# Odroid-C2
## eMMC
eMMC support is provided transparently. Just flash the image to the eMMC board as you would an SD card.
## Console
By default, console access is granted over the serial header and over HDMI. Certain startup messages will only appear on the serial console by default. To show the messages on the HDMI console instead, swap the order of the two consoles in the `cmdline.txt` file on the boot partition. You can also delete the AML0 console if you don't plan on using the serial adapter.
eg. `console=ttyAML0,115200n8 console=tty0`
## USB
A long-standing kernel bug currently results in some odd behavior. To use the USB, a device must be plugged into one of the USB ports at hard boot. If all devices are removed from the USB ports, the USB will cease to function until a reboot.
### OTG
The OTG USB is untested.
## GPIO
Refer to [the odroid wiki](https://wiki.odroid.com/odroid-c2/hardware/expansion_connectors).

# Development
## Boot system
`BOOT_SYS`:
- efi
- hyprid
- spl
- mbr
HassOS is basicly used GPT. But for use GPT we need own the first 1024 of
boot drive. Is that not possible, you can use MBR for your device, they work also with SPLs.
Hyprid and SPL use both a hyprid MBR/GPT table but SPL move the GPT header 8MB for give space to write SPL and boot images before.
`BOOTLOADER`:
- uboot
- barebox
We support mainly uboot but for uefi system we can also use barebox. In future we hope to remove barebox with uboot also on uefi.
`DISK_SIZE`:
Default 2. That is the size of end image in GB.
