# ODROID-M1
|
|
|
|
Home Assistant OS 10 and newer support the ODROID-M1 board.
|
|
|
|
## SD-card
|
|
|
|
SD-card boot is supported via on-board bootloader (SPL) or recovery button.
|
|
|
|
## eMMC
|
|
|
|
eMMC boot is currently only supported via recovery button. eMMC boot via
|
|
on-board bootloader will require an update of Petitboot (as of March 13 2023,
|
|
this update hasn't been released yet.
|
|
|
|
## NVMe
|
|
|
|
Booting directly from NVMe is not supported. The NVMe card can be used as a data disk.
|
|
|
|
## Technical notes on boot flow
|
|
|
|
The Home Assistant OS image is bootable by the SoC directly. This means that no help
|
|
from the Hardkernel provided and pre-installed bootloader Petitboot is necessary.
|
|
However, the ODROID-M1 automatically boots from internal SPI. To boot
|
|
directly off the SD-card or eMMC you need to press the recovery button.
|
|
|
|
The SPI flashed U-Boot SPL tries searches for an U-Boot binary on the SD-card
|
|
(and future releases also on the eMMC). This mechanism allows you to boot the Home
|
|
Assistant OS U-Boot without pressing the recovery button.
|
|
|
|
## Console
|
|
|
|
By default, console access is available on the serial header (CON1) and on HDMI.
|
|
The serial console's baudrate is 1500000 by default.
|
|
|
|
The systemd startup messages will only appear on the serial console by default.
|
|
To show the messages on the HDMI console instead, add the console manually
|
|
to the `cmdline.txt` file on the boot partition (e.g. `console=tty0`).
