I've tried several methods in other answers including this one but couldn't find a solution. After my driver crashed, and after the shell comes back, normally I could remove the module and insert the changed module. But this time I can't.
$sudo rmmod axpu_ldd_kc
rmmod: ERROR: Module axpu_ldd_kc is in use
$sudo insmod axpu_ldd_kc.ko
insmod: ERROR: could not insert module axpu_ldd_kc.ko: File exists
Isn't there any commands to remove the kernel module and insert anew? I'm looking for a non-programming method.
