qemu emulator for the mini2440

[LeshaK]

I have error then I run your ru-script
I made a little modification - add -nographic, and:

Code: Select all

may be error in: u-boot (size 0) ?

Yes sorry, the u-boot.bin needs to be moved into the mini2440/ subdirectory (with the script)

Otherwise -nographic works, I used it.

[LeshaK]

I moved, but:

Hmm try launching the script from the qemu directory:

./mini2440/mini2440_start.sh

Thats how I used it, I haven't tried anything else. Sorry thats the last thing I;m interested in, shell scripts You can fix the script and make it better if you like

(the code that loads u-boot.bin is in hw/mini2440.c, near the bottom)

[LeshaK]

Thanks,
everything - ok!

[buserror]

So you like it ? works for you ?

I created a Blog too, so I don't have to post here (private forum, waste of my time) http://bliterness.blogspot.com/

I also created a new google code page, you can join if you like ! http://code.google.com/p/mini2440/

It has a wiki, space for binaries etc etc...

This is probably a simple question but how do you create the mini2440_nand.bin and mini2440_sd.img. I only see the uImage when I build the kernel.

Thanks.

[buserror]

the new script /should/ create a nand file if not present (just a dd) it's a good idea to "nand scrub" it the first time, using u-boot.

the _sd file can be created with "qemu-img" ...
OR it can be any directory if you pass the argument like -sd fat:/some_directory

If you create the qemu-img, it will be empty, you will have to partition/populate it from inside a running qemu..

First of all I would like to thank you for the help as I'm a bit of a newbie. I am trying to boot via nfs root but am getting this:

also for the sd boot when you say it can be any directory if you pass the argument like -sd fat:/some_directory, what do you need the "some_directory" for it to work, just the basic linux fs?
