FriendlyCore System Cross-Compiler
- it applies to 64-bit Armv8 Cortex-A, little-endian architechture. FriendlyElec uses it for its H5 based boards.
- It can recognize a FriendlyElec's H5 based board and load its dtb file accordingly.
- It optimizes memory settings.
- It supports voltage regulation IC sy8106a and applies only to NanoPi K1 Plus/NanoPi NEO Core2.
- It supports MAC generation from H5's CPU ID.
- It supports system booting from either SD card or eMMC and can automatically load the kernel from the booting device.
- It supports LED. You can access it via "/sys/class/leds".
- It supports GPIO. You can access it via "/sys/class/gpio/".
- It supports UART0/1/2/3. You can access it via "/dev/ttySX".
