There are no complete examples because that would require a lot of code
beyond the scope of yaffs.
There are many places you could have gone wrong. Did you set up the device
correctly? Do you have errors in the driver? Whenever you get an error
return there is an error code available via:
int yaffs_get_error(void);
const char *yaffs_error_to_str(int err);
Also, for getting going it is worth setting the yaffs_trace_mask to get
more info.
