Message Unable to generate code for requested granularity Description The compiler has generated a call a routine that performs longword operations on some data that is requested to be accessed with byte granularity. Because of this, the requested granularity will not be met for this data access. This routine may be generated for a memory copy routine (such as memcpy). The call can also be generated for certain struct assignments. User Action If the data must be accessed with byte granularity then write your own routine that does the required action using byte objects. If byte granularity is not needed at this point, the message can be ignored.
