4.2.4. Recompiling the Linux Kernel Driver

Attention: If you download and install the Intel® FPGA SDK for OpenCL™ Standard Edition, the Cyclone V SoC Development Kit Reference Platform ( INTELFPGAOCLSDKROOT/board/c5soc) includes an SD card image (linux_sd_card_image.tgz) that contains the recompiled Linux kernel driver.
If you need to rebuild the Linux kernel driver, recompile the aclsoc Linux kernel driver to the exact version of the Linux kernel running on the SoC FPGA.
Important: You must recompile the aclsoc Linux kernel driver on your Linux development machine.
  1. Unpack the aocl-rte-<version>.arm32.tgz tarball to a temporary directory on your development machine by typing the tar -xvfz aocl-rte-<version>.arm32.tgz command.
  2. Navigate to the INTELFPGAOCLSDKROOT/board/c5soc/driver subdirectory of the unpacked aclrte-arm32 package.
  3. Perform the tasks outlined in the Compiling the Linux Kernel for Cyclone V SoC section of the Intel® FPGA SDK for OpenCL™ Cyclone V SoC Development Kit Reference Platform Porting Guide.
