5.FAQ

1\) How to enable AP mode Please refer to link: <http://forum.banana-pi.org/t/2-4ghz-and-5-6ghz-wifi-working-fine/3844/32>

2\) How to enable BT Please use command: hciconfig hci0 up to enable it

3\) How to program Ubuntu image to EMMC

a. Program ubuntu image to SD card

b. Install this SD to R2 board and boot from SD

c. Enter the Uboot prompt, and run command emmc pconf 48 to change Partition config of EMMC

d. And then run command reset, let it boot to OS

e. Enter the system with username pi or root

f. Run command

`echo 0 > /sys/block/mmcblk1boot0/force_ro to enable /dev/mmcblk1boot0 write mode`

g.To write preloader to EMMC by running command:

`bpi-bootsel BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz /dev/mmcblk1boot0`

where BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz is the preloader for emmc, please download it from link <https://github.com/BPI-SINOVOIP/BPI-files/blob/master/SD/100MB/BPI-R2-EMMC-boot0-DDR1600-0k-0905.img.gz>

h. To copy ubuntu image to EMMC:

`unzip -p <XXX.img.zip> | pv | dd of=<device> bs=10M status=noxfer`
