db9_gpio_rpi Rpi2, Version 3

[dabone]

I’m trying to reload my retropie with the new version, but I can’t seem to get the db9_gpio_rpi driver to work.

Here’s the steps I’ve been using..

write out the image to the sd.
boot, then resize partition.
then the following

apt-get update
apt-get upgrade
rpi-update

after this I’m at version 4.1.9-v7+.

I then sudo retropie-setup and select setup/config and the gamecon & db9 drivers.
After install, I then try the command

modprobe –first-time db9_gpio_rpi map=0,0

which returns the error…

ERROR: could not insert ‘db9_gpio_rpi’: Exec format error

the kern.log shows

Oct 4 15:42:54 retropie kernel: [ 1065.925490] db9_gpio_rpi: disagrees about version of symbol module_layout

Any suggestions?

The wiki is a useful resource:

If you don’t run rpi-update does it work?

Ok, got it working.

Fresh install,
resize partition
reboot
apt-get update
apt-get upgrade
update the retropie-setup script
reboot
Then I installed the driver with no problems.

Thanks, I thought rpi-update was required.
