WebFeb 16, 2024 · This is done by halting the CPU target by the debugger agent, either by running into a breakpoint instruction ( BKPT 0xAB for ARMv6-M or ARMv7-M) or by sending a supervisor call instruction ( SVC 0xAB or SVC 0x123456) depending on the target architecture or processor. This indicates to the host that the target is requesting a … WebProcessor Refers to the Cortex-M0+ processor, as supplied by ARM.

WebApr 18, 2024 · BKPT is not generated by the compiler from normal code. It is generated *explicitly* in the source code. Normally, the SDKs do this when handling some sort of exceptional condition such as an assertion failure. In my SDK, fsl_assert.c (which is called from an assertion failure in the code) has 2 locations where a BKPT is generated. WebIn the ARM debugger when a software breakpoint (BKPT) instruction is hit the CPU halts as expected with the PC at the BKPT instruction and cursor at that line. What would be more handy is if the single step button (green down arrow) stepped past the BKPT as though it were a NOP., and the run button similarly.
