Goal

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

The PI3 offers the possibility to boot directly on a USB device and thus free yourself from the microSD card sometimes generating problems (corruption).

** The installation procedure is strictly identical to that on a microSD card, but it will make sure to own a firmware to day.**

For this, open an SSH connection. (if you do not know how, watch the installation on microSD: [Here] (https://jeedom.github.io/documentation/installation/fr_FR/index.html) )

vcgencmd otp_dump

grep 17:

You must get back:

17: 3020000a

If so, your PI3 is correctly configured to boot on USB. If he can not find anything, he will normally start on a map microSD.

If the return is different, you should simply make a change day.

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

then

sudo rpi-update

Then restart the PI3

sudo reboot

Important

To avoid power problems, opt for a mSATA SSD drive low consumption.

Tip

You can now install Jeedom by following exactly the same procedure with an SD card. [Here] (https://jeedom.github.io/documentation/installation/en_US/index.html)

Possible adjustments

The following remarks must be taken into account:

Important

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

If you have swap problems, you need to change it.
- Increase its size:
  - Change the size of the swap by opening this file:

<! - ->

sudo nano / etc / dphys-swapfile

Find the right parameter:

<! - ->

CONF_SWAPSIZE = 100

Change the value of CONF \ _SWAPSIZE to 1024, for example, and then restart:

<! - ->

sudo reboot

Change the call value to the swap.

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 the Pi3 to use the swap only when 10% of available memory remains (100 MB of Ram available):

<! - ->

vm.swappiness = 10

Then restart:

<! - ->

sudo reboot

** Disable bluetooth built-in as incompatible with the card GPIO zwave.me **
- Open the file concerned:

<! - ->

sudo nano /boot/config.txt

add the line:

<! - ->

dtoverlay = ft3-disable-bt

Make a clean stop

<! - ->

sudo halt

Unplug reconnect (no sudo reboot!).
