IAR Debug Probes

Updating the probe firmware

In this section:

I-jet and I-jet Trace are designed so that firmware updates are not necessary unless new features added to IAR Embedded Workbench require extra hardware support. When a new version of IAR Embedded Workbench is released and a new feature that requires new firmware is used, C-SPY displays a message in the Debug Log window asking you to update the firmware.

Note

Support for new MCU devices is managed by software updates in IAR Embedded Workbench, and has nothing to do with I-jet or I-jet Trace firmware.

For more information about firmware versions, see the release notes.

Warning

Make sure that you do not accidentally disconnect the probe during the update process, as this can damage the probe permanently.

To update the probe firmware:

  1. In IAR Embedded Workbench, choose I-jet>EmuDiag to display the About to Connect to an Emulator dialog box.

    IAR Embedded Workbench for RISC-V: riscv\bin\ijet\firmware\i-jet

    In one of the subfolders, select the firmware file that you want to use and click Open.
