Hello,
I'm developing a "USB card reader" which must read a 512 bytes non-writable memory and display it as a file.
Since the 512 bytes memory contains only data which have to be stored in the file, I have to define in firmware the entire FAT as a big array. Thus, no possibility to format the media using for example Windows.
I'm encountering problems when I connect my device to the host PC: Windows
7 asks if I want to format the removable device. As I understood and as I saw with my USB analyzer, the OS doesn't seem to understand the FAT boot sector. I based on the USB Mass Storage book from Jan Axelson.Do someone have some ideas about what fields in the boot sector can generate such an error? Do you know where I can find some documentation on how Windows set the boot sector?
Thank you, Johann
