Why does Linux fail to boot on my Intel® Stratix® 10 SoC when I use the f2s_free_clock as the HPS reference clock?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in Linux-socfpga Kernel version 4.17  for Intel® Stratix®  10 SoC from https://github.com/altera-opensource/linux-socfpga.  The Linux Kernel may fail to boot if the HPS reference clock has been specified as the f2s_free_clk in the Hard Processor System Intel Stratix 10 FPGA IP in the Intel Quartus® Prime Pro Platform Designer. 

    Resolution

    A patch for the linux-socfpga 4.18 Kernel is available to resolve this issue.  Download and apply the patch below to your socfpga-4.18 branch of your local git clone of https://github.com/altera-opensource/linux-socfpga,  then re-build your Linux Kernel.
