Hardware installation
In this section:
USB drivers are automatically installed during the installation of IAR Embedded Workbench. If you need to re-install them, they are available both on the installation CD and in the rx\drivers\JLink\ directory in the installation directory. For more information about the hardware installation, see the documentation supplied with the J-Link debug probe.
The following power-up sequence is recommended to ensure proper communication between the target board, debug probe, and C-SPY:
Power up the target board.
Power up the J-Link debug probe.
Start the C-SPY debugging session.
