IAR Embedded Workbench for Arm 9.70.x

Vector Catch dialog box

In this section:

The Vector Catch dialog box is available from the C-SPY driver menu.

VectorCatchCM3_01_ARM.png

Use this dialog box to set a breakpoint directly on a vector in the interrupt vector table, without using a hardware breakpoint. You can set breakpoints on vectors for Arm9/10/11 and all Cortex devices.

Note that the settings you make here will not be preserved between debug sessions.

This figure reflects a Cortex-M device. If you are using another device, the contents of this dialog box might look different.

Note

For the C-SPY I-jet driver and the C-SPY J-Link/J-Trace driver, it is also possible to set breakpoints directly on a vector already in the options dialog box, see J-Link/J-Trace — Setup.

Requirements

One of these alternatives:

  • The C-SPY I-jet driver

  • The C-SPY J-Link/J-Trace driver

  • The C-SPY CMSIS-DAP driver
