[U-Boot] ARM: Running U-boot on Raspberry Pi Zero W

[Grigory Emelyanov]

Hi

We are trying to run U-Boot on the Raspberry Pi Zero W. But all our
attempts have
finished at rainbow screen. During our experiments we have been following
an
instructions from (with a different config file, configs/rpi_defconfig).

http://ltekieli.com/buildroot-with-raspberry-pi-u-boot/

Also we have tried a method from

http://www.embeddedforu.com/embedded-linux/raspberry-pi/how-to-compile-mainline-u-boot-for-raspberry-pi/

However we have got the same result in both cases. At the same time we
don't
have any problem with Raspbery Pi 3 (with a different config file
configs/rpi_3_32b_defconfig).

We are using buildroot 2017.05 which contains U-boot 2017.03.

Thanks in advance,
