Web2. Software breakpoint instruction: Through BKPT instruction, an abort exception is generated. In the presence of debugger software, abort exception is treated as a breakpoint. While when there is debug hardware then abort exception does not occur and BKPT instruction is directly considered as a breakpoint. Applications of ARM Processor WebJun 23, 2015 · In Cortex A7 (an ARM v7a implementation from ARM) six hardware breakpoints are available. Checkout section: 10.2.2 (Breakpoints and Watchpoints) of the Cortext A7 TRM When you run out of hardware breakpoints, there is a BKPT instruction which the debugger inserts to halt execution.
