.mdef:
preBuilt:
{
$LEGATO_ROOT/drivers/wf200/wfx-linux-driver/wfx.ko
}
how can i install .kofile to wp76xx modules
You can use insmod command
Here is an example on running kernel driver module
do you mean insmod command like this?
root@swi-mdm9x28-wp:/lib/modules/3.18.140/extra# insmod /lib/modules/3.18.140/ex
tra/wfx.ko
insmod: can’t insert ‘/lib/modules/3.18.140/extra/wfx.ko’: invalid module format
if yes, it’s same error
Can you try my example and see if the insmod ok or not?
Btw, did you compile with correct toolchain and kernel path?
how to check the toolchain and kernel path that i compile is already correct?
users@IStNX3-15HP038:~/ダウンロード/priority_test/high_priority$ scp high_priority_helloworld.ko root@192.168.2.2:/tmp
root@swi-mdm9x28-wp:/# insmod /tmp/high_priority_helloworld.ko
[28900.086521] high_priority_helloworld: version magic ‘3.18.44 preempt mod_unl’
[28900.101211] high_priority_helloworld: version magic ‘3.18.44 preempt mod_unl’
insmod: can’t insert ‘/tmp/high_priority_helloworld.ko’: invalid module format
is I do in correctly??
How do you compile the .ko ?
You need to modify the makefile with the toolchain path
I can compile your example code but cannot compile mine,why??
root@swi-mdm9x28-wp:/# lsmod
Tainted: G
high_priority_helloworld 1729 0 - Live 0xbf0b1000 (O)
brcmfmac 205451 0 - Live 0xbf150000 (O)
You can port your code to my helloworld driver, then you will know which line makes the problem
BTW, " version magic ‘3.18.44 preempt mod_unl’" means you did not use the correct kernel path and toolchain for compilation
I have got this error but i don’t what is wrong??

You can see here
Seems the warning is for idx as a negative value
it still got the error:

also this error:

I don’t see anywhere defining the “struct trace_print_flags”.
You should ask the vendor of the driver
Btw, you can try to add the struct manually
https://docs.huihoo.com/doxygen/linux/kernel/3.7/structtrace__print__flags.html
BTW, I can find the definition of “struct trace_print_flags” here inside the toolchain:
/opt/swi/SWI9X07Y_02.28.03.05/sysroots/armv7a-neon-poky-linux-gnueabi/usr/src/kernel/include/linux/ftrace_event.h
Probably you need to include this header file in your driver source.
insmod have an error :
root@swi-mdm9x28-wp:/tmp# insmod wfx.ko
insmod: can’t insert ‘wfx.ko’: unknown symbol in module, or unknown parameter
How about my kernel driver?
yes, it’s worked
