Why does Linux fail to boot on my Intel® Stratix® 10 SoC when I use the f2s_free_clock as the HPS reference clock? - Why does Linux fail to boot on my Intel® Stratix® 10 SoC when I use the f2s_free_clock as the HPS reference clock? 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 the socfpga-4.18 branch of your local git clone of https://github.com/altera-opensource/linux-socfpga, then rebuild your Linux Kernel. 0001-fix-f2s_free_clk-setting_1.patch The patch for this issue has been released to https://github.com/altera-opensource/linux-socfpga.
