Renesas 740 Family Manual De Usuario

5.2. Connecting the debugger

For this tutorial it is not necessary to provide an external power supply to the board. The power will be obtained from the USB port. Please

be aware that if you have too many devices connected to your USB port it may be shut down by Windows. If this happens remove some

devices and try again. Alternatively provide an external power source taking care to ensure the correct polarity and voltage.

The Quick Start Guide provided with the Renesas Starter Kit board gives detailed instructions on how to connect the E8a to the host

computer. The following assumes that the steps in the Quick Start Guide have been followed and the E8a drivers have been installed.

• Fit the LCD module to J8 on the Renesas Starter Kit ensuring that pin 1 on the module corresponds to the indication on the

Renesas Starter Kit PCB.

• Connect the E8a debugger to the USB port on your computer.

• Connect the E8a Debugger to the target hardware ensuring that it is plugged into the connector marked J6 which is nearest

the power connector.

• If supplying external power to the board this can be turned on now.
