I have RPi 3 Model B V1.2 with Raspbian Jessie OS.

I want to reduce boot-up time of RPi, so the board can boot-up (get desktop screen on HDMI) as fast as possible.

Currently, it is 42 sec. approx after attaching the power to the board. After 42 sec. I get the desktop screen on HDMI. It is configured to autologin.

Using - Wi-Fi, Ethernet, USBs, HDMI, Serial, I2C and Audio.

Not using - Bluetooth, Camera and LCD/TFT Display.

What type of changes I have to make? and Where?

Please let me know.

  • Edit in the output from systemd-analyze time and systemd-analyze critical-chain. – goldilocks Sep 19 '16 at 13:09

try this:

systemd-analyze critical-chain

it will tell you how much time do you spend in each boot service

  • will look into this command and will stop those more time-taking services. – Jaymin Dabhi Sep 20 '16 at 5:56
