IAR Embedded Workbench for RISC-V 3.40

Interrupt Log window

In this section:

What do you want to do?

YellowStripe.png

The Interrupt Log window is available from the C-SPY driver menu.

InterruptLogWin_Mym80_06.png

This window logs entrances to and exits from interrupts. The C-SPY Simulator also logs internal state changes.

The information is useful for debugging the interrupt handling in the target system. When the Interrupt Log window is open, it is updated continuously at runtime.

Note

There is a limit on the number of saved logs. When this limit is exceeded, the oldest entries in the buffer are erased.

For more information, see Getting started using interrupt logging.

Requirements

The C-SPY simulator.

Display area

This area contains these columns:

Time

The time for the interrupt entrance, based on an internally specified clock frequency.

This column is available when you have selected Show Time from the context menu.

Cycles

The number of cycles from the start of the execution until the event.

This column is available when you have selected Show Cycles from the context menu.

Interrupt

The interrupt as defined in the device description file.

Status

Shows the event status of the interrupt:

Triggered, the interrupt has passed its activation time.

Forced, the same as Triggered, but the interrupt was forced from the Available Interrupts window.

Enter, the interrupt is currently executing.

Leave, the interrupt has been executed.

Expired, the interrupt hold time has expired without the interrupt being executed.

Rejected, the interrupt has been rejected because the necessary interrupt registers were not set up to accept the interrupt.

Program Counter

The value of the program counter when the event occurred.

Execution Time/Cycles

The time spent in the interrupt, calculated using the Enter and Leave timestamps. This includes time spent in any subroutines or other interrupts that occurred in the specific interrupt.

Context menu

This context menu is available:

InterruptLogWinPopUp_Mym80_03.png

These commands are available:

Enable

Enables the logging system. The system will log information also when the window is closed.

Clear

Deletes the log information. Note that this will also happen when you reset the debugger.

Save to File

Displays a standard file selection dialog box where you can select the destination file for the log information. The entries in the log file are separated by TAB and LF characters. An X in the Approx column indicates that the timestamp is an approximation.

Show Time

Displays the Time column. If the Time column is displayed by default in the C-SPY driver you are using, this menu command is not available.

Show Cycles

Displays the Cycles column. If the Cycles column is not supported in the C-SPY driver you are using, this menu command is not available.
