3.4 Launching the OPT300x/4xxxEVM Software

With the OPTEVM properly connected, launch the Latte OPTEVM GUI software from the Windows Start menu. The software launches with a screen similar to that shown in Figure 3-11. The exact GUI screen varies based on the EVM variant. This section describes the following devices.

If the message shown in Figure 3-12 appears when the OPTEVM GUI software is launched, then this means that the OPTMB EVM board was not detected. The device name varies according to the OPTEVM selected. Check the USB connection and that the OPTMB EVM board appears in the device manager as shown. A green light appears on the motherboard if the motherboard is receiving power from the PC and the GUI Start Capture button has not been clicked.
