  • UART is accessible on pin 6 (GND),8 (TX) and 10 (RX) and with unusual speed: 1500000
  • flash the 128M SPI memory to also boot from USB or PXE (it if goes wrong, follow these instructions)
  • short-pressing (~1s) the power button turns the board on, long-pressing it (~3s) turns it off. If it gets stuck while halting, press the reset button. If it does not boot (ie the white led does not come up), reset, then power on.
  • if you experience USB3 storage lack of reliability (error messages followed by filesystem corruption), check your power supply, usb cable and connectors and disk/ssd. All these factors can lead to undervoltage issues (some ssd could produce power consumption spikes triggering undervoltage).

Odroid XU4 / HCx

For HC1 and HC2 we provide specially optimized config which you can enable via armbian-config -> system -> kernel -> select odroid configuration. This results in shorter boot time and lower consumption. Manualls – edit or create /boot/armbianEnv.txt and add: board_name=xu4 # or xu3, xu3, hc1

Overlay management via armbian-config is not supported. You need to edit /boot/boot.ini and add overlays manually. Look for a line:
setenv overlays "i2c0 i2c1 hktft-cs-ogst"

Here you add what you need. More you can find in /boot/dtb/ or /boot/dtb/overlays

Make sure to adjust path in

ext4load mmc 0:1 0x60000000 /boot/dtb/overlays/${overlay}.dtbo

accordingly.
