 Sorry, there is no document.

 > Can I run Net BSD on it? How?

 1) Make cross compiler (binutils, egcs)

	1-1) get patches from

		ftp://ftp.netbsd.org/pub/NetBSD/arch/sh3/crosskit/

	1-2) get snapshot from

		ftp://ftp.netbsd.org/pub/NetBSD/arch/sh3/snapshot/

	1-3) make binutils

		Extract binutils and patch.

		Apply patch

		./configure --target=sh-xxx-netbsdcoff
			or
		./configure --target=shel-xxx-netbsdcoff
			or
		./configure --target=sh-xxx-netbsdelf
			or
		./configure --target=shel-xxx-netbsdelf

	     (I recommend coff because latest snapshot is coff)

		make
		make install

	1-4) extract the snapshot and copy the include files and libraries
	     into /usr/local/sh-*-netbsdcoff/include and
	     /usr/local/sh-*-netbsdcoff/lib.

	1.5) make egcs

		Do:

			cd /usr/local/sh-*-netbsdcoff
			ln -s include sys-include

		(for limits.h)

		Extract egcs and patch

		Edit egcs-1.1.2-netbsdsh-19991220-2.dif appropriately

		Apply patches

		./configure --target=sh-xxx-netbsdcoff
			or
		./configure --target=shel-xxx-netbsdcoff
			or
		./configure --target=sh-xxx-netbsdelf
			or
		./configure --target=shel-xxx-netbsdelf

		make
		make install

		cd /usr/local/lib/gcc-lib/sh-*-netbsdcoff/egcs-version/
		rm lib*.a */lib*.a

	1.6) make cross compile script

		Copy usr/src/sys/arch/evbsh3/conf/build-sh into your PATH

		Edit the script. You have to modify following entries

			MACHINE
			TARGET

 2) edit kernel sources:

	2.1) check your system

		CPU type
		byte order
		internal and external clock frequency
		the settings of the Bus State Controller (includes memory map)

	2.2) edit config file

		Add an option to specify CPU type

			# if the system has SH3, enable one of the following
			# options
			options SH7708
			options SH7708R
			options SH7708S
			options SH7709
			options SH7709A

			# if the system has SH4, enable following options
			options	SH7750
			options SH4

		(Note that -current doesn't work under SH4)

		Set BSC value and any other values.
		Example:

		options         PCLOCK=25000000         # 25.000MHz
		options         IOM_ROM_SIZE=0x00200000 # 1MB
		options         IOM_RAM_SIZE=0x01000000 # 16MB
		options         LED_ADDR=0xb8000000

		options         BSC_BCR1_VAL    =0x0008
		options         BSC_BCR2_VAL    =0x3fd0
		options         BSC_WCR1_VAL    =0x3ff3
		options         BSC_WCR2_VAL    =0xffdf
		options         BSC_MCR_VAL     =0x0004
		options         BSC_SDMR_VAL    =0xffffe088
		options         BSC_RTCSR_VAL   =0xa508
		options         BSC_RTCNT_VAL   =0xa500
		options         BSC_RTCOR_VAL   =0xa582
		options         FRQCR_VAL       =0x0122
		options         PFC_SCPCR_VAL   =0x00aa

		(NOTE: I'm now working to make IPL program. These values
		 will be set by the IPL)

	2.3) If your system is little endian, edit evbsh3/include/endian.h

	2.4) If the main memory of your system is started from area 2
	     (i.e. 0x0800000 in phys), edit

			sh3/include/param.h
			sh3/sh3/md_root.c
			evbsh3/evbsh3/locore.s
			evbsh3/evbsh3/machdep.c
			evbsh3/include/param.h
			evbsh3/include/sh3.h

		(This problem will be fixed in near future)

	2.5) make kernel

		config
		make depend
		make

		NOTE: If you want to make ROM image, add followng entry into
		config file:

			options ROMIMAGE
	2.6) Burn ROM (or FLASH)

		NOTE: the kernel is expected to locate at
		0xa0010000 or 0x80010000 (ROM) or 0x8c010000 (RAM).
		You have to write program to jump this address.
		For example:

		        .text

		        .globl  __start
		__start:
		        .globl  start
		start:
		        mov.l   Xstart, r0
		        jmp     @r0
		        nop

		Xstart: .long 0x80010000
