how works a bootloader(sd) image (SD > 64MB)

[Mattezh]

Hi all !

My Question ist, how the bootloader saves the image, if the used card is bigger than the rom? The image doesn't seam to be empty after the first 64Mbytes....

anybody knows something?

The non-emptiness after 64MB is just the garbage what was present before dumping your rom.

You can check it by writing a specific pattern to your SD & then dump your rom.

But, thanks for answering! I'm sure you wasn't the only one who knows this!

Probably most readers had a 'well that's obvious dude' experience.
I found out that some people on the board are really inexperienced with any kind of computers & can be helped with a small explanation.

Unfortunately not. You can dump your rom on a SD-Card & save that to your hard-disk or what-ever. The magician won't boot from your SD in a way that you can free up your internal rom-memory. Man I wish it would.
You can supply a new rom to your magician in two ways: the first is with active sync and the second is via a rom-image on a sd-card. The bootloader will recognize the rom-image on the sd & start flashing it into it's internal rom memory.

So Mattezh question was about dumping his internal rom on a sd-card. If you do this & save the rom image on your PC the program to read the image from your sd will not know where the rom image ends. So it just copy every bit from your sd to your PC & that's why there's a lot of garbage in the saved image after the 64MB size of the image.

Understandable? I hope cause I know I sometimes tend to write a bit weird, I know :-)
