CoreELEC Odroid C2

Odroid C2. Quad core and 2Gb of RAM.

Good Stuff:

S905 ARM-64bit 1.5GHz Quad-core
2GB RAM
Gigabit-Ethernet
Supports H.264 and H.265 HEVC
Onboard IR receiver

Bad Stuff:

Poor choice of cases

The standard case is not great. But it does allow access to SD card and IR. Raspberry Pi2 cases will fit the Odroid C2, but block the SD card and IR.

Third party case made of high-grade powder-coated steel.

Update kernel config file on 9.2.0 for Odroid C2 to enable encryption edit the following file:

./projects/Amlogic/linux/linux.aarch64.conf

I added the following lines:

CONFIG_CRYPTO_LRW=m
CONFIG_CRYPTO_PCBC=m
CONFIG_CRYPTO_XTS=y
CONFIG_MD=y
CONFIG_DM_BUFIO=m
CONFIG_DM_BIO_PRISON=m
CONFIG_DM_PERSISTENT_DATA=m
CONFIG_DM_CRYPT=m
CONFIG_DM_SNAPSHOT=m
CONFIG_DM_THIN_PROVISIONING=m
CONFIG_DM_MIRROR=m
CONFIG_DM_RAID=m
CONFIG_BLK_DEV_DM_BUILTIN=y
CONFIG_BLK_DEV_DM=y
CONFIG_MD=y
CONFIG_DM_LOG_WRITES=m
CONFIG_DM_VERITY_AVB=m

Then:

PROJECT=Amlogic ./scripts/clean linux
PROJECT=Amlogic ./scripts/build linux

And finally

PROJECT=Amlogic make image

All 8 cores on the case. Took an hour or so to fully compile.

Images:

./target
