Please be sure to keep the linux-sunxi mailing list in CC (I have
added it back). I generally don't provide private personalized
support, unless it's a paid job.

If you have the mksunxiboot tool (which is one of the command
line tools from U-Boot), then the makefile should produce the
uart0-helloworld-sdboot.sunxi file. See more details at
https://linux-sunxi.org/BROM

Then you can write this uart0-helloworld-sdboot.sunxi file to the SD
card in the same way as you write the U-Boot bootloader. For example
the following commands will download and write a precompiled binary:

wget 
https://github.com/linux-sunxi/sunxi-tools/raw/master/bin/uart0-helloworld-sdboot.sunxi
dd if=uart0-helloworld-sdboot.sunxi of=/dev/sdX bs=1024 seek=8

Alternatively, you can load and execute this file to the device over
Mini- or Micro- USB cable (after switching the device into FEL mode):

sunxi-fel spl uart0-helloworld-sdboot.sunxi

Using FEL boot method is typically much more convenient for development
and debugging. Because you don't need to repeatedly insert/remove the
SD card between your device and your card reader.

I hope that this information can help you to get your secret operating
system up and running on your Cubietruck :-)

Hello,

You can check the uart0-helloworld-sdboot.c code from sunxi-tools:
https://github.com/linux-sunxi/sunxi-tools

I believe that it does exactly what you need. It uses the GPL
license though. So if your operating system is proprietary, then
you can't copy/paste this code directly.

If your operating system is open source, then I'm quite curious
to have a look at it.

[linux-sunxi] Bare metal example for cubietruck

[dlbp]

Hello!
I'm using a cubietruck and because i Need to port an operating system from x86 
to ARM architecture, i need an example of bare metal software for a Cubietruck 
(with Cortex A-7). It's good also a simple hello world bare metal.

It is very important!

Thanks in advance
