Right. So for your ARM FP library, the code goes from
case 6: /* 8-byte signed integer */
case 7: { /* IEEE floating point */
u64 x = (buf[0]<<24) | (buf[1]<<16) | (buf[2]<<8) | buf[3];
u32 y = (buf[4]<<24) | (buf[5]<<16) | (buf[6]<<8) | buf[7];
x = (x<<32) | y;
if( serial_type==6 ){
pMem->i = *(i64*)&x;
pMem->flags = MEM_Int;
}else{
pMem->r = *(double*)&x;
pMem->flags = MEM_Real;
}
to
case 6: /* 8-byte signed integer */
u64 x = (buf[0]<<24) | (buf[1]<<16) | (buf[2]<<8) | buf[3];
u32 y = (buf[4]<<24) | (buf[5]<<16) | (buf[6]<<8) | buf[7];
x = (x<<32) | y;
pMem->i = *(i64*)&x;
pMem->flags = MEM_Int;
break;
case 7: { /* IEEE floating point */
u64 x = (buf[0]<<24) | (buf[1]<<16) | (buf[2]<<8) | buf[3];
u32 y = (buf[4]<<24) | (buf[5]<<16) | (buf[6]<<8) | buf[7];
x = (y<<32) | x;
pMem->r = *(double*)&x;
pMem->flags = MEM_Real;
