hello my friends!
I want to implement Atmel composite device code (msd+hid) on at91sam7s256. I downloaded the software package and tried to implement usb mass storage first, it worked correctly in IAR but when I use keil version of it computer recognize a removable device but can't format it.
1- why the keil version of usb mass storage does'nt work but IAR version , works correctly without any need to change code ? 2- Is there any configuration about keil that is need for this to set?
another problem is that *all of composite sample codes both in IAR and Keil doesn't work* what is the problem?
please help me!! thanks for your attention!!!!
I don't have AT91SAM7S256, so I can't check your problem directly. But by the experience on Ateml examples of another MCUs, Mass storage examples have two options of their media, on-chip code FLASH or external memory chips (or SD card). As the size of on-chip code FLASH is too small, Windows format command fails.

hello my friend! thank you for your reply to me! in fact I want to implement mass storage on external dataflash (at45db161d) so I tried to test sample code from Atmel that implements mass storage on internal flash, can you help me about this!
how I can replace internal flash with external at45 dataflash . Are there any examples for me ?
thenks!
