The following procedure assumes that the ChorusOS 4.0 product has already been correctly installed on the host workstation. See the ChorusOS 4.0 Installation Guide for Solaris Hosts.
Create and change to a build directory where you will build system images:
$ mkdir build_dir $ cd build_dir |
Set an environment variable to use with the configure(1CC) command as a shortcut to the base directory.
For example:
Set the environment variable... |
To the family-specific product directory. The default value is... |
---|---|
DIR |
/opt/SUNWconn/SEW/4.0/chorus-mpc860 |
Make sure your PATH has been set correctly to include the directory install_dir/4.0/chorus-mpc860/tools/host/bin, where the default install_dir is /opt/SUNWconn/SEW. Also make sure that your PATH includes /usr/openwin/bin, which contains the imake utility.
Configure the build directory, using the configure(1CC) command:
If you are building from a binary distribution:
$ configure -b $DIR/kernel \ $DIR/os \ $DIR/tools \ -s $DIR/src/nucleus/bsp/drv \ $DIR/src/nucleus/bsp/powerpc \ $DIR/src/nucleus/bsp/powerpc/mpc8xxADS \ $DIR/src/iom |
The above command configures the build directory to include components installed during a "Default Install". It does not include optional components, such as the X library or code examples, that you may choose to install separately on Solaris host workstations. For example, in order to include everything in your build environment:
$ configure -b $DIR/kernel \ $DIR/os \ $DIR/opt/X11 \ $DIR/tools \ -s $DIR/src/nucleus/bsp/drv \ $DIR/src/nucleus/bsp/powerpc \ $DIR/src/nucleus/bsp/powerpc/mpc8xxADS \ $DIR/src/iom \ $DIR/src/opt/examples |
If you are building from the source distribution, see the ChorusOS 4.0 Production Guide.
As a result of configuration, build_dir now contains a Makefile, which is used to generate the build environment, and a Paths file, which specifies paths to files required by and created in the build environment.
Generate the build environment:
$ make |
Build a system image:
$ make chorus |
The resulting system image file is located in the build directory, build_dir and is called chorus.RAM.
You can also make a smaller system image that includes only the operating system kernel:
$ make kernonly |
See the ChorusOS 4.0 Installation Guide for Solaris Hosts for instructions on how to configure the boot server.
Copy the system image to the boot server.
For example, on a Solaris host workstation:
$ rcp chorus.RAM boot_server:/tftpboot |
Verify that everyone has at least read access to the system image on the boot server.
For example:
$ rlogin boot_server Password: password_for_user $ ls -l /tftpboot/chorus.RAM -rwxr-xr-x 1 user group 1613824 Dec 15 17:33 chorus.RAM* |
(Optional) While logged in to the boot server, create a configuration file for the target.
For a target system with IP address 129.157.173.199 using a boot server with IP address 129.157.173.144, the configuration file contains the following:
AUTOBOOT=YES BOOTFILE=chorus.RAM BOOTSERVER=129.157.173.144
The configuration file is named /tftpboot/819DADC7.ChorusOS.4.0, which is constructed from the target system IP address 129.157.173.199 as a concatenation of the following:
129 in decimal translates to 81 in hexadecimal
157 in decimal translates to 9D in hexadecimal
173 in decimal translates to AD in hexadecimal
199 in decimal translates to C7 in hexadecimal
(optional) .ChorusOS.4.0 identifies the release, and is appended to the concatenation of the IP address expressed in hexadecimal.
The system first attempts to find the configuration file with the .ChorusOS.4.0 extension. If it fails to find one, however, it attempts to find a configuration file without the .ChorusOS.4.0 extension.
mpc8bug
Host Debuggermpc8bug
Host DebuggerThe following procedure concerns mpc8xx FADS target systems reference platforms.
Install Motorola's ADI host debugger (mpc8bug
) on the boot host.
The MPC8XX ADS Software(MPC8bug v 1.5) package
contains the mpc8bug
monitoring tool, configuration
files for all reference targets, and documentation explaining how to install
and use the tool.
See the mpc8bug
installation
manual for details about installation.
Append a "ChorusOS load" macro to the .mpctcl.cfg configuration file.
The following TCL macro should be appended at the
end of the .mpctcl.cfg file that is provided as part
of the mpc8bug
package:
a chload reset :h \; load \$1 \; rms der decie 0 \; rms der extie 0 \; rms der prie 0 \; rms der sysie 0 \; rms der trie 0 \; rms der mcie 0 \; rms der itlbmse 0 \; rms der dtlbmse 0 \; rms der itlbere 0 \; rms der dtlbere 0 \; go
The above rms der xx 0 commands allow the ChorusOS kernel to handle the coresponding exceptions.
Connect the Host ADI and Target Debug ports.
The MPC8xx[F]ADS board must be installed and configured to operate in Host Controlled configuration mode via its ADI port. Therefore, you must plug an ADI board into one of the SBus or ISA slots of the boot host and connect to the MPC8xx[F]ADS through a 37-pin flat cable.
See the section "Installation Instructions" in the MPC8xx[F]ADS User's Manual for details about installing the ADI board and configuring the target to boot from the Debug port.
Once this is done, you can start the mpc8bug
monitor utility on the boot host as follows:
Connect the target system and boot system RS232 ports.
Connect the target system RS232 port on SMC1 to the boot system serial port for the ChorusOS debug agent link and system console.
Restart the target system.
Start the mpc8bug
monitor:
$ mpc8bug ADI ADS |
ADI is the number, from 0 to 3, of the SBus expanstion slot for the ADI board on the SPARCstation host system, or the address of the ADI card divided by 0x100 for a PC/AT host.
ADS is the ADI address, from 0 to 3, of the MPC8xx[F]ADS target board, as determined by the ADDR switches on the DS1 Dip-Switch of the MPC8xx[F]ADS board.
When started, the mpc8bug
monitor automatically executes the commands included in the configuration
files:

