Segmentation Fault When Registering GPIO Interrupt Handler

Environment

  • Quartus® II Subscription Edition
  • Linux*

    BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    In the Linux implementation included with the Golden System Reference Design, if you attempt to register an interrupt handler for a nonexistent GPIO device, you will see error messages similar to the following:

    Unable to handle kernel NULL pointer dereference at virtual address 00000028 ... Segmentation fault

    These errors indicate a kernel segmentation fault.

    Resolution

    With the Golden System Reference Design, ensure that you attempt to register interrupts only for existing GPIO devices.

    Alternatively, upgrade to v13.1 or later.
