I'm trying to simulte an SD card in ISIS but I don't seem to be getting any where  Cry
 I created an card image ust using notepad (not sure if this is the correct way) but all that happens is, It asks me to insert card so I click to close card then it just says opening file and sits there and does nothing else.
I found a 32mb image file from here tried that and it just reports file exists.
What is the best way to create a card image file. It works in real life but I really want to use ISIS (been lazy and easier  Grin)

Didn't ISIS have a MMC memory card example? Thought I have seen it in one of their examples. Isn't SD similar to MMC cards? Both can use SPI.

You need to use something like WinImage (http://www.winimage.com/winimage.htm) to make an empty SD card image; just a normal FAT16 image of whatever size you want to simulate. Call it something like 'sdcard.bin' and load it into the model. When you've finished simulating open it in WinImage to extract the files.
