YAFFS is a file system so you need to do this using file system calls. You
cannot do a binary copy fromflash.
You need to do something like this:
unsigned char *buffer;
int load_handle = yaffs_open("filename",O_RDONLY,0);
buffer = (unsigned char *) load_address;
while ((nread = yaffs_read(load_handle,buffer,4096)) > 0)
buffer += nread;
yaffs_close(load_handle);
