U-boot for Banana Pi

[TooMeeK Admin]

And that's where real problem comes :)
Over serial console - J11 connector - I have only view (read-only) access..
Different RX/TX pairs aren't giving any output.
So the only way for me is putting commands into boot.scr file.

echo "fatls mmc 0; fatload mmc 0 0x40200000 kernel; go 0x40200100" > 
boot.cmd
/usr/src/u-boot-sunxi/tools/mkimage -C none -A arm -T script -d boot.cmd 
boot.scr

Gives output:
