LANBIC Linux Setup Manual

 This document is the setup manuals of the SH-Linux evaluation environment for evaluating LANBIC 
 as a Linux platform. 

[Setup Procedure]

1 Host PC
 I prepared to Fodera Core 2 PC as SH-GCC environment.
 Therefore, there is no operating result except the environment. 


2 Toolchain
 Extend "toolchain_345.tar.gz" under any directory.
Ex)
	# cp /.../toolchain_345.tar.gz /home
	# cd /home
	# tar zvxf toolchain_345.tar.gz
	# export PATH=/home/usr/local/bin:$PATH


3 Bootloader
3.1 Expand "ipl+eth.tar.gz" under any directory.
Ex)
	# cp /.../ipl+eth.tar.gz /home
	# cd /home/
	# tar xvzf ipl+eth.tar.gz

3.2 Bootloader compiling
 If the compiling of bootloader finishes normally, "sh-stub.srec" is made under "/ipl+eth".
	# cd ipl+eth/
	# make

3.3 Writing bootloader
 If you write bootloader to the on-board flash memory, please setup these following process.

3.3.1 Change the on-board dip switch in order to start the monitor program in EPROM.
+-------------------+-------------------------------+-------------------------------+
|AREA0			|Flash ROM			|EEPROM                         |
+-------------------+-------------------------------+-------------------------------+
|Bit			|1   2   3   4   5   6   7   8	|1   2   3   4   5   6   7   8  |
+-------------------+-------------------------------+-------------------------------+
|FROM Board SW1		|ON  OFF OFF OFF OFF ON  ON  OFF|ON  OFF OFF OFF OFF ON  ON  OFF|
+-------------------+-------------------------------+-------------------------------+
|LANBIC CORE SW1	|ON  OFF OFF OFF OFF OFF OFF OFF|ON  ON  ON  OFF OFF OFF OFF OFF|
+-------------------+-------------------------------+-------------------------------+
|LANBIC CORE SW3	|ON  OFF OFF OFF ON  OFF OFF OFF|ON  OFF ON  OFF ON  OFF OFF OFF|
+-------------------+-------------------------------+-------------------------------+

3.3.2 Connect between CN6 of Lanbic Main Core board and the monitor PC via RS232 cross cable.

3.3.3 Start the terminal software on PC and set up the following serial communication protocol. 

	Baud rate	:38400kbps
	Data		:8 bits
	Parity		:none
	Stop		:1 bit
	Flow control:none

3.3.4 The switch of the power supply (SW8) is turned on and confirm the following message 
 on the terminal.
	ITS-DS7 monitor (38.4 Kbps SCIF2) Cache off
	-Little endian on EPROM
	2004.04.23-01 Ver.4.2.1 for core + func
	>

3.3.5 Practice "LF" command, then confirm the following message on the terminal.
	> LF
	RAM Clear.....
	please send!('.'& CR stop load)

3.3.6 Open the Send file window ([File] -> [Send file...]). After you select "sh-stub.srec", 
 the Flash ROM write program is started. If you confirm the followng message, the switch of 
 the power supply (SW8) is turned off.
	Erasing.
	Writing.
	>

3.3.7 Dip switches are returned to the original setup and the switch of the power supply is 
 turned on again, the updated bootloader is operated.


4 Root file system
 Extend "rootfs.tar.gz" under any directory.
Ex)
	# cp /.../rootfs.tar.gz /home
	# cd /home
	# tar xvzf rootfs.tar.gz

5 Linux-kernel
5.1 Extend "linux-2.6.10.tar.gz" under any directory.
Ex)
	# cp /.../linux-2.6.10.tar.gz /home
	# cd /home
	# tar xvzf linux-2.6.10.tar.gz

5.2 Kernel environment initializaton
 .config is the kernel configuration file. 
 When the source code of sh-Linux is newly installed, it is necessary to initialize the compiler 
 environment.
	# cp -p .config Config
	# make mrproper
	# cp -p Config .config

5.3 Kernel configuration
 If you operate the following command, you can see the kernel configuration window.
	# make menuconfig

5.4 Kernel compiling
 If compiling is finished normally, the kernel image file (zImage) is made under "arch/sh/boot/ "
	# make zImage

 Put "zImage" to the file system (under "/home/rootfs").

6 Linux evaluation environment
 The SH-Linux evaluation environment achieves the network file system by using the DHCP function 
 and the NFS server function of Linux PC. 
 Therefore, you should set the DHCP server and the NFS server of Linux PC. 
 Concretely, it is necessary to edit the following file. 

	[DHCP server setup]
	# vi /etc/dhcpd.conf
	
	ddns-update-style ad-hoc;
	default-lease-time 600;
	max-lease-time 7200;
	log-facility local7;
	option domain-name-servers 192.168.10.100;
	
	subnet 192.168.10.0 netmask 255.255.255.0 {
	}
	
	host LANBIC {
	hardware ethernet **:**:**:**:**:**;	# Target MAC Address
	fixed-address 192.168.10.232;			# Target IP Address
	filename "/home/rootfs/zImage";
	option root-path "/home/rootfs";
	}

	[NFS server setup]
	# vi /etc/exports
	
	/home/rootfs 192.168.10.0/255.255.255.0(rw,sync,no_root_squash)

	[DHCP and NFS server restarting]
	# /etc/rc.d/init.d/portmap restart
	# /etc/rc.d/init.d/nfs restart
	# /etc/rc.d/init.d/nfslock restart
	# /etc/rc.d/init.d/dhcpd restart

7 Lanbic starting procedure
7.1 In order to operate the bootloader, the setup of the serial terminal is as follows.
	Baud rate	:38400kbps
	Data		:8 bits
	Parity		:none
	Stop		:1 bit
	Flow control:none

7.2 Bootloader starting
 An effective command is only "n" and "z" in this. 
 That is, the linux kernel(zImage file) is downloaded from the LinuxPC(DHCP server) by "n" command.
 And, the linux kernel is started by "z" command.
