How to update the Freeplay from Compute module 3 to Compute module 3+
#1
hope all is well, I just put together my new Freeplay tech board with compute module 3+ and the new add-on to the Boxy pixel dual analog sticks. I followed all instructions the doc attached below https://docs.google.com/document/d/13ztk8Kr4_ORlY7lxX8KTQxo5e22cAsnQaAz2oZtT_ok/edit?usp=sharing I’m currently using the same flash image from my previous Freeplay built. Just to make sure everything is working. However whenever I try to Hold the power switch on for roughly 10sec the Freeplaytech green light won’t start. I removed the Raspberry pi compute module several times from it slot thinking it was that. But every time I place it back into the slot and I hear a soft click which tells me it’s in place. 
I removed my old compute module 3 and placed into my new board and it’s working. The new compute module 3+ seems to be the problem. 
I flashed Freeplaytech latest .img and it working. How do I update my older .img so it can work with the new Compute module 3+?
Does the Compute module 3+ require different software from the regular Compute module 3?

I'm sorry about the slow response.  It is often difficult for us to reply during the weekend.

You should be able to get your old SD image up and running on the new compute module, but it can be a little tricky.   I would definitely recommend making a backup of the SD card before you proceed.  

Make sure that the Compute Module 3+ is a "LITE" version.

NOTE that there is a fair chance that this update will "break" the button driver, and you'll need to reinstall it.  That's not difficult, but you'll need so SSH in (or maybe use a USB keyboard) to fix that after the reboot.

Insert the original Compute Module 3.
Connect your Freeplay CM3 to the internet.

IF you want to, you may be able to skip the first part if you prefer not to upgrade as much stuff.  I'm not 100% sure if it'll work (depending on the current state of your operating system), but you could try it.  The script that fixes the button/joystick driver may also update your kernel.

=== FIRST PART / Updating Operating System and Packages ===
Boot up to the main menu.
Select "RetroPie"
Select "RetroPie Setup"
Select "Update"
At "Update Installed Packages" select "Yes"
At "Update the underlying OS packages" select "Yes"
WAIT
Select "Perform Reboot"
=== ===

=== FIX JOYSTICK/BUTTON DRIVER ===
Turn the machine back on.
SSH into the machine (OR connect a keyboard and then hit F4 to get to the command prompt) and type the following
cd /home/pi/Freeplay/mk_arcade_joystick_rpi/
./install.sh
sudo shutdown -h now
=== ===

NOTE!!!  If the fix joystick button driver process got a new kernel, it would likely work on the CM3+, but it would also likely need to be re-run, so do the "=== FIX JOYSTICK/BUTTON DRIVER ===" a second time if the buttons still don't work after rebooting.  I ran through this entire process while writing this response, and I had to do the joystick driver install twice.  The first time it downloaded/installed a bunch of stuff.  The second time installed the new driver.

the Compute module 3+ final turned on but the controllers are not working.
I did the cd /home/pi/Freeplay/mk_arcade_joystick_rpi/
./install.sh
twice and that did not work.
I did sudo dkms unstall -m mk_arcade_joystick_rpi -v 0.1.5.6
sudo dkms build -m mk_arcade_joystick_rpi -v 0.1.5.7
that did not work

Please try to post the output of these commands.

cat /etc/modprobe.d/mk_arcade_joystick.conf

dmesg | grep mk_arcade


I would assume that there is a problem with the conf file.


IF you want to try to re-install the joystick/button driver, you can do the following commands...

cd /home/pi/Freeplay/
mv mk_arcade_joystick_rpi mk_arcade_joystick_rpi__old
git clone https://github.com/TheFlav/mk_arcade_joystick_rpi.git
cd /home/pi/Freeplay/mk_arcade_joystick_rpi/
mv /etc/modprobe.d/mk_arcade_joystick.conf /home/pi/Freeplay/mk_arcade_joystick_rpi/mk_arcade_joystick.conf.bak
./install.sh

My earlier post mentioned how to upgrade. I’m sorry. I’m currently only on my phone, so reading/analyzing these long lines is quite difficult. I couldn’t see any obvious errors. The dmesg lines looked as if it were working. Did you use jstest? You should try it.

Do this command:

jstest /dev/input/js0

See more at https://github.com/TheFlav/mk_arcade_joystick_rpi

You can try this.

IF you want to try to re-install the joystick/button driver, you can do the following commands...

cd /home/pi/Freeplay/
mv mk_arcade_joystick_rpi mk_arcade_joystick_rpi__old
git clone https://github.com/TheFlav/mk_arcade_joystick_rpi.git
cd /home/pi/Freeplay/mk_arcade_joystick_rpi/
sudo mv /etc/modprobe.d/mk_arcade_joystick.conf /home/pi/Freeplay/mk_arcade_joystick_rpi/mk_arcade_joystick.conf.bak
./install.sh
