Hi
Yes ,I have tried ,and got the same informations.
I think,the u-boot couldn't load the boot.
But I am unfamiliar with the buildroot program.
I will try to fix when I am free.

@isle buildroot... https://github.com/buildroot/buildroot :-)

git checkout 2016.05

Hi
I have tested it again ,and the result is success.
the reason is load the wrong uboot ,we need clean up the spl and uboot from the EMMC FLASH
First of all flash a normal ubuntu firmware to the board ,then,boot the os.
clean the spl and uboot by

dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=4

Copy the code

then reboot ,
now,insert your sdcard and power up .

switch to partitions #0, OK
mmc0 is current device