Executing .mpc8xx.cfg file from the current directory. Executing .mpc860.cfg file from the current directory. Executing .mpcsdram.cfg file from the current directory. f860Bug> |
Make sure the MPC8xx[F]ADS hardware is in a working state by running the diagnostic tests T1, T2, T3 and T4 that are provided by the mpc8bug monitor.
See the mpc8bug
documentation
for details about using mpc8bug
and associated diagnostic programs.

bootMonitor
In order to boot the target from flash memory you must perform the following procedures.
bootMonitor
ImageSee bootMonitor(1CC)
for details about how bootMonitor
works.
Create a build directory where you will build a bootMonitor
image:
$ mkdir bootmon $ cd bootmon |
Note that this build directory is different from the directory where you build system images.
Configure the bootMonitor
build directory based on the binary distribution:
$ configure -b $DIR/kernel \ $DIR/os \ $DIR/tools \ -s $DIR/src/nucleus/bsp/drv \ $DIR/src/nucleus/bsp/powerpc \ $DIR/src/nucleus/bsp/powerpc/mcp8xxADS \ $DIR/src/iom |
Generate the build environment:
$ make |
Edit the special bootmon/conf/mini profile so that it reads:
# # Mini Profile # # # Kernel features # -set USER_MODE=false -set VIRTUAL_ADDRESS_SPACE=false -set SEM=false -set EVENT=false -set MONITOR=false -set TIMER=false -set DATE=false -set RTC=false -set PERF=false -set IPC=false -set MIPC=false -set LAPBIND=true # Change this from 'false' to 'true' -set LAPSAFE=true # Change this from 'false' to 'true' -set MON=false -set LOG=false
Configure the build environment for bootMonitor
:
$ configurator -p conf/mini $ configurator -set BOOT_MODE=ROM $ configurator -setenv ETHER_ADDR=xx:xx:xx:xx:xx:xx |
As you enter the commands above, replace xx:xx:xx:xx:xx:xx with the target system Ethernet address.
Build a bootMonitor
image:
$ make bootMonitor |
The resulting system image file is located in the build directory, bootmon and is called bootMonitor.ROM.
bootMonitor
ImageRestart the target system.
Start the mpc8bug
tool.
See Step 6 for details.
Use the loadf command to flash the bootMonitor:
f860Bug> reset :h ; loadf full_path/bootMonitor.ROM 0x100000 Initializing memory controller and UPM for 50MHZ DRAM delay set to 60ns DRAM size set to 4Mbytes loadf: Loading ELF file . . .

Power off the target board.
Unplug the ADI cable.
Restart the target system.
See Step 7 for an example of the messages displayed on the target system console.
