On ARM Cortex M chips, there's a table of function pointers at a preset memory address. The table may be constructed in C or assembly, and if your interrupt handlers aren't exported with the correct name, the linker won't be able to find the addresses that belong in the table.

Commit 3efcdff3 [3] adds two code examples with a simplified kernel loop. SYMPTOM: Cortex-M3 and Cortex-M4 interrupts appear to be triggering twice. CAUSE: This may happen with devices: That add an external, system-level write buffer in their Cortex-M3 or Cortex-M4 design, AND The ISR code exits immediately after a write to clear the interrupt. The ARM Cortex Microcontroller Software Interface Standard (CMSIS) hardware abstraction layer for the ARM Cortex processor series is implemented and available for the M4 CPU. Real-time execution is highly deterministic in thread mode, to and from sleep modes, and when handling events at configurable priority levels via the Nested Vectored Interrupt Controller (NVIC). Interrupt using Cortex m4-This blog post explains interrupt programming with nxp lpc4088 cortex m4 development board.It contains c source code 2020-05-04 · It is functionally a subset of Cortex M3 and runs ARM v6 instruction set with OS extension options.
