Is there analogue of #pragma PACK for the C6000 compiler?

Depends. From what I have seen, older C6000 compilers in CCS3/CGT6 do not support packed structures at all. The newer CCS5/CGT7 compiler supports packed via GCC style "__attribute__ ((packed))" specifiers. You must have GCC extensions enabled during the compile.

Thank you very much for the suggestion. But I can't do what I want even when I use that directive.

I try to declare a structure:

__attribute__((__packed__))
typedef struct
{
	T_IP_ID id;
	T_IP_TYPE type;
	uint16_t len;	
	uint8_t payload[INTERPROC_BUF_SIZE];
} T_INTERPROC_CMD;

but I've got a warning message:

#1176-D the "packed" attribute is ignored in a typedef

I don't have an idea how to fix that because I need to cast a pointer from a raw byte array to the structure like that:

uint8_t byte_array[100500];
T_INTERPROC_CMD *p_buf = (T_INTERPROC_CMD *)byte_array;

P.S. My version of CCS is 6.0.1.00040, processor is C6748 (OMAP-L138 DSP core)

It works fine, thank you very much!
