Why my bitstream bring errors

I'm trying to use intel sdk for OpenCL 20.3 to program de10_pro. But when I program a bitstream, the diagnose failed when reading or writing fpga.

The error message is as follow:

FAILED to read auto-discovery string at byte 61. Full auto-discovery string value is 20 20 81d369d2b25191e24199d2e694189ed48a41e80d s11_sh2e1_8Gx2 0 1 13 DDR 0 2 24 1 2 0 858x934592 8589934582 17179969184 0 - 0 0 0 1 97 mi(imap2_o0encl0 0`256 1 0 0 1 0 1 0 10 6 1 0 8 1 0 0 6 0 0 4 1 0 0 6 0 0 0 1 0 0 p 0 0 4 0 0 0 6 0 0 4 1 1 0 6 0 0 4 1 0 0 6 2 1 8 1024 0 3 6 2 1`8 1024 0 2 6 2 0 8 1024!0 2 6 2 1 8 1020 0 3 0 0 1 2 64 0 1 1 1`3 1 1 1 3 1 0

The command I used to generate bitstream is:

aoc -fmax 100 -v -report device/$FILE.cl -o bin/$FILE.aocx -hyper-optimized-handshaking=off

Any suggestion why this bitstream get wrong?

    Hi @myg,


    Thank you for posting in Intel community forum, hope all is well and apologies for the delayed in response.

    Could you further share which references design you are going through. With those information it would be a great help for us to understand the situation better.


    To understand the situation better, you have successfully generated the bitstream with the mention command however the error mention occurs during the programming of the bitstream?

    Hope to hear from you soon.
