If the application program uses IRQ interrupts, modify it to chain its IRQ handler to the Angel debugging monitor counterpart with a procedure similar to the following.
  • Page 88 Chapter 5 Notes on Debugging application program's handler. unsigned Install_Handler (unsigned *location, unsigned address) unsigned vec, oldvec; oldvec = *location; *location = address; return (oldvec); The return value provides the IRQ handler entry address before calling this function. Near the beginning of the main() function, place the following code for installing the application program's IRQ handler.
  • Page 89 Chapter 5 Notes on Debugging 4. Note the following with regard to SWI instructions. * Do not use SWI 0x123456 or SWI 0xab. The Angel debugging monitor uses these SWIs to support C library semihosting requests. * The application must restore registers to their states before the SWI instruction. * If the application program uses SWI instructions, modify it to chain its SWI handler to the Angel debugging monitor's SWI handler.
