IAR Embedded Workbench for RISC-V 3.40

USB driver installation

In this section:

C-SPY needs a USB driver, which (for some probes) is automatically installed. If the USB driver is not installed automatically, you will need to install it manually.

Installing the I-jet USB driver

I-jet does not require any special driver software installation. Normally, all drivers for I-jet are automatically installed as part of the installation of IAR Embedded Workbench.

If you need to install the USB driver manually, navigate to \iar\ewriscv-x.x\riscv\drivers\ijet\USB\32-bit or 64-bit (depending on your system). Start the dpinst.exe application. This will install the USB driver. Note that the USB3 drivers are in the \riscv\drivers\ijet\USB3 directory.

Installing the I-jet Trace USB driver

I-jet Trace does not require any special driver software installation. Normally, all drivers for I-jet Trace are automatically installed as part of the installation of IAR Embedded Workbench.

If you need to install the USB driver manually, navigate to \riscv\drivers\jet\USB3\32-bit or 64-bit (in the installation directory). Start the dpinst.exe application. This will install the USB driver.

The USB LED will flash twice after enumerating on the USB2 ports, and three times on USB3 ports.
