Packed attribute working on TMS470 4.7.1 but not in 4.9.1

The packed attribute is still supported in compiler 4.9.x. Could you please post the full set of compile options used, as well as the complete error message output by the compiler? If possible, could you also attach the source file that generates the error so we can reproduce it? A preprocessed version of the source file would be best as it would pull in all the necessary includes.

Hello Aarti...Thx for the prompt reply.
