It can be frustrating when a Cortex-M0+ processor seems to hang or freeze during operation. One common situation where this occurs is when the processor hangs on return from a function call. There are several potential reasons why a Cortex-M0+ may hang on return, along with some steps you can take to debug and resolve

Yes, it is possible to copy the vector table from flash to SRAM, remap the SRAM to address 0x0, and have interrupts fetch vector addresses from SRAM instead of flash. This can provide performance benefits by reducing flash access latency during interrupt handling. The key steps are: Overview of Vector Table and Interrupts On ARM

The short answer is no, the Cortex-M0 does not always default the program counter to 0x0 when an interrupt triggers. The actual default address depends on the specific interrupt triggered and how the interrupts are configured. Overview of Cortex-M0 Interrupts The Cortex-M0 processor has several different kinds of interrupts that can be triggered by external

Debugging an embedded system running on a Cortex M0 processor implemented in an FPGA can be challenging but is an essential step in developing robust and reliable devices. This guide will walk through the basic steps needed to set up and use a debugger with a Cortex M0 soft core processor on an FPGA development
