TX is outbound traffic, isn't it?

You don't need the full FAT32 filesystem function, just reading.

No, the Arduino will use the SD card.  smiley-razz

I could, but that'd be extremely slow.

Yes, you can use a board as an ISP, which can then program another.

And would it be that hard to edit that code, for what the OP needs?

Gumstix looks awesome, I might use that instead.

You got no reason for insulting me.

No more offtopic, here's the link: http://www.roguerobotics.com/wikidocs/code/bootloader_using_ummc

And when you do understand more you will find that it is imposable.

Imposable?

Any way, I'm sure that I saw a bootloader that reads a HEX file from the microSD card and writes it to the flash memory.

I think that I phrased it wrong.

I got the Ethernet shield, which already has a microSD card reader.
I'll use it in my sketch. What I'm trying to do, is to add one more USB port, through which the computer can read the microSD card in the Arduino.

No, I'm expecting the Arduino to let me add another USB port, so that I can use it as a card reader too.

Yes, I know how big the file will be.
11  Using Arduino / Project Guidance / Re: 4MB of RAM? on: January 17, 2012, 10:52:03 am
No, the files will be used on a computer. Hence my other thread.

@florinc: that's a good idea!

The big string will be sent to the Arduino through Ethernet, and many pieces, when put together in a specific order, will form a file. Somewhat like BitTorrent, but different.
14  Using Arduino / Project Guidance / Re: 4MB of RAM? on: January 17, 2012, 08:54:28 am
Binary part, will later be added to a file.
15  Using Arduino / Project Guidance / Re: 4MB of RAM? on: January 17, 2012, 08:29:38 am
It will end up being stored on the SD anyway.

The string will come from the Internet.
