Copy image from included micorsd card to a larger 8G card

[TroyCondit]

Hi all,

Just wanted to comment on how I copied the image from the 4g card to a new larger 8g card.

First let you know I'm a windows guy and new to linux, so the posts that show how to do it with the command line and LBIT were a little scary looking.

I used VMplayer and used two usb to SD card readers using a terminal issued a dd command.

That worked and the board boots just fine.

My goal is to get Apache up and running ( im new to this as well)

and create a server that will display data that is received  over the QSB serial port, any hints would be apriciated.

What I need to do now is the dd command created a 4g partition and left the other 4g alone. I need to figure out how to merge them into one so installs will be easier.

Then isntall and set up a web server.

and last figure out how to take control of the Serial port, I will be using C++ but need to know how to disable its use by u-boot.

Thanks Troy

Thanks for the help guys,  I will check out those resources.  I know I have a lot to learn.

I will keep posting updates and share what i've learned along the way.

BTW got tomcat6 installed, it might be better suited for my needs.

The slides for the i.MX53 hands-on training might be interesting as an introduction. You can get the slides here on iMXCommunity: http://imxcommunity.org/group/imx53quickstartboard/forum/topics/imx53-quick-start-board-1?xg_source=...

- They are more or less similar.
  U-BOOT, as the name imply, is primarily a boot loader, with
  some peripherals configuration capabilities; while the BIOS
  is primarily a collection of basic I/O functions, with
  peripherals configuration.

- "rootfs" can be seen as a container that hold system configurations
  and GNU applications.
  Using Ltib, you can customize rootfs by adding/removing GNU
  applications.  You can also add your own applications.

Claude,

Thanks you for that,  didn't know U-boot needs the port, that may be a problem for me,  I will read that doc.

Is U-boot similar a PC BIOS?,  how does rootfs fit into the picture?

Thanks,

Troy

- To partition the SD-Card, use "fdisk", not "dd".

- "U-BOOT" need the serial port to work.
  However, once the i.MX53 QSB is running under GNU/Linux,
  "U-BOOT" is no longer running, and it is GNU/Linux that
  have control of the serial port.  Probably, using "getty".
  So, it is possible to make the serial port available for
  user application, by avoiding GNU/Linux to launch
  "getty" on the serial port.  It is just a matter of
  some configuration change.


- I suggest you to take some basic training before getting
  in depth in your project.  That way, you will learn
  all the basic stuff you need to get the work done.
  Take a look at i.MX53 QSB BSP documentation.  There is a lot
  to learn, just reading that documentation.
  ... Because working with GNU/Linux on embedded system is really
  not obvious.


Regard,
Claude
