Is this being fixed?

Depending on particular toolchain default ABI just because somebody
decided to frob compiler options is kind of stupid.

[linux-sunxi] armhf floating-point ABI mismatch causing build error

I also encountered this error when trying to build mainline u-boot on
Debian Jessie armhf.  I got it to build by adding -mfloat-abi=hard to
KBUILD_CFLAGS in the main Makefile, and the resulting u-boot seems to
work fine, but I don't know if there are any downsides to this approach.

Best wishes,
B.R. Oake.

[Piotr Kopeć]

I had some problems with the card so I created a small tutorial.
Tutorial Kurio 7S 
P.S. My mistake script.bin standard errors of the android is how you want to 
use
