Ivthandleinterrupt

In some cases, the error is triggered by physical hardware issues:

An Interrupt Vector Table (IVT) is an array of memory pointers located at a fixed address in physical memory. Each entry in the table, known as an , stores the absolute or segmented address of an Interrupt Service Routine (ISR) —the specialized function written to process a particular event. ivthandleinterrupt

Defining the IVTHandleInterrupt function is not enough. You must register it in the IVT so the CPU knows where to find it. In some cases, the error is triggered by

Contrary to what the error text implies, for this crash to occur. Windows natively utilizes the underlying driver validation ruleset to enforce Kernel DMA Protection . Why the Crash Occurs You must register it in the IVT so

NVIC->ICPR[0] = (1 << irq_num); // clear pending
