TMS320F28388D: How to avoid structure padding in C2000

Hi Team,

I am using TMS320F28388 controller with CCS 11.

While writing the program I have to use a structure like below.

struct HostReply
{
uint16_t Length;
uint32_t BoardStatus;
uint32_t SignalStatus;
union
{
uint16_t Data; // for Read, CRC16 for Write
uint16_t CRC16; // so that sizeof(HostReply) = sizeof(Length) + sizeof(BoardStatus) + sizeof(CRC16)
} Data_CRC;
};

But when I copy the structure data to a buffer, the Length variable is added with extra 2bytes of data. I understood this is structure padding and tried to avoid that using #pragma packet(1) header.

But got a warning like #163-D unrecognized #pragma.

Can you help me to fix this issue and pack the structure properly.

Thanks in advance
