insmod doesn't know where the source file is. If you put the complete
path name in the command, insmod should be able to locate the file. Try -
insmod
/lib/modules/3.8.13-00770-g97d16ab-dirty/kernel/drivers/gpio/gpio_test.ko

Hi all,
I am a newbie and following a number of forums to learn kernel
programming such as drivers, pin multilexing without using overlays or
device tree because I was comfortable with the previous kernel. Kernel
version is 3.8.
Well the small problem I am having is
I am using extra folder of derek molly's exploringBB repo. I tried to
compile gpio_test.c file as a module in bbb kernel in drivers/gpio folder.
*1) If I insmod this driver from home such as *
root@beaglebone:~# insmod gpio_test.ko
insmod: can't insert 'gpio_test.ko': No such file or directory
I get this error. So I have to go the particular directory
cd /lib/modules/3.8.13-00770-g97d16ab-dirty/kernel/drivers/gpio and
then do the insmod.
Why I can't load from home?
2)I am not getting log messages for this command
|tail -f kern.log
ta
tail: can't open 'kern.log': No such file or directory
tail: no files
why?*
