and I do the same changes to "static const uint16_t crc16_tab[] =" ?

yes, all uint16_t needs to be replaced with unsigned short int.

static const cyg_uint16 crc16_tab[] = {

shall I change cyg_unit16 to unsigned short int too?

yes, change it to unsigned short. and any other variation on uint16 you find is also unsigned short.

parse error before "crc16_tab"

That is not the complete error. And I can't see your code from here.

Please don't take this to PM's, I'm supposed to help you here so the solution can help everyone with this problem.

Seeing the code, you still need to change "static const cyg_unsigned" to "static const unsigned short".

thanks, that solved the problem of uint16, but I'm still not sure how to pass my structure to CRC

e.g.

typedef struct header
{

unsigned short s;
unsigned short d;
unsigned int sq;
unsigned int a;
char hdr;
char rs;
char flg;
unsigned short w;
unsigned short cksum;


} header;


typedef struct Message {
struct header hdr;
char data[1024];
}Message;

=================

I need to pass these parameters and find the total CRC then save it in cksum,
no syntax error for my code but I'm getting a segmentation error!
