// Clone BPI-M3-bsp //
Edit the file sys_config.fex
/BPI-M3-bsp/sunxi-pack/chips/sun8iw6p1/configs/BPI_M3_1080P/sys_config.fex
I use HDMI-1080P, for other Resolution or Video Output must chage the path /BPI_M3_1080P/
Edit sys_config.fex: aud look for [mmc0_para]

; sdc_used: 1-enable card, 0-disable card |
; sdc_detmode: card detect mode |
; 1-detect card by gpio polling |

; sdc_regulator: power control.if card supports UHS-I/DDR and HS200 timing for|
; SD3.0 or eMMC4.5, regulator must be configured. the value is |

; else if detmode=1, sdc_det's config=0 |
; else sdc_det IO is not necessary |
; 2 if the customer wants to support UHS-I and HS200 features, he must provide|
; an independent power supply for the card. This is only used in platforms |
; that supports SD3.0 cards and eMMC4.4+ flashes |

And the most important!
Change sdc_detmode from 3 to 1
After compile (BPI-M3-bsp) boot from SD Card, flash eMMC with the 5 files ,
I think I order the NanoPi M3 . I found a lot of interesting properties . Actually , GPIO is compatible with all other boards (40pin banana, raspi, orange...) . But , there is something interesting to read : http://wiki.friendlyarm.com/wiki/images/8/8b/SEC_S5P6818X_Users_Manual_preliminary_Ver_0.00.pdf
SPDIF - TX and RX, LVDS, HDMI and MIPI, ADC (!) & more.... and, and, and...
And 45 bucks (with shipping) are 40 Yuros That I can still afford ( for fun )
The T3 would be better, but it costs more than twice M3
And ... this is completely different than the 'banana' or 'orange' (at least for me)
Great
