Setup Guide
Running the µClinux Demo on the RSK
This chapter details the operation of the µClinux that has just been downloaded.
It is assumed that you have the following;
• RSK2+SH7670 development board & supplied PSU.
• A network connection to a PC (either direct using the supplied crossover cable or via an Ethernet hub)
• Renesas USB 128MB Stick k
Optional (not supplied) Optional (not supplied)
• Serial 9-way cable (for terminal connectivity to the SH device). • Serial 9-way cable (for terminal connectivity to the SH device).
Connecting the RSK Connecting the RSK
Insert the power connector into the board, plug the power supply into a mains socket and switch on the power at the mains
socket.

Board Setup Board Setup
In case the board configuration switches have been altered, the correct settings for this demonstration are: In case the board configuration switches have been altered, the correct settings for this demonstration are:
Switch Switch 1 1 10 10
SW4 1011111100
SW5 0101010101
SW6 0101011010
SW7 0110101010
Settings: 1=ON, 0=OFF in order 1-10 according to the legend on the switches.
Debugging / Terminal Output
You can connect the board to a development machine with a serial terminal emulator (e.g. Hyperterminal).
Set the port configuration details to 57600 baud, no parity, 8 data bits, 1 stop bit and no flow control (57600 8-N-1).
Booting µClinux on the RSK
Once powered on the boot loader program will check some basic settings, and display a splash screen.
Once the boot loader has completed it will pass handling of the boot sequence to the Linux decompressor, this
decompression process will take around 2 seconds.
When the Linux decompressor has completed, the LEDs on the RSK board will begin to cycle. This indicates the first phase
of the boot sequence is complete.
The QVGA screen will then clear and display a black screen with the Linux Tux Penguin. This indicates that the QVGA
driver has successfully loaded, and boot is nearly complete.
