Raspberry Pi: move Root to USB

jivesinger · December 29, 2019, 12:44pm

As of the latest version of HassOS, USB boot is supported.
I’ve only very recently changed to a USB HDD for the same reason as yourself.

IMPORTANT:
Once you switch to USB booting, you are unable to go back to SDcard booting
This is a one way process

# Raspberry PI

Supported Hardware:

| Device | Board |
|--------|-----------|
| Raspberry Pi A+/B/B+| rpi |
| Raspberry Pi Zero | rpi |
| Raspberry Pi Zero W | rpi0-w |
| Raspberry Pi 2 B | rpi2 |
| Raspberry Pi 3 B/B+ | rpi3 / rpi3-64 |
| Raspberry Pi 4 B | rpi4 / rpi4-64 |

## Limitation 64bit

The 64bit version is under development by RPi-Team. It work very nice but it could have some impacts. Actual we see that the SDcard access with ext4 are a bit slower than on 32bit.

## Serial console

For access to terminal over serial console, add `console=ttyAMA0,115200` to `cmdline.txt` and `enable_uart=1`, `dtoverlay=pi3-disable-bt` into `config.txt`. GPIO pins are: 6 = GND / 8 = UART TXD / 10 = UART RXD.
