sdk Returning Improper Sequence values in XSDK From HLS IP

[Thausikan]

Hi,Just start learning HLS and XSDk.  Currently I am working with number series. My goal is to print number series sequentially as for "N" times in Tera Terminal. While compiling the program codes, its returning values but it is not in sequence.

Expected result:2, 4, 8, 16,32,64,128,256,512,1024,

But i am getting : 4,8,16,256,128,1024,16,64,512,64, (not in order)

For more details refer this [link]: https://forums.xilinx.com/t5/Welcome-Join/Returning-only-Last-value-in-XSDK-From-HLS-IP-Instead-of-series/td-p/767236

void Numberseries1(ap_uint<32> seed, ap_uint<32> &dout)

{

#pragma HLS INTERFACE s_axilite port=seed bundle=a
#pragma HLS INTERFACE s_axilite port=dout bundle=a
#pragma HLS INTERFACE s_axilite port=return bundle=a
 ap_uint<32> reg[10];
    int result=1;

    int i;

    for(i=0;  i < 10;i++)

#pragma HLS unroll factor=8
        if (result<seed)
        {
            result *= 2;
            reg =result;
            dout= reg;

        }

}

Hi @Thausikan,

I am not very experienced with HLS. Had you tried to remove all but the initial #pragma. I do not see reg being set as a datatype?

thank you,
