sunxi: a53: add support for Olimex A64-Olinuxino eMMC
Specifications:
SoC: Allwinner A64 (1.2 GHz Quad-Core ARM Cortex-A53 64-bit)
RAM: 1GB or 2GB RAM DDR3L @ 672Mhz
Flash: 0/4/16GB eMMC flash memory for storage and boot
MicroSD card connector for cards up to 32GB
Debug: serial UART debug header with 0.1" pins
Wired connectivity: 10/100/1000Mbps GbE Ethernet
Wireless connectivity: on-board RTL8723BS 1T1R 802.11bgn WiFi and
Bluetooth 4.0 module with built-in antenna
(only available in the A64-OLinuXino-1G4GW)
Flashing instructions:
Standard sunxi SD card installation procedure - copy eMMC image to SD
card, insert in into SD card slot on the device and boot. You should see
something like following if the eMMC is detected correctly:
mmcblk2: mmc2:0001 P1XXXX 3.60 GiB
mmcblk2boot0: mmc2:0001 P1XXXX partition 1 16.0 MiB
mmcblk2boot1: mmc2:0001 P1XXXX partition 2 16.0 MiB
Then flash SD card eMMC image straight into the mmcblk2 device:
dd if=/mnt/openwrt...a64-olinuxino-emmc-squashfs-sdcard.img of=/dev/mmcblk2
It also possible to boot from boot0 partition[1]:
1. Compile U-Boot with CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x40
otherwise the U-Boot will get stuck in bootloop
2. Configure eMMC to boot from boot0 partition inside U-Boot:
mmc bootbus 1 1 0 0; mmc partconf 1 1 1 0
3. echo 0 > /sys/block/mmcblk2boot0/force_ro
4. Write U-Boot from offset 0 (not offset 8k as with SD card) into
boot0 partition
dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk2boot0
Known issues:
Wireless doesn't work properly via netifd.
