Exec format error on modprobe

[peterlopen]

hi @Kimplul ,

thanks for your driver!

I tried to install and use hid-tmff2 and everything went smoothly until last step:
peter@dell:~/Projects/hid-tmff2$ sudo modprobe hid_tmt300rs modprobe: ERROR: could not insert 'hid_tmt300rs': Exec format error
Please, any idea what is wrong?

Thanks a lot.

peter@dell:~/Projects/hid-tmff2$ uname -a

peter@dell:~/Projects/hid-tmff2$ ls /lib/modules/$(uname -r)/extra
hid-tminit.ko hid-tmt300rs.ko

Full transparency, I haven't bumped into anything like this myself, so any info I can give is more or less just regurgitated from the internet.

Anycase, from what I can find, there are a number of different causes and fixes, see

Here for a compiler issue
Here for some other/out of date package causing issues
Here for an arch/platform issue

Here is also a person that claims running modprobe with --force sometimes works, but it seems somewhat risky. The kernel usually knows when not to load modules, and its opinions should be respected.

Could you run modprobe with the verbose flag (modprobe -v) and see if there is any output in the dmesg buffer? That could help narrow things down.

hi,

my bad. I compiled with older version of kernel, even before buying just to see how likely it is to work :)
looks good now

thanks again for awesome work!

Yeah, that'll do it. Glad you got it working, if you have any other issues or suggestions for improvements, just open up another issue, I'd be happy to help.
