Odroid M1

Important: For Armbian 23.08 or more recent versions:

  1. Write image to SD using BalenaEtcher.
  2. Boot from SD by holding the recovery (RCI) button while powering the board.
  3. Release RCY button after the blue LED flashes once.
  4. Once booted, use armbian-install to write u-boot to MTD (SPI flash). This completely and irrevocably removes Petitboot, replacing it with mainline u-boot.
  5. You can also install to NVMe, USB, or eMMC. NVMe or eMMC is recommended.

For Armbian 23.05 and previous releases:

In order to boot Armbian, you need to disable Petitboot by running fw_setenv skip_spiboot true in the command line of Petitboot. This won’t run Petitboot again. But cons it will only boot from eMMC or SD card, not from USB nor NMVe nor SATA.
(this method no longer works for 23.08 or later, see above)

Odroid HC4

If you have variant with LCD display – here you can download driver.

Important: To be able to boot clean Armbian mainline based u-boot / kernel experiences, you need to remove incompatible Petitboot loader that is shipped with the board.

Try one of the following methods:

Bootloader Bypass Method

This is now the preferred method.  It is easier, and be performed without a display via SSH

    1. Install an SD Card with a fresh Armbian image
    2. Flip device upside down
    3. With a tool, press and hold down the black button.
    4. Continue holding button and plug in power to device
    5. Login to console or SSH and perform follow normal setup procedures
    6. Verify system can access SPI FLASH device and Erase
    7. Reboot
odroidhc4:~:# ls -ltr /dev/mtd*
crw------- 1 root root 90, 0 Nov  6 21:38 /dev/mtd0
brw-rw---- 1 root disk 31, 0 Nov  6 21:38 /dev/mtdblock0
crw------- 1 root root 90, 1 Nov  6 21:38 /dev/mtd0ro
odroidhc4:~:# flash_erase /dev/mtd0 0 0
Erasing 4 Kibyte @ fff000 -- 100 % complete
odroidhc4:~:#

 

Petitboot Console Method

Attach the device to a display and keyboard.  Power on.  Petitboot will load

From the Petitboot menu, go for “Exit to shell” and these commands to remove the Petitboot:

# flash_eraseall /dev/mtd0
# flash_eraseall /dev/mtd1
# flash_eraseall /dev/mtd2
# flash_eraseall /dev/mtd3

This will make your SPI flash memory empty and would start from SD on next boot.

In case you want to put Petitboot back to the board, user those instructions.

FAN support

Create a file in /etc/fancontrol with the following content:

INTERVAL=10
DEVPATH=hwmon0=devices/virtual/thermal/thermal_zone0 hwmon2=devices/platform/pwm-fan
DEVNAME=hwmon0=cpu_thermal hwmon2=pwmfan
FCTEMPS=hwmon2/pwm1=hwmon0/temp1_input
FCFANS= hwmon2/pwm1=hwmon2/fan1_input
MINTEMP=hwmon2/pwm1=50
MAXTEMP=hwmon2/pwm1=60
MINSTART=hwmon2/pwm1=20
MINSTOP=hwmon2/pwm1=28
MINPWM=hwmon2/pwm1=0
MAXPWM=hwmon2/pwm1=255

followed by:

sudo systemctl restart fancontrol

With kernel 5.15.y -> you need to remove FCFANS=hwmon2/pwm1=hwmon2/fan1_input in /etc/fancontrol

Odroid C4

In case you are experiencing reboot troubles, make sure to update u-boot. How? Run this command as root:

nand-sata-install -> "Update bootloader"

Odroid N2 / N2+

  • some people are having troubles with booting with Petitboot loader. In case you have troubles too, you need to disable Petitboot by running fw_setenv skip_spiboot true in the command line of Petitboot
  • On modern kernels adding “video=HDMI-A-1:1920x1080M@60D” to boot /boot/armbianEnv.txt (extraargs=) should force HDMI to 1080p instead of the 4K native resolution.

Odroid XU4 / HCx

For HC1 and HC2 we provide specially optimized config (for kernel 4.14.y or higher) which has to be applied manually. This results in shorter boot time and lower consumption. Run armbian-config utility and go to section system -> DTB and select optimized board configuration for Odroid HC1. The same config is valid for HC2 and MC1.
