    Can it be that you are really allergic to bananas? Imagine that quite a lot of people eat the bananas - even the light brown

    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]

    After compile (BPI-M3-bsp)  boot from SD Card, flash eMMC with the  5 files ,
     
    export card=/dev/mmcblk1
     
    dd if=boot0_sdcard.fex of=${card} bs=1k seek=8
    dd if=u-boot.fex of=${card} bs=1k seek=19096
    dd if=sunxi_mbr.fex of=${card} bs=1k seek=20480
    dd if=boot-resource.fex of=${card} bs=1k seek=36864
    dd if=env.fex of=${card} bs=1k seek=69632
    dd if=boot.fex of=${card} bs=1k seek=86016
     
    Shutdown -h now, SD card out, boot fom eMMC, plug the SD inside and.....   Problem solved!  
     
    Great

    eternalWalker got a reaction from wildcat_paris in [NanoPi M3] Cheap 8 core (35$)   
    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
