Hi All,
I had ordered the A13 board without Nand and Wifi but when i got it i wanted to check the hardware did something before i started changing things.
It took me a long time to work out how to create a micro SD card that would do anything with the hardware so i thought id share how i did it eventually.

This post here, has a link to a 2g uSD card image
https://www.olimex.com/forum/index.php?topic=7.msg226#msg226

File location: http://31.13.212.1/debian_2g.tar.bz2

as suggested in the post download the file,
unzip the file using #tar jxf debian_2g.tar.bz2
this gives an image file

place it onto the SD card using
dd if=debian_2g.img of=/dev/sdX, where X is you uSD card.

it appears this works without setting up uboot or building a kernal.
However the only thing it did for me was start the VGA output and allow log in using
user: root
pass: password

and why do you use this old image instead the one in the WIKI?

I didn't use the one on the wiki because there weren't instructions on how to put it onto the SD card. I was assuming i couldn't just click and drag it in ubuntu.
the script bin and fex tool confused me as well since i dont use linux very much and im only getting started with the A13

I had assumed it was an image that had to be copied on using partitions and uboot and scripts which i dont yet understand.

if this is a file that can just be copied to a blank SD card can i recommend the wiki be updated with some minimal instructions on how to do that.

You can 'flash' the debian sd card image posted on the wiki with dd ( as you did for the previous image )
The default script.bin enables vga output, so you have to connect the board to a vga monitor and you are ok to start...
