Error (18212): Cannot load final snapshot for partition "root_partition”

Environment

  • Intel® Quartus® Prime Pro Edition
  • Intel® FPGA SDK for OpenCL™ Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    Due to a problem in Intel® FPGA SDK for OpenCL™ version 19.1, you may see an OpenCL™ kernel compile crash after installing the Intel® Quartus® Prime Software 19.1 0.03 patch. The Intel® FPGA SDK for OpenCL™ uses BAK-cache (a local copy in a temporary folder of the local machine) to speed up subsequent kernel compiles.

    The error messages are shown below. It should be visible on the standard output and printed in quartus_sh_compile.log. 

     

    Error (18212): Cannot load final snapshot for partition "root_partition" - the partition is not in a version compatible format.

    Error: Quartus Prime MIF/HEX Update was unsuccessful. 1 error, 0 warnings

    Error (23035): Tcl error:

    Error (23031): Evaluation of Tcl script scripts/post_flow_pr.tcl unsuccessful

    Resolution

    There are two ways to work around this problem

    Approach 1 (Recommended)

    • Delete your local BAK cache. The problem will be solved for the next and all compiles onwards.
    • For Windows, remove $ENV{'USERPROFILE'}\\AppData\\Local\\aocl 
    • For Linux, remove /var/tmp/aocl/$ENV{USERNAME}

    Approach 2

    • Run “aoc” argument with this option “-no-read-bsp-bak-cache”. Note this will slow down compile by an hour
    • aoc -no-read-bsp-bak-cache <kernel>


    This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 19.3.
