Installing ELDK 4.1 on FreeBSD 6.2

Last updated: April 21, 2007.

Under construction

Although the ELDK is meant to be run on Linux, it is possible to run it on FreeBSD 6.2 if the Linux compatibility environment is installed.

Installing and configuring FreeBSD 6.2

Install a FreeBSD distribution. (E.g. the X-kern-developer distribution).

Add the following packages:

	linux_base-fc-4_9
	gmake-3.81_1
	bash-3.1.17
	firefox-1.5.0.8,1

Configure the system to load the linux module at startup and to run the nfs, rpc and (optionally) the ntp daemon.

/etc/rc.conf should contain the following lines:

	linux_enable="YES"
	nfs_server_enable="YES"
	rpcbind_enable="YES"
	ntpd_enable="YES"

/etc/exports should look like:

	/opt/eldk/ppc_8xx  -maproot=0:0

/etc/ntp.conf might look like

	server 0.europe.pool.ntp.org
	server 1.europe.pool.ntp.org
	server 2.europe.pool.ntp.org
	server 3.europe.pool.ntp.org

Installing the ELDK 4.1

Download an ELDK version from ftp.denx.de. The cc1000 is based on the uclibc-freescale distribution
Burn a CD and mount it or mount the ISO image using mdconfig (untested).

Replace temporarily make by gmake

	mv /usr/bin/make /usr/bin/make.org
	ln -s /usr/local/bin/gmake /usr/bin/make

Install the ELDK
```
	cd /cdrom
	./install -d /opt/eldk -a ppc_8xx
```
Ignore the errors during kernel configurations (normal and xenomai kernel)
Copy the ELDK_MAKEDEV and ELDK_FIXOWNER scripts from the cd to e.g. /tmp

Change line 57 of ELDK_MAKEDEV from

	if [ -e $arch ]; then

	if [ ! -n $arch ]; then

and run it

	./ELDK_MAKEDEV -d /opt/eldk -a ppc_8xx

Ignore the error on 'seq'.

Change the interpreter of the ELDK_FIXOWNER script from

	#!/bin/bash

	#!/usr/local/bin/bash

and run it

	./ELDK_FIXOWNER -d /opt/eldk -a ppc_8xx

Remove the gmake link

	rm /usr/bin/make
	mv /usr/bin/make.org /usr/bin/make

With the exception of GDB the development environment is ready now. See the description of the BDM Interface on how to build GDB.

Test the NFS mount

Connect the serial port of the CC1000 to the serial port of the development PC.
Start 'cu' (probably requires root permission)
```
	cu -l /dev/ttyd0 -s 9600
```
Power-on the CC1000. You should see the U-BOOT initial messages now.

Test the cross compiler and linker

Set the environment variable CROSS_COMPILE (add it to your profile)
```
	CROSS_COMPILE=ppc-linux- ; export CROSS_COMPILE
```

Add /opt/eldk/usr/bin to your path

	PATH=/opt/eldk/usr/bin:$PATH ; export PATH

Put a test program somewhere where the CC1000 can access it and compile it:

	cd /opt/eldk/ppc_8xx/tmp
	cat << E_O_F > test.c
	#include 
	main()
	{
		printf("Running on CC1000\n");
	}
	E_O_F
	ppc-linux-gcc -c -I../usr/include test.c
	ppc-linux-ld ../lib/crt1.o test.o -o test ../lib/libc.a

Boot the CC1000 from NFS
Run the testprogram on the CC1000
```
	cd /tmp
	./test
```
