Raspberry PI 3

You will find here the documentation to install Jeedom on a raspberry PI 3 without microSD card.

The PI3 indeed offers the possibility of booting directly onto a USB device and therefore freeing yourself from the microSD card that sometimes generates problems (corruption).

The installation procedure is strictly identical to that on a microSD card, but you will need to make sure you have up-to-date firmware.

To do this, open an SSH connection. (if you don’t know how, watch the installation on microSD : Here

vcgencmd otp_dump | grep 17:

You have to get back :

17:3020000a

If so, your PI3 is properly configured to boot from USB. If it finds nothing, it will boot normally on a microSD card.

If the return is different, you just need to update.

sudo apt-get update; sudo apt-get install rpi-update

puis

sudo rpi-update

Then restart PI3

sudo reboot

IMPORTANT

To avoid power issues, choose a low-consumption mSATA SSD.

Tip

You can now install Jeedom by following exactly the same procedure as with an SD card. Here

Possible adjustments

The following remarks must then be taken into account :

IMPORTANT

The following changes are the result of problems encountered by users. You must adapt them to your case. Jeedom support does not intervene for problems related to your configuration.

• If you encounter swap problems, you should modify it.
  • Increase its size :
    • Change the size of the swap by opening this file : sudo nano /etc/dphys-swapfile
• Find the right setting : CONF_SWAPSIZE=100
• Change the value of CONF_SWAPSIZE to 1024, for example, then restart : sudo reboot
• Change the swap call value. By default, the system calls the swap when there is less than 40% of Ram.
• Open the file to change this setting : sudo nano /etc/sysctl.conf
• Add this line, to ask Pi3 to use the swap only when it has 10% of available memory (100 MB of available RAM) : vm.swappiness = 10
• Then restart : sudo reboot
• Disable built-in bluetooth because incompatible with the GPIO card zwave.me
  • Open the file concerned : sudo nano /boot/config.txt
• add line : dtoverlay=pi3-disable-bt
• Make a clean stop sudo halt
• Disconnect reconnect (no sudo reboot !).
